Genus Hapalopus Ausserer 1875

Type species

Hapalopus formosus Ausserer, 1875, by monotypy.

Diagnosis

Adapted from Pérez-Miles & Perafán (2020) and considering the drawings of Hapalopus formosus by Gerschman & Schiapelli (1973: 71, figs 79–84). The species of Hapalopus have a dotted or striped abdominal pattern. The males can be distinguished from males from other genera of Theraphosinae by this character combination: palpal bulb with globose tegulum; prolateral inferior keel (PI) projected with ring shape (except in H. lesleyae); ventral tegular projection (VP) with a keel (TK) (only in H. formosus, H. serrapelada, H. akroa sp. nov., and H. guidonae sp. nov.); retrolateral face of palpal tibia with a tubercular process (TP) or a field of spines; tibial apophysis with two convergent branches, fused at base with prolateral branch shorter and thicker than retrolateral. Females can be distinguished from other Tharaphosinae genera by spermathecae with single receptacle, well sclerotized or with two sclerotized receptacles fused at the base.
