Physotarsus fabioi Gauld, 1997

Physotarsus fabioi Gauld, 1997: 199 . Holotype Ψ in INBio. Physotarsus fabioi: Yu & Horstmann 1997: 455 (catalog).

Diagnosis. Occipital and epicnemial carinae completely absent. Fore wing Cu1a distinctly longer than 2cu-a. Head, hind legs, and metasoma black. Mesosoma orange. Wings entirely fuscous.

Remarks. This species is known only from the female holotype. None of the first three character states listed in the diagnosis (complete absence of occipital and epicnemial carinae and short fore wing 2cu-a) is known in any other species of Physotarsus . More significantly, we were unable to detect any evidence of a tyloid on the first flagellomere. All members of the Scolobatini, to which Physotarsus belongs, possess a tyloid laterally on the first flagellomere (Gauld 1984, 1997; Zhaurova & Wharton 2009). The absence of a tyloid leads us to reject this species as a member of the genus Physotarsus, and from the Scolobatini . We can find no satisfactory place for fabioi and treat it as incertae sedis within the Ctenopelmatinae, with the suggestion that it represents an undescribed genus.
