Belongs within: Hylaeinae.

The subgenus Rhodohylaeus of the genus Hylaeus is an Australian group of small, largely reddish bees with the mesepisternum more or less sharply divided between the smooth anterior and punctate lateral sections (Michener 1965).

Characters (from Michener 1965): Mandibles two- or in some cases three-toothed in females; distance between antennae two or more times clypeo-ocular distance; subantennal sutures one to one and one-half times as long as diameter of antennal socket; paraocular ridges present, occasionally carinate. Claws with prongs subparallel. Wings occasionally with large bare areas basally; stigma two-thirds to more than three-fourths as long as costal edge of marginal cell; free part of marginal cell one and one-half to two times as long as rest, as long as or slightly longer than distance from apex of cell to wing tip, apex of cell bent away from wing margin; second submarginal cell usually slightly more than half as long as first, receiving both recurrent veins or one or both may be interstitial; propodeum with dorsal surface one-half as long as to almost as long as vertical one (seen in profile), the two curving one onto the other or an angle between them; triangle large, one-third or rarely only about one-fourth of its length vertical, areolate with carinae which may be weak, surface often dull. Fovea of second tergum absent or punctiform, gradulus slightly recurved and usually exposed; seventh sternum with single pair of apical lobes provided with slender hairs; gonocoxites robust, blunt, with long hairs apically.
