Type species. Atelurius segmentatus Simon, 1901 , by original designation.

Revised diagnosis. Males of Atelurius can be identified by the short RvTA, totally covered by denticles ( Figs 61– 62 ). Males of Atelurius differ from those of Scoturius and Urupuyu by not having a bilobed RTA; differ from those of Hurius and Simonurius by having a sub-triangular RTA. Males of Atelurius differ from those of Admesturius by having a longer embolus and shorter RvTA. Females of Atelurius differ from those of other huriines by having longer copulatory ducts with the proximal section membranous ( Fig. 48 ) and poorly differentiated spermathecae.
