A revision of Physotarsus Townes (Hymenoptera: Ichneumonidae: Ctenopelmatinae), with description of 18 new species Author Zhaurova, Kira Author Wharton, Robert text Zootaxa 2009 2207 1 52 journal article 10.5281/zenodo.189753 96bfbb6b-3a6e-4bbb-8985-e57129b08480 1175-5326 189753 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.
