A new subgenus and species of Oxaea from Ecuador (Hymenoptera: Andrenidae)

Resumen

A new subgenus and species of Oxaea KLUG (Andrenidae: Oxaeinae) is described and figured from western Ecuador. Oxaea ( Alloxaea ) brevipalpis subg. n. et sp. n., is noteworthy for the retention of maxillary palpi (3-segmented), absence of metallic integumental coloration, and contrasting notal pubescence. A preliminary key to the species of Oxaea , exclusive of the flavescens group, is provided as an aid to identification as well as a stimulus for future research on the genus. Mesoxaea and Notoxaea are reinstated as genera distinct from Protoxaea.
