“…1–5 ). Michanthidium was described by Urban (1993) as Gnathanthidium , a name she subsequently replaced to avoid the junior homonymy with the African Gnathanthidium Pasteels ( Urban 1995 ). The two species currently known in Michanthidium , Hypanthidioides sakagamii (Urban) and Hypanthidioides ferrugineus (Urban), occur in southern Brazil and northern Argentina; the latter is known only from the female.…”

As part of ongoing investigations on anthidiine bees, the type of Anthidium albitarse Friese was found to be conspecific with one of the two species of the small resin bees Hypanthidioides subgenus Michanthidium. The new combination, Hypanthidioides (Michanthidium) albitarsis, is the oldest name, resulting in Gnathanthidium sakagamii Urban as a new junior synonym. The previously unknown male of the second species, Hypanthidioides ferrugineus, is described and figured, including the genitalic structure and associated sterna. Males and females of Hypanthidioides ferrugineus have been collected from flowers of Cuphea sp. (Lythraceae).

“… Michanthidium Urban, 1995 is an exclusively Neotropical anthidiine genus, according to the classification proposed by Urban and Moure (2007) , although it is considered by Michener (2007) as a subgenus of Hypanthidioides Moure, 1947, along with nine other subgenera. Two species of Michanthidium , Michanthidium sakagamii (Urban)and Michanthidium ferrugineum (Urban) were originally described in Gnathanthidium Urban, 1993 and subsequently renamed by Urban (1995) , because it was a junior homonym of Gnathanthidium Pas teels, 1969. In a recent paper, Gonzalez and Griswold (2011) proposed a new combination, Hypanthidioides (Michanthidium) albitarsis (Friese, 1916)(here considered Michanthidium albitarse ) as the oldest name, resulting in Michanthidium sakagamii as a junior synonym.…”

The Anthidiini is a highly diverse tribe of bees with approximately 700 described species worldwide, of which about 350 occur in the Neotropical region. However, the phylogenetic relationships within the Neotropical lineage are poorly understood and the generic limits of these clades are still controversial, with different proposals of classification. Therefore, we carried out a phylogenetic study to investigate the monophyly of Neotropical taxa, to understand the relationships among Neotropical genera, and to propose a classification congruent with the evolution of the group. We performed parsimony-based morphological analyses using a matrix of 204 characters from adults of 83 species (79 terminal taxa of Anthidiini and four outgroup taxa). The results provide strong support for the monophyly of the tribe, despite a representation biased towards the Neotropical taxa. The monophyly of a large group containing only species from Neotropical genera is also supported. The latter group is divided into six main clades, one of them composed of only cleptoparasitic taxa (Austrostelis, Hoplostelis, Melostelis and Rhynostelis). The morphological characters assembled here allowed scrutiny of the genus-level classification of the Neotropical clade and may be useful for future phylogenetic studies involving the Anthidiini from other biogeographic regions.
