Elaphropeza ephippiata group

Members of this group are characterised by the following combination of characters: two male genitalic rod-shaped apodemes (ventral and ejaculatory) present ( Fig. 119 ); phallus short; long upturned bristle just above fore coxa absent; abdominal tergites 4 and/or 5 with squamiform setae (rarely absent); abdominal glands present between tergites 4 and 5. Additionally, in species of this group the hind tibia bears usually 1-2 anterodorsal bristles (but with quite numerous exceptions) ( Fig. 122 ), cerci are usually fused to form a single lobe ( Fig. 123 ) and the right surstylus is usually not prominent. In females, sclerites of abdominal segment 8 ( Fig. 121 ) are separated (except in E. feminata sp. nov.) and sternite 8 is folded apically.
