Tribe Anthidiini Ashmead, 1899

Anthidiine bees are easily distinguished from other Megachilinae by having mostly conspicuous white, yellow or red integumental markings on various tagma and scarce pubescence. Additionally, the members of the tribe can also be recognized by the shape of the female mandible, usually wider apically, with three or more teeth (except bidentate mandible is some species); anterior portion of mesepisternum well-marked, and clearly separated from the lateral portion by a sharp angle or crest (omaulus); a small pterostigma, less than twice as long as broad; second recurrent vein placed usually distal or posterior to the second submarginal crossvein; apical margin of the malus and velum contoured by hairs and, tarsal claw of the female being cleft or with an inner tooth (except in Trachusoides Michener and Griswold ).

The main lineages recovered in the study of Litman et al. (2016), and recognized by them as groups, are here accommodated in a subtribal classification system. The proposed classification is listed below and a more complete treatment of this classification system, with subtribal synopsis, diagnosis, and identification key will be presented in a forthcoming contribution.

1. Anthidiina Ashmead, 1899 (Type genus: Anthidium Fabricius, 1804 ) for the Anthidium group;

2. Dianthidiina Moure, 1947 (Type genus:Dianthidum Cockerell, 1900) for the Dianthidium group;

3. Epanthidiina subtrib. nov. (Type genus: Epanthidium Moure, 1947 ) for the Anthodioctes group;

4. Stelidina Schenck, 1860 (Type genus: Stelis Panzer, 1806 ) for the Stelis group;

5. Trachusina Robertson, 1904 (Type genus: Trachusa Panzer, 1804 ) for the Trachusa group.
