Summary

Description

Basilia nana Theodor & Moscona 1954 ♀ (Diptera Hippoboscoidea Nycteribiidae Nycteribiinae Nycteribiini).

Basilia Miranda Ribeiro 1903: 121 (IT: 2) spp.

FLVOR of this species in IT. Cfr. notes¹ over the above image.

Nycteribiidae are highly host-specific, anautogenous holo-ectoparasites and vectors of more virulent endoparasites of bats. Basilia nana is the most common ectoparasitic insect within Myotis bechsteinii closed fission-fusion philopatric societies, with long generation times, congruent host-parasite phylogeography, low intraspecific genetic differentiation and high gene flow due to frequent parasite transmission; private allelic richness decrease from E-EU to W-EU indicates a post-glacial colonization from the Balkans as in M. bechsteinii. Basilia nana adults live ≯ 6 months. Every 9 days, depending only on internal cycles and larval development, adult ♀♀ temporarily leave their hosts to deposit in the nearby areas, even at unsuitable places if no appropriate surface is provided, one frost-intolerant adenotrophic larva, pupating immediately; tₑ ≮ 30d, and ≯ 457d if no host would be available any sooner.

NOTES:

1. TBL 1.8 mm. Anautogenous holoectoparasitic of Myotis bechsteinii. Specific diagnostic characters: Smaller than Basilia italica. Eyes pigmented, with at least 2 lenses. Tergal plate #2 distinctively square. Sternite #5 with 8-10 short spines.
