Postcoxal line on ventrite 1 short, evenly rounded, extended slightly more than ½ distance to apical margin of ventrite. Apex of ventrite 5 arcuate. Genitalia with basal lobe slightly longer than paramere, slender, slightly divergent in basal 2/5 and then narrowed to rounded apex, in lateral view lobe flattened; paramere wide at base, narrowed to rounded apex, dorsal margin without serrations (Fig. 21–22); sipho slender throughout to narrow, filamentous apex (Fig. 23).
