level of eyes; ocelli small, situated anteriolaterally; eyes large, somewhat globular, occupying 

 about two-thirds entire dorsal area of head; pronotum very short, median length much less 

 than median length of crown, lateral angle slightly overlapping base of elytra, surface smooth ; 

 scutellum very short, median length less than median length of pronotum; elytra long and 

 narrow in male, short, somewhat subbrachypterous in female, portion of female pygofer and 

 ovipositor sheath extending beyond apex of elytra, clypeus elongate, very broad anteriorly, 

 narrowed posteriorly, broader medially near antennal sockets, without median longitudinal 

 carina, surface finely granulose throughout; clypellus with lateral margins expanded apically. 



Male pygofer is not described here because it was lost during dissection. Aedeagus in 

 lateral aspect with dorsal appendage very broad basally, becoming narrowly attenuated 

 subapically, apex very narrow and curved caudodorsally, without spines or flanges; ventral 

 appendage long, tube-like, slightly curved, apex reaching apex of dorsal appendage; gonopore 

 apical; connective Y-shaped; style very narrowly clawed apically; plate with distal segment 

 long, very narrow, about twice as long as wide, dorsal and ventral margins only slightly 

 expanded.
