Taxonomic Note. Although Pollock (1999) stated that the holotype is the middle specimen of three, the label indicates that the top specimen is the holotype. Therefore, we have given precedence to the holotype label over Pollock’s (1999) statement.

Type Material. Holotype, male, top specimen of three specimens on same pin, labeled: ‘ Republic Dominican Bani 19.1.1976 leg. J.S. Klapperich [underside of label] 4.11.1973 / SMNS / [green label] ♂ top / [red label] HOLOTYPE (top spec.) & paratypes Hemipeplus dominicensis , n. sp. D.A. Pollock’, in SMNS. Two paratypes, mounted on the same pin as the holotype, in SMNS .

Diagnosis. Hemipeplus dominicensis can be distinguished by its elongate scape, lack of temples, and uniformly rufotestaceous color. Hemipeplus dominicensis has the following diagnostic features: temples absent; scape elongate, widened apically; eyes large (as long as scape + pedicel), moderately wide and moderately convex; pronotum subcordiform with an indistinct but broad anterior emargination; anterolateral angles slightly produced, broadly rounded; pronotal pad present but less distinct; posterolateral angles obtusely rounded; pronotal lobe brief with indistinct median notch; scutellar shield subhexagonal, transverse, about twice as long as wide; elytra flat; color uniformly rufotestaceous, dull; distribution: Dominican Republic.

Male Genitalia (Figs 7D–F). (Tegmen length = 0.42 mm (n = 1)) Lobe of basale short, sharp, and thin; shoulders acutely pointed with an upward slant; apicale and basale without distinct suture; parameres sinuate with pointed apices; inner margin of parameres with a notch near halfway; penis subequal in length to tegmen; parameres laterally surrounded by sheath-like structures (hereafter referred to as lateral sheaths).

Remarks. Hemipeplus dominicensis is closely related to H. chaos ( USA, Mexico) and H. insularis ( Dominican Republic) owing to the presence of lateral sheaths surrounding the parameres.

Geographical Distribution (Fig. 61). Southern Dominican Republic.
