The subgenus Prosopisteron of the genus Hylaeus includes small, relatively generalised bees with broad apical lobes on the seventh sternum in males (Michener 1965).

Characters (from Michener 1965): Mandibles only rarely with weak third or fourth tooth in female; interantennal distance greater than clypeo-ocular distance; subantennal sutures shorter than to two times as long as diameter of antennal socket; middle segments of male flagellum usually less than twice as long as broad. Claws with prongs usually parallel; stigma large, two-thirds to three-fourths as long as, or nearly as long as, costal margin of marginal cell; free part of marginal cell longer, usually twice as long, as rest; apex of cell usually very near wing margin; distance from apex of cell to wing tip equal to or less than length of free part of cell; second submarginal cell usually half as long as first or less, receiving both recurrent veins or the first received near end of first submarginal cell; propodeum with horizontal area shorter than vertical, triangle usually with one-fourth to one-half of its length on vertical surface; horizontal surface rounded onto vertical surface, usually dull but not areolate or carinate and without carina or sharp angle separating dorsal from horizontal surfaces. Second tergum with fovea usually absent or punctiform; gradulus of second tergum usually transverse; seventh sternum of male with four apical lobes, at least one pair of them broad and with hairs; eighth sternum with median process usually notched at apex, occasionally bifid or simple.
