Key to species of the subgenus Taeniomastix

1. Fore femur with 2–7 long posterodorsal setae ( fig. 3 , 9), mid femur with long and dense setae on anteroventral surface and large kidney-like femoral organ in distal one-third of femur; medioventral cape of femoral organ densely white microtrichose ( fig. 3 , 10–11). Scutellum with one pair of apical setae. Abdominal tergites with wide black pattern. ............................................................................................... E. pictiventris .

— Fore femur only with short posterodorsal setae not longer than its width, mid femur with short setae on anteroventral surface; femoral organ in female either oval, without white microtrichose parts, or absent. Scutellum with one or two pairs of apical setae. ................................................................................................. 2.

2. Scutellum with one pair of apical setae. Africa. .................................................................................................. 3.

— Scutellum usually with additional pair of subapical setae half as long as apical. Asia. (Males unknown.) ........... 4.

3. Postpronotal seta and anepisternal setae present; postpronotal lobe with 4–8 setulae. Female: midfemur with femoral organ (Korneyev, 2006 a: fig. 3 , 4). Oviscape on ventral side with numerous thickened setae (Korneyev, 2006 a: fig. 3 , 8). Nigeria, Democratic Republic of Congo. ....................................... E. spinifemur
