Nyctiophylax (Paranyctiophylax) flavus , new species group

Species in this group have elongate, monolobed gonopods, each with a variously developed ventrobasal “elbow.” This gonopod structure is accompanied with downwardly curving ventral paraproctal processes, and the absence of sclerotization or completely absence of the dorsal paraproctal processes. Sternite IX is frequently produced into a ventroapical, median lobe of various lengths. The phallic organ has usually a long and slender, spine-like phallic apodeme or pseudoapodeme anterodorsally on the phallotheca (phallobase).
