Male genitalia

( Figure 6A View Figure 6 ). Uncus long and slender, apex acute. Gnathos with anterior margin arched backward medially, forming a small process, a pair of strongly sclerotized long thorn-like processes arising from lateral side of the median process. Valva elongate rectangular, apex almost truncate; costa gently arched beyond middle; dorsoproximal process large, somewhat hammer-like, setose. Sacculus narrow, thinned distally, with very narrow, sclerotized edge along median portion dorsally. Juxta shield-like, lateral lobe long and narrowed. Aedeagus stout, nearly half length of valva, distal two-fifths obliquely truncate.

Diagnosis

This species is represented by the gnathos arched backward and forming a median process anteriorly, a pair of strongly sclerotized long thorn-like processes arising from the lateral side of the median process, and the valva elongate rectangular and truncate at apex.
