Diagnosis. Hemipeplus suturalis can be distinguished by its acutely pointed temples and pronotum without pronotal pad. Hemipeplus suturalis has the following diagnostic features: temples short and strongly acute; scape submoniliform and externally produced on one side; eyes moderately large (as long as scape + pedicel), wide and convex; pronotum wide, flat, and subcordiform with distinct emargination on anterior margin; anterior half wider than posterior half; anterolateral angles strongly produced, broadly rounded; pronotal pad absent; posterolateral margins subparallel; posterolateral angles obtuse; pronotal lobe not prominent/truncate and without median notch; scutellar shield subhexagonal, transverse, less than twice as wide as long; body short and flat; elytra more or less flat; color dark testaceous, shiny, pronotum piceous–rufopiceous, head rufous–rufopiceous; distribution: west-central Africa (Cameroon, Republic of the Congo, Uganda) (Pollock 1997).
Male Genitalia (Figs 30D–F). (Tegmen length = 0.50 mm (n = 1)) Lobe of basale extremely short, thick, and wide; shoulders very slanted and obtusely angled; apicale and basale with distinct suture; parameres very long and almost straight with minimum sinuation near basal half; apices very thin and sharp, directed inward; penis shorter than tegmen tapering toward apex.
Remarks. Hemipeplus suturalis resembles H. quadricollis and H. pseudoquadricollis from the New World except for the subcordiform pronotum.
Geographical Distribution (Fig. 63). West-central Africa (Cameroon, Democratic Republic of the Congo, Gabon, Republic of the Congo, Uganda) (Pollock 1997).
Natural History. According to specimen label data, adults of H. suturalis have been collected at mercury vapor light and in secondary forest.
