Bat fly

Ace Amarga:(Philippine Bat Champions) suggested genus Brachytarsina and identification of it up to species level requires wing venation examination.

Bat flies are nominally divided into two cosmopolitan families, Streblidae and Nycteribiidae, but recent phylogenetic studies suggest these are not natural groups (Dittmar et al. 2006). Nycteribiids (275 species) are more speciose in the Eastern Hemisphere, whereas the streblids (227 species) are richer in the Western... Although all nycteribiids are wingless (Fig. 1b), most (220 species or 97%) streblids possess wings, but not all these possess functional, macropterous wings (Figs. 1a, d). -http://fm1.fieldmuseum.org/aa/Files/patterso/Dick___Patterson_2006_MicromammalsMacroparasites.pdf

however, I just found this: Nycteribiidae are wingless, have reduced eyes, and a spiderlike appearance. This is because their legs actually insert dorsally into the thorax. Streblidae have varying degrees of wing reduction, and appear more like a regular fly. They also have reduced eyes. -http://www.bat-flies.buffalo.edu/general_info.html

Thanks jumpingspiderman, I now think it's a bat fly but I'm leaning towards Nycteribiidae because: Streblidae ... are generally considered to be New World species, while Nycteribiidae ... are mostly found in the Old World. -http://batflies.wordpress.com/about/

Thanks Chun, I'll look into Bat Flies... but first it's bedtime! http://batflies.wordpress.com/about/ https://sites.google.com/a/fieldmuseum.org/bruce-pattersons-lab/Home/research-areas/bat---bat-fly-coevolution http://en.wikipedia.org/wiki/Streblidae http://en.wikipedia.org/wiki/Nycteribiidae
