Distinguished from occidentalis by the relatively longer surstylus (apical width/total length 0.40) (fig. 6), and by the long paraphysis in lateral view (0.54 greatest width/length). Separated from orientalis by having a wider interocular distance; cheek deeper; abdominal sternites (males) rectangular; abdominal pleural membrane with setulae more numberous in both sexes; female tergites smaller.
