Diagnosis. Gena usually entirely covered with black setulae. Thorax with 3 postsutural dorsocentral setae. Wing-vein R 1 often setose dorsally. Male hind trochanter usually with a brush of more or less tightly-spaced spine-like setae ventrally. Female mid-femoral organ, if present, situated in apical half. Abdominal tergite 3 with or without mediomarginal setae. Male terminalia: sternite 5 with brushes of stout bristles along posterior margin; epandrium often red, with a gently curving dorsal outline when viewed in profile; epandrium and protandrial segment more or less elongate, usually longer than high; cerci flattened dorsally or with a dorsal excavation; basiphallus long; vesica usually reduced, scale-like, never bilobed; apical processes of harpes often long, flattened (but may be short or extremely short, seemingly absent); juxta distinct from rest of distiphallus, sometimes elongate, longitudinally undivided or divided, with or without membranous basal appendages. Female terminalia: abdominal tergite 6 red, brown or black, undivided or divided into two hemitergites; vaginal plate present anterior to hypoproct; spermathecae usually small, globular.
