Diagnosis. Hemipeplus bolivianus can be distinguished from the similar-appearing H. argentinus (Fig. 22) by its moniliform scape and shallower anterior emargination on the pronotum. Hemipeplus bolivianus has the following diagnostic features: temples moderately long, rounded; scape very short and moniliform; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum subcordiform, with shallow anterior emargination; punctures wider than in H. argentinus; anterior half more widened than posterior; anterolateral angles produced, broadly rounded; pronotal pad distinct; posterolateral angles obtuse, rounded; pronotal lobe indistinct with faint to no median notch; scutellar shield subhexagonal, transverse, twice as wide as long; body elongate; color uniformly rufotestaceous; elytra slightly convex; distribution: Bolivia, Brazil (Pollock 1999), Colombia?, Ecuador, Peru (Pollock 1999).
Male Genitalia (Figs 23. 1D–F, 23. 2D–F). (Tegmen length = 0.30–0.35 mm (n = 4)) Lobe of basale moderately long, thin, pin-like with rounded apex; shoulders almost straight, acutely angled; apicale and basale with distinct suture; parameres straight, diverging outward; apices of parameres straight, sharp and pointed; penis much longer than tegmen, slightly narrowed medially.
Variation. Some specimens have slightly deeper emargination on anterior pronotal margin; there is a slight median notch on truncate pronotal lobe of some specimens; parameres are longer in some specimens than others.
Remarks. Hemipeplus bolivianus is a widespread species in South America.
Geographical Distribution (Fig. 62). Bolivia, Brazil (Pollock 1999), Colombia?, Ecuador (new country record), Peru (Pollock 1999).
Natural History. Hemipeplus bolivianus is most likely associated with palms (Pollock 1999). According to specimen label data, adults have also been collected from UV light trap and malaise trap(s).
