Abstract

URBAN, Danúncia. Considerations on Anthidulum Michener stat.n. and Dicranthidium Moure & Urban, stat.n. and descriptions of new species (Hymenoptera, Megachilidae). Rev. Bras. Zool. [online]. 1992, vol.9, n.1-2, pp. 11-28. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751992000100004.

A comparative study of some characters as: the lenght of the mesepisternal carina (almost complete or short), the shape of the scutellum (flattened or bilobed), and only in the male: the shape of the distal terga and of the sterna (normal or with some sterna hidden) and the lenght of the basal articles of the flagellum (short or longer than their diameter) resulted in distinguishing Anthidulum from Dicranthidium as good genera separated from Hypanthidioides Moure. Seven new species are described: Anthidulum christinae, sp.n. from Muzo, Colômbia; Anthidulum mourei, sp.n. from Ponta Grossa, PR, Brasil; Anthidulum cavichiolii, sp.n. from Cáceres, MT, Brasil: Anthidulum zanolae, sp.n. from Araxá, MG, Brasil; Dicranthidium luciae, sp.n. from Maracás, BA, Brasil; Dicranthidium soniae, sp.n. from Rep.R Grande, GB, Brasil and Dicranthidium insulare. sp.n. from San Rafael, Trinidad. Keys for the identification of the species of Anthidulum and Dicranthidium are included.

Keywords : Anthidulum; Dicranthidium; Megachilidae; Hymenoptera.
