Leioproctus (Fragocolletes) subgen.n.

This small subgenus is for 2 species, Leioproctus (Fragocolletes) perminutus (which was previously placed in Leioproctus (Microcolletes )) and L. (F.) rutiliventris , a new species. This subgenus has an areolate basal area of the propodeal triangle, similar to that in L. (Protomorpha), the structure of the genitalia and seventh sternum among other characters exclude them from that subgenus.

Type species: Paracolletes perminutus Cockerell.

Diagnosis— Moderate to small non-metallic bees; strongly punctate with polished interspaces; facial foveae distinct not impressed; F1–F2 length less than width, F3–F11 length about equal to width; basal area of propodeal triangle aerolate; male T7 denudate medially; male S5 with short, dense apical fringe.

Description — Length ca. 5–10mm; hair mostly white, moderately dense, medium length. Head— Scape of male not reaching median ocellus; flagellum long; inner eye margins of males straight converging slightly below; female inner eye margin almost straight, slightly converging at upper and lower margins; clypeus shallowly rounded; labrum narrow, polished; malar space absent; palps moderately sclerotised, length of each palpal segment at least 2 x width. Mesosoma —Scutum and scutellum with dense, small strong punctures with polished interspaces; hair fine, moderate length, branched; lateral scutellum in females with short, dense, tuft of hair. Wings with marginal cell broad at apex, widely separated from margin; first recurrent vein enters second submarginal cell almost medially; stigma large about 0.6 x length of costal margin, broadly rounded; jugal lobe of hind wing reaches beyond cu-v; wings hairy; clear to slightly milky; basal vein of forewing strongly sloping. Legs with scopa white, darker around basitibial plate; inner hind tibial spur of female with four or five, long, thick, well spaced teeth; other spurs simple; hind tibial plate about a quarter length of tibia with thick black simple hair. Metasoma —Metasoma with small, dense punctures except on T1; female pygidial plate flat, broadly rounded apically, rough; female sterna with long, densely branched hair; male T7 hairless medially; S5 with a short, dense, apical fringe; S7 with large lobes.

Etymology— Fragosus is Latin for rough referring to the roughened propodeal triangle
