Trachusoides Michener and Griswold, 1994: 324

Type species: Trachusoides simplex Michener & Griswold 1994 Diagnosis. Female is unique among Anthidiini in the simple rather than cleft or toothed mid and hind tarsal claws. It shares with Apianthidium Pasteels and Trachusa Panzer the large megachiliform body and the tendency for reduced maculations. Unusual is the almost complete lack of carinae on the head and mesosoma (carinae limited to pronotal lobe). Almost all Anthidiini are heavily adorned with such carinae. In addition to characters differentiating Trachusoides from Apianthidium and Trachusa as presented in Michener (2007), the hind tibial spurs are longer, half the length of the hind basitarsus, and distinctly serrate ( Fig. 3 ).
