Pseudepiphallus narrower in the middle, distal half spatulate with rounded ventral enlargement (dorsal view); dorsal margin slightly elevated distally (side view). Epi-ectophallic invagination exceeding moderately rami insertion and reaching anterior projection of endophallic sclerite (dorsal view). Rami very wide (side view), truncated anteriorly. Female. SGP hind margin shallowly concave ( Fig. 32 ). OVP apex without distinct space between dorsal and ventral valves ( Fig. 32 ).
