Elaphropeza biuncinata group

Members of this group are characterised by the following combination of characters: male genitalia with one rod-shaped apodeme ( Fig. 111 ); phallus in the form of a long tight coil ( Fig. 114 ); a long upturned bristle present just above fore coxa ( Fig. 6 ); abdominal tergites 3, 4 and 5 with squamiform setae; abdominal glands present between tergites 3-4 and 4-5. Additionally, in species of this group the hind tibia lacks anterodorsal bristles (except E. combinata sp. nov.), cerci are separated ( Fig. 111 ) and the right surstylus is very prominent ( Figs 111 ). In females, sclerites of abdominal segment 8 are fused antero-laterally and sternite 8 is not folded apically ( Fig. 115 ).
