Espécies novas de Eucerinae Neotropicais e notas sobre Dasyhalonia phaeoptera Moure & Michener (Hymenoptera, Anthophoridae)

Abstract

ABSTRACT. New species of neotropical Eucerinae and notes on Dasyhalonia phaeoptera Moure & Michener (Hymenoptera, Anthophoridae). Lophothygater aculeata sp.n., Lophothygater nigrita sp.n. and Pachysvastraflavofasciata sp.n. are described and the diagnosis ofthe female of Dasyhalonia phaeoptera is given.

A phylogenetic study of the Thygater‐Trichocerapis group and new scopes for the subgenera of Thygater Holmberg, (Hymenoptera, Apidae)

“…As species of Lophothygater were not available for this study, the genus was kept in the Thygater‐Trichocerapis group based on characters described in the literature (Moure & Michener, ; Michener, ), which include the group`s synapomorphies. The rare species of Lophothygater were treated in detail by Urban (, ), being known only from the Amazonian basin, in Brazil, and from the oriental portion of the Andes, in Colombia (González & Ospina, ; Urban et al , ). Extensive descriptions of the genus are given by Moure & Michener () and Urban ().…”

“…In the following section, the information on authorities, holotypes and synonymies follows Urban et al (), except when noted otherwise. The diagnoses in the following are partially based on the characters employed in the earlier phylogenetic analyses and, partially, on the descriptions and discussions by Moure & Michener (), Michener () and Urban (, ). Characters in italics are those recovered in the earlier analyses as unambiguous synapomorphies for the diagnosed taxa.…”
