Interpretive Summary: The bee subfamily Oxaeinae, found only in the Americas, is still poorly known. A new subgenus, Alloxaea, is described for a distinctive new species (Oxaea brevipalpis). The first key to identify many of the species of Oxaea is provided. The relationships of these ground nesting bees are discussed, with Mesoxaea and Notoxaea recognized as distinct groups worthy of generic status.

Technical Abstract: 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.
