ABSTRACT
Pronotum quadrate to very transverse, mostly smaller than head, without anterior angles except in Palaestes, laterally margined, dentate or denticulate, nearly impunctate to densely punctate, disc mostly with depressions; prosternum broad, prosternal process moderate to relatively narrow; procoxal cavities narrowly separated, open posteriorly, with an anterolateral extension exposing trochantins; mesocoxal cavities open laterally; metasternum elongate; trochantins visible on pro-and mesocoxae; anterior coxae globose, middle coxae globose, hind coxae transverse; trochanters normal; femora pedunculate; tibiae slender, apical spurs small, subequal; tarsal formula 5-5-5 females, 5-5-4 males; protarsi on males with tarsomeres somewhat expanded laterally compared to those of female; claws simple; scutellum quadrate
to pentagonal; elytra confusedly punctate, not striate (vague longitudinal lines visible in some species do not appear to be surface structures); scutellary striole absent; epipleural fold complete; metendosternite of normal hylecetoid type (Crowson 1938); wing venation varies within family, but generally well-developed, with radial cell complete (not Pediacus), radial recurrent present (not Pediacus), medial radial vein complete or nearly so; six veins behind M4 Cu, anal lobe present or absent (Wilson 1930).
