). The specimens under description are assigned to this genus due to their broadhead, large reniform eyes with dorsomedial projection, short thorax (no longer than its height), narrow scutellum, short postnotum, three rounded sclerotized spermathecae, and peculiarities of venation (vein C long, reaching R4+5 tip; Sc not terminating in wing margin; R2+3 absent; R1 long, not thickened distally in female; R4+5 straight or only slightly curved down distally; bR4+5 and m-cu inclined to long wing axis; r-m, bM3+4 and m-cu aligned; r-m much longer than bM3+4; cell ba and bp not symmetrical; m-cu connecting Cu proximal to r-m; costal and radial veins, stem M and CuA, r-m, bM3+4 and m-cu thickened, other veins very thin and pale; wings without spots).
