Μια άπτερη μύγα προσαρμοσμένη στις νυχτερίδες

Η Penicillidia dufourii είναι μικρή, άπτερη παρασιτική μύγα της οικογένειας Nycteribiidae. Τα ενήλικα ζουν στην εξωτερική επιφάνεια του σώματος των νυχτερίδων και τρέφονται με το αίμα τους. Η ασυνήθιστη εμφάνισή της, με μικρή κεφαλή και μακριά πόδια, θυμίζει περισσότερο μικροσκοπική αράχνη παρά συνηθισμένη μύγα. Παραμένει όμως έντομο, με τρία ζεύγη ποδιών.

Η οικογένεια Nycteribiidae περιλαμβάνει περισσότερα από 270 περιγραμμένα είδη παγκοσμίως. Το γένος Penicillidia περιλαμβάνει περίπου 25 είδη, επιπλέον των υποειδών, σύμφωνα με τον παγκόσμιο κατάλογο της οικογένειας. Οι Nycteribiidae ανήκουν στην υπεροικογένεια Hippoboscoidea και παρουσιάζουν ιδιαίτερα έντονες προσαρμογές στην παρασιτική ζωή.

Μορφολογία και αναγνώριση

Η Penicillidia dufourii έχει μήκος περίπου 3,4–4 χιλιοστά. Το σώμα φέρει τρίχες και ισχυρά πόδια που διευκολύνουν την κίνηση μέσα στο τρίχωμα του ξενιστή. Η κεφαλή είναι μικρή και, στη θέση ανάπαυσης, αναδιπλώνεται προς τον θώρακα. Η απουσία πτερύγων είναι μόνιμο χαρακτηριστικό των ενηλίκων Nycteribiidae.

Η σωματική κατασκευή επιτρέπει στις μύγες αυτές να κινούνται προς διαφορετικές κατευθύνσεις μέσα στο τρίχωμα. Τα ενήλικα παραμένουν στον ξενιστή κατά το μεγαλύτερο μέρος της ζωής τους.

Η ασφαλής διάκριση από συγγενικά είδη, όπως η Penicillidia conspicua, απαιτεί εξέταση λεπτών μορφολογικών χαρακτήρων. Οι ταξινομικές κλείδες χρησιμοποιούν τη μορφή της κεφαλής, τη διάταξη τριχών και ακανθών, τις κοιλιακές πλάκες και τα γεννητικά εξαρτήματα. Η γενική εμφάνιση μιας άπτερης μύγας πάνω σε νυχτερίδα δεν αρκεί για αναγνώριση σε επίπεδο είδους.

Εξάπλωση και παρουσία στην Κύπρο

Το ονομαστικό υποείδος, Penicillidia dufourii dufourii, απαντά στην ηπειρωτική Ευρώπη, στη Βόρεια Αφρική και στη νοτιοδυτική Ασία, με εξάπλωση προς τα δυτικά Ιμαλάια και το ανατολικό Καζακστάν.

Η παρουσία στην Κύπρο τεκμηριώθηκε στη μελέτη των Ševčík, Benda και Lučan, που δημοσιεύθηκε το 2013. Στην περιοχή της Κακοπετριάς καταγράφηκαν δύο θηλυκά από Myotis blythii στις 15 Οκτωβρίου 2005 και ένα αρσενικό από νυχτερίδα αναγνωρισμένη ως Myotis nattereri στις 13 Οκτωβρίου 2005. Τα δείγματα προέρχονταν από εγκαταλελειμμένες μεταλλευτικές στοές στο Τρόοδος.

Αυτές αποτέλεσαν τις πρώτες δημοσιευμένες καταγραφές του είδους από την Κύπρο. Η πρώτη επιστημονική καταγραφή δηλώνει την τεκμηρίωση της παρουσίας του, όχι τον χρόνο άφιξής του στο νησί.

Ξενιστές και οικολογικές σχέσεις

Οι κύριοι ξενιστές στην ευρύτερη εξάπλωση του είδους είναι οι Myotis myotis και Myotis blythii. Έχει επίσης καταγραφεί από άλλες νυχτερίδες, μεταξύ των οποίων η Miniopterus schreibersii. Οι συγκεκριμένοι κυπριακοί ξενιστές της μελέτης του 2013 ήταν οι M. blythii και M. nattereri.

Η χρήση κοινών καταφυγίων από διαφορετικά είδη νυχτερίδων δημιουργεί ευκαιρίες μεταφοράς παρασίτων μεταξύ ξενιστών. Η P. dufourii παρουσιάζει προτίμηση σε νυχτερίδες του γένους Myotis, αλλά δεν περιορίζεται αποκλειστικά σε ένα είδος.

Έρευνα του 2024 σε καταφύγια νυχτερίδων έδειξε ότι η εποχή και η σύνθεση της κοινότητας των ξενιστών μπορούν να επηρεάζουν τις καταγεγραμμένες παρασιτικές σχέσεις. Η εύρεση μιας μύγας πάνω σε έναν ξενιστή δεν σημαίνει πάντοτε ότι αυτός είναι ο βασικός της ξενιστής σε ολόκληρη την εξάπλωσή της.

Περισσότερες πληροφορίες για τους ξενιστές υπάρχουν στον κατάλογο των νυχτερίδων της Κύπρου.

Αναπαραγωγή και βιολογικός κύκλος

Οι Nycteribiidae έχουν έναν ιδιαίτερο τρόπο αναπαραγωγής, γνωστό ως αδενοτροφική ζωοτοκία. Το θηλυκό διατηρεί μία αναπτυσσόμενη προνύμφη στο σώμα του και την τρέφει με εκκρίσεις ειδικών αδένων, που αποκαλούνται «γαλακτογόνοι αδένες». Η προνύμφη ολοκληρώνει εκεί την ανάπτυξή της μέχρι την τρίτη ηλικία.

Λίγο πριν από την απόθεση, το θηλυκό εγκαταλείπει προσωρινά τη νυχτερίδα και αποθέτει την ώριμη προνύμφη σε επιφάνεια του καταφυγίου. Η προνύμφη στερεώνεται στο υπόστρωμα και νυμφώνεται πολύ γρήγορα. Το θηλυκό επιστρέφει στον ξενιστή, ενώ το νέο ενήλικο, μετά την έξοδό του από το πουπάριο, αναζητά νυχτερίδα.

Έτσι, η προνυμφική ανάπτυξη γίνεται μέσα στη μητέρα, η νύμφωση στο καταφύγιο και η ενήλικη ζωή κυρίως πάνω στον ξενιστή. Οι διάρκειες ανάπτυξης εξαρτώνται από το είδος και τις περιβαλλοντικές συνθήκες και δεν αποτελούν σταθερό ημερολόγιο για την P. dufourii στην Κύπρο.

Ενδιαίτημα και διασπορά

Το ενδιαίτημα περιλαμβάνει τόσο το σώμα των νυχτερίδων όσο και τα καταφύγιά τους. Η κυπριακή καταγραφή από μεταλλευτικές στοές δείχνει τη σύνδεση του είδους με υπόγειους χώρους που χρησιμοποιούνται από τους ξενιστές.

Επειδή τα ενήλικα δεν πετούν, η μεταφορά τους σε μεγαλύτερες αποστάσεις συνδέεται με τις μετακινήσεις των νυχτερίδων. Μέσα στις αποικίες, η εγγύτητα των ζώων και η κοινή χρήση του καταφυγίου διευκολύνουν την επαφή με νέους ξενιστές. Η παρουσία κατάλληλων νυχτερίδων και χώρων νύμφωσης είναι επομένως ουσιαστική για τη διατήρηση του κύκλου ζωής.

Παράσιτα πάνω στο ίδιο το παράσιτο

Η Penicillidia dufourii μπορεί να φιλοξενεί μικροσκοπικούς μύκητες της τάξης Laboulbeniales. Στην ευρωπαϊκή βιβλιογραφία έχουν αναφερθεί πάνω της οι Arthrorhynchus nycteribiae και A. eucampsipodae.

Πρόκειται για χαρακτηριστικό παράδειγμα υπερπαρασιτισμού: η μύγα παρασιτεί στη νυχτερίδα και ο μύκητας στη μύγα. Μελέτες έχουν δείξει ότι η P. dufourii αποτελεί δευτερεύοντα ξενιστή του A. nycteribiae, συγκριτικά με την P. conspicua. Αυτές οι ευρωπαϊκές παρατηρήσεις δεν συνιστούν καταγραφές των μυκήτων από την Κύπρο.

Σύγχρονη επιστημονική έρευνα

Το 2024 δημοσιεύθηκε το πλήρες μιτοχονδριακό γονιδίωμα της Penicillidia dufourii. Περιλαμβάνει 15.354 ζεύγη βάσεων και 37 γονίδια. Η ανάλυση υποστήριξε την τοποθέτησή της στην οικογένεια Nycteribiidae και προσέφερε μοριακά δεδομένα για συγκρίσεις με συγγενικά είδη.

Η συνδυασμένη χρήση μορφολογίας και γενετικών δεδομένων βοηθά στην αναγνώριση αυτών των εξειδικευμένων παρασίτων και στην κατανόηση των σχέσεών τους με τις νυχτερίδες.

Bat fly – Penicillidia (Penicillidia) dufourii (Westwood, 1835) – Nycteribiidae – Cyprus

Text by George Konstantinou.

A wingless fly adapted to bats

Penicillidia dufourii is a small, wingless parasitic fly belonging to the family Nycteribiidae. Adults live on the external surface of bats and feed on their blood. Its unusual appearance, with a small head and long legs, resembles a miniature spider more than an ordinary fly. However, it is an insect, with three pairs of legs.

The family Nycteribiidae contains more than 270 described species worldwide. The genus Penicillidia comprises approximately 25 species, in addition to subspecies, according to the world checklist of the family. Nycteribiidae belong to the superfamily Hippoboscoidea and display particularly pronounced adaptations to parasitic life.

Morphology and identification

Penicillidia dufourii measures approximately 3.4–4 mm. Its body bears bristles and strong legs that facilitate movement through the host’s fur. The head is small and, at rest, folds back towards the thorax. The absence of wings is a permanent feature of adult Nycteribiidae.

Their body structure allows these flies to move in different directions through the fur. Adults remain on their host for most of their lives.

Reliable separation from related species, such as Penicillidia conspicua, requires examination of fine morphological characters. Identification keys use head shape, the arrangement of bristles and spines, abdominal plates and genital structures. The general appearance of a wingless fly on a bat is insufficient for species identification.

Distribution and occurrence in Cyprus

The nominate subspecies, Penicillidia dufourii dufourii, occurs in continental Europe, North Africa and southwestern Asia, extending towards the western Himalayas and eastern Kazakhstan.

Its presence in Cyprus was documented in the study by Ševčík, Benda and Lučan, published in 2013. Near Kakopetria, two females were recorded from Myotis blythii on 15 October 2005, and one male from a bat identified as Myotis nattereri on 13 October 2005. The specimens came from abandoned mine galleries in the Troodos Mountains.

These constituted the first published records of the species from Cyprus. A first scientific record establishes documented presence, rather than the time at which a species arrived on the island.

Hosts and ecological relationships

The principal hosts across the species’ wider distribution are Myotis myotis and Myotis blythii. It has also been recorded from other bats, including Miniopterus schreibersii. The specific Cypriot hosts in the 2013 study were M. blythii and M. nattereri.

Shared roosts used by different bat species create opportunities for parasites to transfer between hosts. P. dufourii shows a preference for bats of the genus Myotis, but is not restricted exclusively to a single species.

Research published in 2024 on bat roosts showed that season and host-community composition can influence recorded parasitic relationships. Finding a fly on a particular host does not necessarily mean that this is its principal host throughout its distribution.

Further information about the hosts is available in the list of bats of Cyprus.

Reproduction and life cycle

Nycteribiidae have a distinctive reproductive strategy known as adenotrophic viviparity. A female retains one developing larva inside her body and nourishes it with secretions from specialised glands, known as “milk glands”. The larva completes its development there up to the third instar.

Shortly before deposition, the female temporarily leaves the bat and deposits the mature larva on a surface within the roost. The larva attaches to the substrate and pupates rapidly. The female returns to her host, while the new adult searches for a bat after emerging from its puparium.

Thus, larval development takes place inside the mother, pupation occurs in the roost, and adult life is spent mainly on the host. Development times depend on species and environmental conditions and do not provide a fixed timetable for P. dufourii in Cyprus.

Habitat and dispersal

The habitat includes both the bats’ bodies and their roosts. The Cypriot records from mine galleries demonstrate the species’ association with underground spaces used by its hosts.

Because adults cannot fly, transport over longer distances is associated with bat movements. Within colonies, proximity between animals and shared use of the roost facilitate contact with new hosts. Suitable bats and pupation sites are therefore essential for maintaining the life cycle.

Parasites on the parasite itself

Penicillidia dufourii can host microscopic fungi belonging to the order Laboulbeniales. European literature has reported Arthrorhynchus nycteribiae and A. eucampsipodae on this fly.

This is a characteristic example of hyperparasitism: the fly parasitises the bat, and the fungus parasitises the fly. Studies have shown that P. dufourii is a secondary host of A. nycteribiae compared with P. conspicua. These European observations do not constitute records of the fungi from Cyprus.

Modern scientific research

The complete mitochondrial genome of Penicillidia dufourii was published in 2024. It contains 15,354 base pairs and 37 genes. The analysis supported its placement within Nycteribiidae and provided molecular data for comparisons with related species.

Combining morphology and genetic information helps identify these specialised parasites and understand their relationships with bats.

Key words: Nycteribiidae, Streblidae, first records, distribution, hosts


1. Introduction

The family Nycteribiidae Samouelle, 1819 comprises the dipterans parasitising on bats of all zoogeographical regions. According to the checklist by Graciolli and Dick (2008), more than 270 species occur in the world. Seventeen species (5 genera) are known from the western Palaearctic (Theodor, 1967; Hůrka and Soós, 1986a), and 14 species (5 genera) of them occur in the Mediterranean area (Hůrka, 1964; Theodor, 1967).
No detailed information on Nycteribiidae has been available from Crete, except for several records of 3 species reported by Theodor (1967) and Kock (1974, 1989): Nycteribia pedicularia Latreille, 1805 (collected from Myotis capaccinii (Bonaparte, 1837)), Nycteribia schmidlii Schiner, 1853 (from M. capaccinii and Miniopterus schreibersii (Kuhl, 1817)), and Phthiridium biarticulatum Hermann, 1804 (from Rhinolophus ferrumequinum (Schreber, 1774)). A similar situation holds for the nycteribiid fauna of Cyprus: only scarce data have been available from this island, including records of 5 species, Nycteribia pedicularia (from M. capaccinii), N. schmidlii (from Rhinolophus euryale Blasius, 1853), Phthiridium biarticulatum (from R. euryale), Basilia daganiae Theodor and Moscona, 1954 (from Pipistrellus kuhlii (Kuhl, 1817)), and Penicilidia conspicua Speiser, 1900 (from M. schreibersii) (Bequaert, 1953; Theodor, 1956, 1967; Kock, 1974, 1984, 1989).
* Correspondence: martin.sevcik@hotmail.sk
The family Streblidae Kolenati, 1863 is represented by 4 species of 3 genera in the Mediterranean (Jobling, 1939; Hůrka and Soós, 1986b). Just one species, Brachytarsina flavipennis Macquart, 1851, occurs in Europe (Hůrka, 1972). So far, no record of this species has been available either from Crete or from Cyprus.

2. Materials and methods

In October 2005, July and October 2006, and May and June 2008, bats were collected from Crete and Cyprus in the course of research trips (Benda et al., 2007, 2009). Mist nets were installed according to standard procedures (Kunz and Kurta, 1988) in front of water, and bats were also captured in their roosts (caves, mines). Each captured host was placed into a separate cloth bag and labelled. Hosts were inspected for bat flies, ectoparasites living in the fur of the body, which were collected with entomological tweezers and preserved in 75% ethanol. Samples for a species of host were stored in an Eppendorf tube. The age and sexual status (adult male (♂ ad), adult female (♀ ad), subadult female (♀ sad)) of the host is given for most samples, with the exception of the period of October 2010, when only the number and species of host were registered. All bat flies were observed freely under a magnifying glass, and keys were used for the determination and comparison of parasitic species: Theodor and Moscona (1954), Theodor (1967, 1975), and Hůrka (1972). Voucher specimens of the parasites are deposited in the collection of the first author (cMŠ). The taxa are arranged alphabetically. The information for each species appears in the following format: synonyms available from the respective islands; published data; new material examined (number and developmental stage of specimens, locality, date, number of collection, age/number of host).

3. Results and discussion

In total, 6 species representing 4 genera belonging to the family Nycteribiidae and 1 species of the family Streblidae were collected from Crete, and 4 species of 2 genera of the family Nycteribiidae and 1 species of Streblidae were collected from Cyprus.

3.1. Family Nycteribiidae (Samouelle 1819)

3.1.1. Subfamily Nycteribiinae Samouelle, 1819, sensu Maa 1965

3.1.1.1. Nycteribia (Nycteribia) latreillii (Leach, 1817) Crete. New material examined: 1♂, 1♀, Lefkogeia, at Venetian bridge ca. 3 km E of Kato Preveli Monastery, 30 May 2008 (cMŠ 3962-3963, leg. P. Benda and V. Hanák) from 2♀♀ ad Myotis blythii.
Remarks: Until Theodor (1954a), the species was reported in Europe under various names, as the proper name was erroneously used for N. kolenati Theodor and Moscona, 1954. The distribution of N. latreillii corresponds to the ranges of its primary host species, Myotis myotis (Borkhausen, 1797), M. blythii (Tomes, 1857), and M. punicus Felten, 1977, i.e. almost all of continental Europe (northern limit of 51°N–52°N), the Maghreb, the Middle East, and Central Asia (Hůrka, 1964; Theodor, 1967). In addition, it can also occur on other species of the genus Myotis Kaup, 1829, Miniopterus Bonaparte, 1837, and Rhinolophus Lacépède, 1799, as well as on other cavedwelling bats (see Theodor, 1967). Our findings represent the first evidence of this species from Crete. Although we did not find this bat fly in Cyprus, its occurrence is to be expected due the presence of one of the principal host species, M. blythii (Benda et al., 2007).
3.1.1.2. Nycteribia (Nycteribia) pedicularia Latreille, 1805 Crete. Published records: Kock (1974): Piskokefalo at Sitia (host Myotis capaccinii).
Cyprus. Published records: Kock (1974): Kyrenia (host Myotis capaccinii).
Remarks: Nycteribia pedicularia has frequently been confused with N. latreillii and/or N. kolenati Theodor and Moscona, 1954. N. pedicularia is distributed in south-eastern Europe, and the northern limit of its range probably reaches the Alps and southern Carpathians (Hůrka, 1962). In the broader scale of the western Palaearctic, its distribution range encompasses Turkey, Palestine, Iran, Tunisia, and Algeria (Theodor and Moscona, 1954; Theodor, 1967). However, the record from Cyprus is doubtful, as the occurrence of the host species as well as the record itself is in doubt (see Benda et al., 2007). Host species of this bat fly are cave-dwelling bats of the genera Myotis, Miniopterus, and Rhinolophus (Theodor and Moscona, 1954).

3.1.1.3. Nycteribia (Listropoda) s. schmidlii Schiner, 1853

Crete. Published records: Theodor (1967): Limnea (host Miniopterus schreibersii). - Kock (1974): Canea = Chaniá (host Miniopterus schreibersii), Piskokefalo bei Sitia (host Myotis capaccinii).
New material examined: 2♂♂, 1♀, Dramia, Petres river bridge, 6 October 2006 (cMŠ 3400, leg. P. Benda and V. Hanák) from 1♀ ad Myotis capaccinii; 5♂♂, 9♀♀, Argyroupoli, Mouselas river, 3 June 2008 (cMŠ 3973-3974, leg. P. Benda and V. Hanák) from 2♀♀ ad Myotis capaccinii; 3♂♂, 3♀♀, Omalos Plateau, Tzani cave, 1 October 2006 (cMŠ 3360-3375, leg. P. Benda and V. Hanák) from collection 13♂♂ ad and 2♀♀ sad Miniopterus schreibersii.
Cyprus. Published records: Theodor (1967): site
unspecified (host Rhinolophus euryale).
Remarks: The distribution of the western subspecies N. s. schmidlii corresponds to the distributional range of its principal host bat, Miniopterus schreibersii, viz. central and southern Europe, the Middle East, Afghanistan, and North Africa.
3.1.1.4. Phthiridium biarticulatum Hermann, 1804 Synonym: Stylidia biarticulata Hermann, 1804: Theodor (1967: 127).
Crete. Published records: Theodor (1967): Gonia = Mount Gonias (host Rhinolophus ferrumequinum). - Kock (1989): Rethimnon (host Rhinolophus ferrumequinum).
New material examined: 1♂, Kolymvari, mine above village, 9 October 2006 (cMŠ 3426, leg. P. Benda and V. Hanák) from 1♂ ad Rhinolophus ferrumequinum; 2♀♀, Omalos Plateau, Tzani cave, 1 October 2006 (cMŠ 3377-3378, leg. P. Benda and V. Hanák) from 2♂♂ ad Rhinolophus ferrumequinum.
Cyprus. Published records: Theodor (1967): site
undefined (host Rhinolophus euryale).
New material examined: 1♀, Kakopetria, Troodos Forest, abandoned mine 5 km to SW, upper gallery, 13 October 2005 (cMŠ c07, leg. R.K. Lučan) from Rhinolophus ferrumequinum individual of unknown sex and age; 1♂, Afendrika, ruins of Panagia Chrysiotissa church and Asomatos church, 17 October 2005 (cMŠ c02, leg. R.K. Lučan) from 1♂ ad Rhinolophus ferrumequinum (Schreber, 1774); 3♂♂, 6♀♀, Kakopetria, Troodos Forest, abandoned mine 5 km to SW, upper gallery, 27 July 2006
(cMŠ 3335, 3336, leg. P. Benda) from 1♀ ad and 1♀ sad Rhinolophus blasii (Peters, 1866).
Remarks: This cave-dwelling bat fly lives on representatives of the genus Rhinolophus. Its distribution range is circum-Mediterranean and reaches Tajikistan and Kyrgyzstan (Hůrka, 1964). While Rhinolophus ferrumequinum is the most frequent host of this bat fly (Hůrka, 1964), other (mostly cave-dwelling) bats, e.g., Miniopterus schreibersii, Myotis myotis and M. blythii, are less-parasitised hosts (Hůrka, 1964).

3.1.1.5. Phthiridium integrum (Theodor and Moscona, 1954)

Cyprus. New material examined: 3♀♀, Kantara, Kantara castle ruins 3 km to NE, 25 July 2006 (cMŠ 3328, leg. P. Benda) from 1♂ ad Eptesicus anatolicus.
Remarks: This species was described by Speiser (1901) and redescribed by Karaman (1939) based on a record from Egypt. Findings are known from host species of the genera Taphozous Geoffroy, 1818, Rhinolophus and Hipposideros Gray, 1831 from the Middle East: Egypt, Palestine, Jordan, Saudi Arabia, and Yemen (Sanborn and Hoogstraal, 1953; Theodor and Moscona, 1954; Theodor, 1976; Kock and Nader, 1979; Amr and Qumsiyeh, 1993). This species is reported here for the first time from Cyprus and from a new host, Eptesicus anatolicus Felten, 1971.

3.1.1.6. Basilia (Basilia) daganiae Theodor and Moscona, 1954

Cyprus. Published records: Bequaert (1953): Limassol (host Pipistrellus kuhlii). - Theodor (1956): Limassol, (host Pipistrellus kuhlii), site undefined, leg. Lilford (without host). - Theodor (1967): site undefined, leg. Lilford (host Pipistrellus kuhlii). - Kock (1974): Larnaka (host Pipistrellus kuhlii).
Remarks: The distribution range of this species from the “bathybothyra group” covers the whole eastern Mediterranean: Cyprus, Turkey, Syria, Jordan, Egypt, Lebanon, and Palestine (Theodor and Moscona, 1954; Lewis and Harrison, 1962; Hůrka and Soós, 1986a; Benda et al., 2010). Its occurrence outside the eastern Mediterranean region is not excluded, considering the much broader distribution of its main host Pipistrellus kuhlii. B. daganiae has also been recorded from other species of the genus Pipistrellus: P. pipistrellus (Schreber, 1774) from Jordan (Benda et al., 2010).
3.1.1.7. Basilia (Basilia) mongolensis nudior Hůrka, 1972 Crete. New material examined: 2♀♀, Meskla, above creek, 5 October 2006 (cMŠ 3393, leg. P. Benda and V.
Hanák) from 1♂ ad Myotis aurascens; 1♂, 1♀, Katholiko monastery, Agiou Ioanni cave, 27 May 2008 (cMŠ 3958, leg. P. Benda) from 1♀ ad Myotis aurascens.
Remarks: This subspecies from the “bathybothyra group” was described by Hůrka (1972) from the host Plecotus austriacus Fischer, 1829. The full expansion of this subspecies is unknown, and we expect it to be in the same area distribution as the host Myotis nattereri (Kuhl, 1817). Its occurrence on other arboreal host species is not excluded, but it occurs mostly in the “mystacinus group”, viz. M. alcathoe von Helversen and Heller, 2001 (Heddergott, 2009), and in our records from M. aurascens Kusjakin, 1935. Previous records are from Croatia, Greece (Hůrka, 1972), Bulgaria (Hůrka, 1984), Austria (Kock, 1984), Turkey (Aktaş and Hasbenli, 1994; Hasbenli, 1997), and Germany (Heddergott, 2009).

3.1.1.8. Penicillidia (Neopenicillidia) conspicua Speiser, 1901

Crete. New material examined: 3♂♂, 3♀♀, Omalos Plateau, Tzani cave, 1 October 2006 (cMŠ 3360-3375, leg. P. Benda and V. Hanák) from collection 13♂♂ ad and 2♀♀ sad Miniopterus schreibersii; 2♀♀, Milatos, Milatou cave, 7 October 2006 (cMŠ 3422-3425, leg. P. Benda and V. Hanák) from collection 1♀ ad and 3♀♀ sad Miniopterus schreibersii.
Cyprus. Published records: Kock (1989): Emba, Paphos Distr. (host Miniopterus schreibersii).
New material examined: 1♂, 1♀, Neo Horio, Smigies Trail, ca. 3 km to NW, abandoned chromite mine system ‘Magnesia Mine’, 12 October 2005 (cMŠ c03, c04, leg. R.K. Lučan) from 2 Miniopterus schreibersii individuals of unknown sex and age.
Remarks: Penicillidia conspicua is a species bound to its principal host, Miniopterus schreibersii, and its distribution range corresponds to the occurrence of this bat (Hůrka, 1964). Within this range, it has frequently been found also on Myotis myotis and other cave-dwelling bat species (Hůrka, 1964). This parasite species is reported from Crete for the first time here.
3.1.1.9. Penicillidia (Penicillidia) dufourii Westwood, 1835 Crete. New material examined: 2♂♂, 3♀♀, Lefkogeia, at Venetian bridge ca. 3 km E of Kato Preveli Monastery, 30 May 2008 (cMŠ 3962-3963, leg. P. Benda and V. Hanák) from 2♀♀ ad Myotis blythii; 1♂, 1♀, Dramia, Petres river bridge, 6 October 2006 (cMŠ 3400, leg. P. Benda and V. Hanák) from 1♀ ad Myotis capaccinii; 2♂♂, 2♀♀, Argyroupoli, Mouselas river, 3 June 2008 (cMŠ 39733974, leg. P. Benda and V. Hanák) from 2♀♀ ad Myotis capaccinii.
Cyprus. New material examined: 2♀♀, Kakopetria, Troodos Forest, abandoned mine 4 km to SW, lower gallery, 15 October 2005 (cMŠ c05, leg. R.K. Lučan) from 1♂ ad Myotis blythii; 1♂, Kakopetria, Troodos Forest, abandoned mine 5 km to SW, upper gallery, 13 October 2005 (cMŠ c06, leg. R.K. Lučan) from Myotis nattereri individual of unknown sex and age.
Remarks: The subspecies P. d. dufourii is distributed over continental Europe, North Africa, and south-western Asia to the western Himalayas and eastern Kazakhstan. Myotis myotis and M. blythii are the main hosts of this species, but it can also be found on Miniopterus schreibersii, though much more rarely. This parasite species is recorded here for the first time from Crete and Cyprus.

3.2. Family Streblidae Kolenati, 1863

3.2.1. Subfamily Brachytarsininae (Speiser, 1900)

3.2.1.1. Brachytarsina (Brachytarsina) flavipennis Macquart, 1851

Crete. New material examined: 1♂, Patsos, Agiou Antoniou cave, 3 October 2006 (cMŠ 3388, leg. P. Benda and V. Hanák) from 1♀ sad Rhinolophus ferrumequinum; 2♀♀, Katholiko monastery, Agiou Ioanni cave, 27 May 2008 (cMŠ 3958, leg. P. Benda) from 1♀ ad Myotis aurascens.
Cyprus. New material examined: 1♀, Kakopetria, Troodos Forest, abandoned mine 5 km to SW, upper gallery, 13 October 2005 (cMŠ 08, leg. R.K. Lučan) from Rhinolophus ferrumequinum individual of unknown sex and age; 1♂, 2♀♀, Kakopetria, Troodos Forest, abandoned mine 5 km to SW, upper gallery, 27 July 2006 (cMŠ 3336, leg. P. Benda) from 1♀ sad Rhinolophus blasii.
Remarks: B. flavipennis is the only streblid species occurring in the Mediterranean portion of the Palaearctic. This species has a circum-Mediterranean distribution range, and in Europe it reaches the latitude of 40°N–43° N, roughly corresponding to the areas of mean January temperatures of 8 to 10 °C (Jobling, 1951; Hůrka, 1972).
Jobling (1934, 1939) indicated the occurrence of this species in Cyprus and Theodor’s record (1954b) is uncertain, since a direct finding has not been reported. This bat fly is recorded here from both large islands for the first time.
In conclusion, the combination of our new data with previously published information has resulted in an increase in the total number of species of the Nycteribiidae family on Crete from 3 to 7 species, and from 5 to 7 species on Cyprus. In addition to the above discussion, we may expect other species from this family (genera Nycteribia Latreille, 1796, Basilia Miranda-Ribeiro, 1903, and Eucampsipoda Kolenati, 1857) on the individual islands. Nycteribia (Acrocholidia) vexata Westwood, 1835 is a species with a relation to the extension of the principal hosts Myotis myotis and M. blythii (as N. latreilii), whereas the second host was confirmed on the island of Crete (Benda et al., 2008). The principal host of Basilia nana Theodor, 1954, in Middle Eastern countries is M. nattereri (Turkey - Aktaş and Hasbenli, 1994; Hasbenli, 1997; Jordan - Amr and Qumsiyeh, 1993; Benda et al., 2010), and on this basis we can expect this parasitic species to confirm this host from Cyprus (Benda et al., 2007). In addition, on the same island there probably occurs the parasitic species of the host Rousettus aegyptiacus (Geoffroy, 1810), viz. Eucampsipoda aegyptia (Macquart, 1851). The occurrence of this species on island has already been considered by Theodor (1952, 1954a, 1955; see also Kock and Nader, 1979). This host species has been confirmed on Cyprus by several authors (summary in Benda et al., 2011).
The fauna of Streblidae is represented by a single species, which was confirmed for the first time on both islands.
