Leioproctus (Exleycolletes) subgen.n.

This subgenus is erected for 7 species, 1 species was placed in Leioproctus (Lamprocolletes) by Michener 2007, 3 species placed in L. ( Leioproctus ) by Michener 1965, 1 species placed in Leioproctus (Microcolletes) by Michener, 1965 and 2 placed in L. ( Goniocolletes ) in 1965. They are small to moderate-sized, black bees and compared to other Leioproctus have a slender metasoma. Some of them have a low tubercle on the metanotum.

Type species— Paracolletes tuberculatus Cockerell, 1913b .

Description—Head Inner eye margins converging below antennal sockets; facial fovea vaguely indicated by change in surface texture; antennal sockets depressed; scape reaches median ocellus; apex of supraclypeal area sharply raised; epistomal suture distinct; malar space short and polished; both pairs of palps well sclerotised, extending beyond apices of glossa and maxillae; surface sculpture of dense punctures with smooth interspaces; females with long, whitish hair; males with dense hair, appressed on at least the lower paraocular area. Mesosoma — Surface sculpture of shallow, small punctures with smooth interspaces; metanotum with minute to moderate sized, median tubercle; propodeal triangle strongly sculptured. Wings hairy; stigma blunt, more than 0.5 x length of costal margin of marginal cell; apex of marginal cell separated from costa for very short distance; first recurrent vein enters second submarginal cell towards the base; jugal lobe of hind wing reaching beyond cu-a. Legs simple, female with hind basitibial plate sparsely covered in short, thick hairs; hind tibial scopa with open monopodally branched hairs; inner hind tibial spur with 5–10 moderate length, slender teeth. Metasoma— Slender; surface sculpture as for dorsal mesosoma; hair sparse; prepygidial fimbria dense, thick-haired; female pygidial plate strongly sculptured basally; males with bare median area on T7; S4 with long, thick fringe; S7 with complex lateral lobes; genitalia with gonoforceps with apices weakly sclerotised, ventral penis valves with a sclerotised ridge.
