Male pygofer in lateral aspect with broad, curved, moderately long process arising from 

 caudoventral margin, process with lateral margins nearly equidistant throughout with a small, 

 subapical aperture on the outer lateral margin, apex with a small tooth; aedeagus in lateral 

 aspect with dorsal appendage broad at basal half, becoming narrowly attenuated at apical 

 half, slightly constricted subapically and curved dorsoposteriorly ; dorsal appendage without 

 spines or flanges, dorsal margins expanded in dorsal view; ventral appendage long, narrow, 

 tube-like, somewhat swollen apically, slightly exceeding apex of dorsal appendage; gonopore 

 apical; connective Y-shaped; style clawed apically; plate with distal segment elongate, dorsal 

 margin expanded medially. 



Female seventh sternum with posterior margin produced medially.

Biology. Unknown. 



Remarks. This species is similar in male genital characteristics to metallica 

 but can be separated from that species by the unique colour patterns and sexual 

 dimorphism between the sexes and the prevalence of the aperture on the subapical 

 outer lateral margin of the pygofer process.
