Type Material. Holotype, female, labeled: ‘P.I.: LUZON CAMARINES SUR Mt. Isarog, Pili, 800-900m, 21.IV.’65 / H.M. Torrevillas Light Trap BISHOP MUSEUM /[light green label] BPBM / [blue label] ♀ /[red label] HOLOTYPE ♀ Hemipeplus luzonensis KC & Pollock’, in BPBM.
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 this species, i.e., Luzon, Philippines.
Diagnosis. Hemipeplus luzonensis sp. nov. can be distinguished from the similar-appearing H. joerebeccae sp. nov. (Fig. 44) by its relatively smaller eyes, wider pronotum, and paler color; it can be distinguished from the similar-appearing H. harkoneni sp. nov. by its short and angulate temples. Hemipeplus luzonensis sp. nov. has the following diagnostic features: temples very short and angulate; scape moniliform; eyes large (longer than scape + pedicel), moderately wide and moderately convex; pronotum subcordiform; anterior emargination deep and distinct; anterior half much wider than posterior half; pronotal pad narrow but distinct; anterior pronotal angles rounded and strongly produced; posterior angles obtuse, rounded; pronotal lobe very slight with faint median notch; body long; elytra more or less flat; color dull, uniformly rufotestaceous; distribution: Philippines (Luzon).

Description. Measurements (in mm)—GHW: 0.74; HL: 0.71; AL: 1.12; GPW: 0.87; PL: 0.70; GEW: 1.00; EL: 3.70; TL: 5.11.
Head (Fig. 45B) wide (GHW/HL: 1.04); eyes large (longer than scape + pedicel), moderately wide and moderately convex; temples very short, angulate; occiput with strongly raised areas; antennae shorter than head and pronotum length combined; antennal scape moniliform, apically dilated; pedicel small moniliform; antennomere III more elongate and apically dilated; IV small, submoniliform; V more elongate, apically dilated; VI–X subtriangular or bowl shaped, each wider than the next; XI subpyriform with apex narrowed after the notch; lateral mandibular tooth potentially absent. Pronotum (Fig. 45B) wide (GPW/PL: 1.24), subcordiform; anterior margin with deep and distinct emargination in the center; anterolateral angles rounded, strongly produced; lateral margins sinuate; posterior half contracted; posterolateral angles obtuse, rounded; pronotal lobe very faint with a hint of median notch; pronotal pad (Fig. 45C) narrow, but well distinct; pronotal pits deep with moderate grooves. Scutellar shield subhexagonal, flat posterior margin, transverse, twice as wide as long. Elytra (Fig. 45A) long (EL/GEW: 3.70), more or less flat; vestiture short and dense; apical patch long and slightly darker than elytra. Ventral surface. Prosternal process short, not extending posterior of procoxae; hypomeral edges fused; mesosternal process narrow and linear. Color dull, uniformly rufotestaceous.
Geographical Distribution (Fig. 65). Philippines (Luzon).
