Diagnosis. Hemipeplus klematanicus can be distinguished by its short, acutely pointed temples and acutely pointed posterior pronotal angles. Hemipeplus klematanicus has the following diagnostic features: temples short and acute angled; scape submoniliform; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum subcordiform; anterior emargination distinct; anterior half wider than posterior half; pronotal pad slight; anterior pronotal angles rounded, posterior angles sharply acute; pronotal lobe slightly present with faint median notch; body long; elytra slightly convex; color dull, rufotestaceous to rufopiceous, head and pronotum darker; distribution: Indonesia (Northern Sulawesi), Malaysia ( Sarawak, Selangor), Thailand (Phang Nga).

Re-description. Measurements (in mm)—GHW: 0.50–0.64; HL: 0.48–0.62; AL: 0.85–1.05; GPW: 0.55–0.68;

PL: 0.43–0.58; GEW: 0.73–0.90; EL: 2.38–3.25; TL: 3.29–4.45.

Head (Fig. 46B) wide (GHW/HL: 1.03–1.04); eyes large (longer than scape + pedicel), moderately wide and moderately convex; temples short and acutely angled; occiput with raised areas; antennae slightly shorter than head and pronotum length combined; antennal scape submoniliform, apically dilated; pedicel small moniliform; antennomere III more elongate and apically dilated; IV shorter and moniliform, apically dilated; V–X subtriangular or bowl shaped, each wider than the next; XI subpyriform with apex narrowed after the notch; lateral mandibular tooth very short. Pronotum (Fig. 46B) wide (GPW/PL: 1.17–1.28); anterior margin with distinct emargination; anterolateral angles rounded, produced; lateral margins sinuate; posterior half slightly contracted; posterolateral angles acutely pointed; pronotal lobe slight with faint median notch; pronotal pad (Fig. 46C) slight; pronotal pits moderately deep with moderate grooves. Scutellar shield transverse, subhexagonal, about twice as wide as long. Elytra (Fig. 46A) long (EL/GEW: 3.26–3.61), slightly convex; vestiture long and dense; apical patch long and more or less darker than elytra. Ventral surface. Prosternal process short, not extending posterior of procoxae; hypomeral edges very close together, only narrowly separated; mesosternal process narrow and linear. Color dull, rufotestaceous to rufopiceous, head and pronotum darker; ventrally unevenly rufous with edges of sternal plates darker; palpi and tarsi paler.

Male Genitalia (Figs 46D–F). (Tegmen length = 0.30 mm (n = 1)) Lobe of basale long and slender; shoulders obtusely angled with moderate slant; parameres feebly arcuate at apices with tips thick and blunt; penis longer than tegmen with narrowed apex.

Variation. The specimen of H. klematanicus from Thailand is much smaller than other specimens examined.

Geographical Distribution (Fig. 65). Indonesia (Northern Sulawesi) (new country record), Malaysia ( Sarawak, Selangor), Thailand (Phang Nga) (new country record).

Natural History. According to specimen label data, H. klematanicus has been found in unopened fronds of Nypa fruticans ( Arecaceae ) and adults have been collected from malaise traps, flight interception trap, carrion baited trap in lowland forest, and light trap.
