Leioproctus (Excolletes) Michener, 1965

This subgenus was erected by Michener (1965) for the species Leioproctus (Excolletes) impatellatus . No further species are included. Upon examination of more specimens it has been shown that although the female holotype has apparently simple claws, all other females examined have a small to moderate sized inner ramus. Even though the basitibial plate is not carinate marginally, it is indicated by shorter, darker, thicker hair. The other unusual characters found in this subgenus are the low position of the antennal bases on the head; fore wing with a nearly transverse basal vein and the female pygidial plate more or less spatulate.

Type species— Leioproctus (Excolletes) impatellatus Michener, 1965

Diagnosis — Small, dark bees with white metasomal hair bands in females, basitibial plate of female absent.
