Nests of bees of the anthidiine genus Ananthidium Urban (Hymenoptera, Apidae, Megachilinae)

“…Ananthidium Urban is a neotropical genus with two species, Ananthidium inerme (Friese, 1908) and Ananthidium dilmae Urban, 1992. The first species is known from Argentina and Paraguay while the second is known only from southern and southeastern Brazil.…”

“…The first species is known from Argentina and Paraguay while the second is known only from southern and southeastern Brazil. This small group was given genus status by Urban (1992) and Stange (1995) whereas Michener (2007) treated it as a subgenus of Epanthidium Moure, along with two other subgenera (Epanthidium and Carloticola Moure & Urban). A phylogenetic analysis of the tribe (Parizotto 2011) indicated that Ananthidium is not closely related to Epanthidium and is herein treated as a separate genus, according to the classification proposed by Urban and Moure (2007).…”
