The Bembicidae are a diverse group of apoid wasps whose members commonly possess an oblique carina near the rear corners of the scutum and/or two spurs on the mid tibiae (Bohart & Menke 1976).

Characters (from Bohart & Menke 1976, as Nyssoninae excluding Mellinus): Eyes with inner margins essentially parallel or converging below, if converging above then at least hindocelli somewhat distorted and scar-like. Mandible not notched nor toothed externoventrally, inner subteeth, when present, associated with apical tooth; mandible socket open; palpal formub usually 6-4. Scutum without complete notauli; an oblique scutal carina often present. Episternal sulcus present or absent, sometimes forming a continuous arc with scrobal sulcus (episternal-scrobal sulcus); omaulus usually present. Midtibia with two apical spurs (sometimes one or none), claws simple, midcoxae usually essentially contiguous, plantulae present or absent. Propodeal sternite absent. Forewing with two or three submarginal cells of which II usually receives at least one recurrent vein, three discoidal cells present. Hindwing media diverging before, at or beyond cu-a; jugal lobe usually small, rarely absent, at most half as long as anal area. Gaster usually sessile but peduncle, when present, made up of both tergum and sternum; male gaster with six or seven exposed terga; sternum VIII often modified and largely or entirely concealed; male genitalia usually with volsella differentiated into cuspis and digitus.
