(modified from Londt 1986). Asiline flies displaying the following combination of characters. Head: Face plane, not gently convex; dorsal occipital macrosetae long, proclinate. Thorax: Mesonotum strongly humped; acrostichal setae long, well developed, tightly packed and arranged in a narrow strip; scutellum with a single pair of apical scutellar macrosetae; discal cell (1m2) of wing not markedly constricted at midlength (as in Synolcus Loew, 1858); male wing with costal region not markedly expanded (as in some Dasophrys Loew, 1858). Abdomen: Female ovipositor long (more than twice as long as broad in lateral aspect) and laterally compressed. Figure 1 illustrates a fairly typical male of the genus.
