Type Material. Holotype, male, labeled: ‘[oval label with green color on upper side, blank] / [underlined in yellow] Sarawak, [/underlined in yellow] Borneo, Wallace. / Pascoe Coll. 93–60. / Hemipeplus [something illegible] / Hemipeplus klematanicus, Gestro Determined from description. G.J.A. / [green label] ♂ / [red label] HOLOTYPE ♂ Hemipeplus pseudoklematanicus 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 species’ close morphological resemblance to Hemipeplus klematanicus.
Diagnosis. Hemipeplus pseudoklematanicus sp. nov. can be distinguished from the similar-appearing H. klematanicus (Fig. 46) by its rounded, instead of acutely pointed, temples, wider pronotum, and paler color. Hemipeplus pseudoklematanicus sp. nov. has the following diagnostic features: temples short and rounded; scape moniliform, apically dilated; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum subcordiform; anterior emargination distinct; anterior half slightly wider than posterior half; pronotal pad distinct; anterior pronotal angles rounded, posterior angles obtuse; pronotal lobe slightly present without median notch; body long; elytra slightly convex; color dull, rufotestaceous, not nearly as dark as H. klematanicus, pronotum lighter; distribution: Malaysia (Sarawak).
Description. Measurements (in mm)—GHW: 0.65; HL: 0.65; AL: 1.23; GPW: 0.75; PL: 0.60; GEW: 0.93; EL: 2.84; TL: 4.09.
Head (Fig. 48B) about as long as wide (GHW/HL: 1); eyes large (longer than scape + pedicel), moderately wide and moderately convex; temples short and rounded; occiput with strongly raised areas; antennae subequal to head and pronotum length combined; antennal scape moniliform, apically dilated; pedicel small moniliform; antennomere III more elongate and apically dilated; IV shorter and moniliform, apically dilated; V moniliform, larger, apically dilated; VI–X subtriangular or bowl shaped, each wider than the next; XI subpyriform with apex narrowed after the notch; lateral mandibular tooth unobservable in the specimen. Pronotum (Fig. 48B) wide (GPW/PL: 1.25); anterior margin with distinct emargination; anterolateral angles rounded, produced; lateral margins moderately sinuate; posterior half contracted; posterolateral angles obtuse; pronotal lobe slight without median notch; pronotal pad distinct (Fig. 48C); pronotal pits deep with moderate grooves. Scutellar shield transverse, subpentagonal, about twice as wide as long. Ventral surface. Prosternal process short, not extending posterior of procoxae; hypomeral edges not very close together unlike in H. klematanicus, and well separated; mesosternal process narrow and linear. Elytra (Fig. 48A) long (EL/GEW: 3.05), slightly convex; vestiture short and dense; apical patch broad and rufous. Color dull, rufotestaceous, pronotum lighter.
Male Genitalia (Figs 48D–F). (Tegmen length = 0.29 mm) Lobe of basale short and apically pointed; shoulders obtusely angled with moderate slant; parameres arcuate apically with corners of apices darker which is because of an additional lobe that extends behind them (visible on lateral view) (Fig. 48F); apices thick and blunt; penis longer than tegmen, shrunk at the halfway point and apically.
Remarks. Hemipeplus pseudoklematanicus sp. nov. superficially resembles H. klematanicus (Fig. 46); both species are sympatric in Malaysia (Sarawak).
