Remarks. Only four male specimens including the holotype (Fig. 16 A) were located in collections (OSAC, FMNH) for examination. My attempts to collect more individuals of this species around the known localities in early June 2015 were unsuccessful. The flagellum of the male genitalia ends in a large, trilobed, sclerotized club (Fig. 16 B).
