Leioproctus (Charicolletes) subgen.n.

This new subgenus is erected for 4 species of Leioproctus , two of which are described as new and the other two species were previously placed by Michener (1965) in the subgenus Leioproctus (Nodocolletes) . They are separated from the latter by having impressed facial foveae, the jugal lobe of hind wing reaching cu-a and male genitalia.

Type species: Leioproctus elegans Smith, 1853

Description: Small to moderate-sized, hairy, strongly punctate bees. Head Ocellocular area flat; frontal line carinate on lower part of frons, absent on upper part of frons; inner eye margin slightly converging in females, strongly converging below antennal sockets in males; scape reaches median ocellus; apex of supraclypeal area raised; epistomal suture weak to moderately distinct; surface sculpture with very dense, sharply defined punctures with polished interspaces. Mesosoma Surface sculpture of scutum as for face, punctation less dense posteriomedially; median metasomal tubercle small to moderate size; propodeal triangle almost vertical, mostly polished. fore wings with pterostigma parallel sided, about 0.5 x length of costal marginal of marginal cell, apex of marginal cell blunt, not strongly divergent from costa; jugal lobe of hind wing reaching cu-a. Legs with fore tibial spur with several fine teeth on apex; female basitibial plate with thick, branched hairs; female inner hind tibial spur with several, stout teeth. Metasoma Surface sculpture as for mesosoma; covered in fine, short hairs; male T7 with polished median area not carinate laterally; females T5 with dense, prepygidial fimbria; pygidial plate broad, flat, with a few, irregular, longitudinal striae; female sterna with apical marginal band of long, hair, mostly simple with some branched laterally; male S3–4 with apical fringe. Genitalia with dorsal angle at least angulate, usually produced; apices of gonoforceps broad, rounded; volsellae with enlarged cusp and digitus, strongly toothed.
