Long Legged Fly. Dolichopodidae, Genus Condylostylus
size ranges from 1-9 mm in length. 31-35 species north of Mexico, but only three west of Rocky Mountains. Over 300 species worldwide, most of them in Central America and tropical South America.
The distinctive character of Condylostylus is a pair of setose mounds on the frons bearing the vertical setae. When present, wing markings in the form of two bands joined along the costa will distinguish Condylostylus from other American Sciapodinae. In addition, the following combination of typical, but not universal, characters can help ID the genus:
vertex deeply excavated
M distinctly forked (unforked in Mesorhaga)
frons usually with pale bristles in addition to black (usually only black in Sciapus)
setae of calypter usually black (usually pale in Sciapus)
scutellum with two pairs of bristles (outer pair reduced or absent in Sciapus)
In many species, vein M1 is more sharply curved towards the base of the wing than in other genera. If you read to this point and understood at least quarter of this stuff- congratulation, you are a much better entomologist that I am
