Leioproctus fulvescens, copyright Jacob Littlejohn.

Belongs within: Colletidae.

Leioproctus is a diverse, albeit somewhat poorly defined, genus of bees found in Australasia and South America (Houston 2018).

Characters (from Houston 2018): Fore wing with two or three submarginal cells; stigma well developed, tapering apically to marginal vell well within marginal cell; facial foveae often absent (if present, broad and not or only slightly to moderately impressed); mandible usually long, slender, with two apical teeth, posterior tooth much the largest and longest; labrum usually at least twice as wide as long, typically with basal area elevated and with one or more transverse carinae; propodeum usually with sloping, subhorizontal basal zone.
