Diagnosis. Hemipeplus dollmani can be distinguished by its small temples, distinct pronotal pad, and shiny, pale color. Hemipeplus dollmani has the following diagnostic features: temples short and indistinct, often barely noticeable; scape short and moniliform; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum short, slightly wide, and subcordiform with distinct emargination anteriorly and sinuation laterally, anterior half wider than posterior half with deep anterior emargination in center; anterolateral angles produced, rounded; pronotal pad very distinct, broad and setose; posterolateral angles obtuse, rounded; pronotal lobe indistinct without median notch; scutellar shield subhexagonal, transverse, about twice as wide as long; body narrow and long; elytra slightly convex; color pale, shiny; distribution: Africa between 7°N and 25°S ( Pollock 1997).

Male Genitalia (Figs 31D–F). (Tegmen length = 0.28 mm (n = 1)) Lobe of basale short, slender with rounded end; shoulders straight and rounded; apicale and basale subequal (excluding the basale lobe) with distinct suture; parameres long and about straight with slightly arcuate apices; apices thin and sharp; penis very wide and longer than tegmen, narrowed apically.

Variation. Temples are more distinct in some specimens of H. dollmani than others.

Remarks. Hemipeplus dollmani resembles H. australicus from Australia but has temples; it resembles H. labuanensis sp. nov. ( Malaysia) and H. sinensis sp. nov. ( China) but the pronotal pad is wider with denser setae.

Geographical Distribution (Fig. 63). Cameroon, Democratic Republic of the Congo, Gabon, Republic of the Congo, South Africa, Zambia, Zimbabwe [Africa between 7°N and 25°S] ( Pollock 1997) .

Natural History. According to specimen label data, H. dollmani is associated with Setaria lindenbergiana? (Nees) Stapf ( Poaceae ).
