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.
