Tmesiphantes crassifemur is a species of theraphosine theraphosid spider. It is native to Argentina.[1]

Taxonomic history

[edit]

In 1960, Berta Gerschman de Pikelin and Rita Schiapelli described this species as Melloleitaoina crassifemur. In 1993, Gunter Schmidt transferred the species to Dryptopelma, but this was rejected by Fernando Pérez-Miles in 1996. In 2019, the species was transferred to Tmesiphantes.[1]

Characteristics

[edit]

Tmesiphantes crassifemur is only known from the male. It is characterized by a very curved embolus without any triangular tooth. The prolateral inferior embolar keel is just as long as the prolateral superior and the apex of the embolus is widened.[2]
