Diagnosis. Hemipeplus argentinus can be distinguished from the similar-appearing H. bolivianus (Figs 23.1, 23.2) by its slightly elongate scape and distinct anterior emargination on the pronotum. Hemipeplus argentinus has the following diagnostic features: temples moderately long, rounded; scape submoniliform, slightly elongate, apically dilated; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum subcordiform, with a deep anterior emargination, anterior half much more widened than posterior; anterolateral angles strongly produced, broadly rounded; pronotal pad distinct; posterolateral angles obtuse, rounded; pronotal lobe not very prominent but with a slight median notch; scutellar shield subhexagonal, transverse, about twice as wide as long; body elongate; elytra slightly convex; color rufous, dull; distribution: Argentina (Entre Ríos Province).
