Subgenital plate triangular, apex rounded with a few stout setae arranged submarginally. Connective Yshaped. Style with apophysis stout and long, exceeding subgenital plate, ventral margin transversely rugulose. Aedeagus large, compressed, with a pair of subapical processes directed cephaloventrad, a pair of apical processes curved anteriorly after traversing a short distance in line with shaft, gonopore on caudal margin between bases of apical processes; dorsal apodeme welldeveloped.
Female genitalia
:
Hind
margin medially concave, without a median lobe.

Remarks
: The male specimen was dissected earlier and it is likely that the paraphyses are missing(?). The aedeagus has both apical and subapical long processes. The species is only tentatively retained in the genus pending availability of more male specimens for a proper generic placement. For further comments see
