Cosmopelma dentatum Fischel, 1927

Cosmopelma dentata Fischel, 1927:69; Roewer, 1942:220; Raven, 1986:52. Cosmopelma dentatum: World Spider Catalog, 2016.

Remarks. Cosmopelma dentatum was described by Fischel (1927) based on a male specimen from Venezuela. Raven (1986) suggested that this species, whose type is lost, should be excluded from the genus based on the absence of a clypeus and the different abdominal pattern.

Fischel (1927) stated that the described specimen had all characteristics found in Cosmopelma, except for the presence of teeth on the claws. However, other characters in the original description do not correspond to what we see in Cosmopelma, such as the uniform dark brown color, the labium being longer than wide and indented forward, and the recurved fovea. Furthermore, there was no mention of the distinctive spiky cuspules.

Thus, it is very likely that the lost type did not belong to Cosmopelma. The characters and the figures in Fischel (1927) suggest that the specimen could potentially belong to the cyrtaucheniid genus Fufius Simon, 1888. Therefore, this species is hereby considered as nomen dubium in Fufius.
