Type Material. Holotype, male, labeled: ‘[underlined in green] BRAZIL: Am. [/underlined in green] Reserva Ducke 26km NE Manaus Barbosa, M.G. V / Plot A, Malaise 4 July 1995 / BMNH {E} 2003-84 / 84.1 / [green label] ♂ / [red label] HOLOTYPE ♂ Hemipeplus brasiliensis KC & Pollock’, in BMNH.
Derivation of Specific Epithet. The specific name (adjective in the nominative case, in gender agreement with substantive) is given in allusion to the type locality of the holotype, i.e., Brazil.
Diagnosis. Hemipeplus brasiliensis sp. nov. can be distinguished from the similar-appearing H. angustipennis (Fig. 13) by its larger, more convex eyes, less produced anterolateral pronotal angles, and paler head and pronotum. Hemipeplus brasiliensis sp. nov. has the following diagnostic features: temples prominent, posteriorly rounded; scape short, moniliform; eyes large (longer than scape + pedicel), shallow and less convex; pronotum subcordiform, slightly widened anteriorly with a shallow anterior emargination; anterolateral angles moderately produced, broadly rounded; pronotal pad present; posterolateral angles square, rounded; pronotal lobe slight but visible with median notch; elytra more or less flat; color rufotestaceous with portions of elytra slightly piceous; distribution: Brazil (Amazonas).

Head (Fig. 12B) as long as wide, (GHW/HL: 1.00); eyes large (as long as scape + pedicel), shallow and less convex; temples wide and posteriorly rounded, about 1/3 length of eye, bulged outward; occiput with raised areas; antennae shorter than head and pronotum length combined; antennal scape short, moniliform and produced externally on one side; pedicel small moniliform; antennomere III more elongate and apically dilated; IV short and moniliform; V slightly larger, apically dilated; VI–X subtriangular or bowl shaped, each wider than the next; XI subpyriform with apex narrowed after median notch; lateral mandibular tooth absent. Pronotum (Fig. 12B) wide (GPW/PL: 1.27); anterior margin with moderate emargination; anterolateral angles broadly rounded, slightly produced; lateral margins sinuate; posterior half slightly contracted than apical half; posterolateral angles square and rounded, very slightly produced; pronotal lobe slight with median notch; pronotal pad (Fig. 12C) present but narrow; pronotal pits deep with oval grooves. Scutellar shield subhexagonal, transverse, not twice as wide as long. Elytra (Fig. 12A) elongate (EL/GEW: 4.00) and flat; vestiture very short but dense; apical patch long and piceous. Ventral surface. Prosternal process short, not extending to the posterior of procoxae; hypomeral edges broadly separated; mesosternal process narrow and linear. Color rufotestaceous head and pronotum, with portions of elytra slightly piceous.
Male Genitalia (Figs 12D–F). (Tegmen length = 0.35 mm (n = 1)) Lobe of basale short, slender with rounded apex; shoulders obtusely angled, fairly slanted; parameres almost straight, slightly narrowed near the bases of apicale; apices of parameres thinner than the bases with sharp thin tips; penis shorter than tegmen.
Geographical Distribution (Fig. 62). Brazil (Amazonas).
Natural History. The holotype of H. brasiliensis sp. nov. was collected in a malaise trap.
