(Figs 58, 65)

Type Material. Holotype, male, labeled: ‘[E. Malaysia] 16 miles point from Keningau Sabah, Is. Borneo 9.iii.1993, T Ueno leg. / [green label] ♂ / [red label] HOLOTYPE ♂ Hemipeplus saymyname KC & Pollock’, in BPBM. Ten paratypes: 9 specimens, 1 female, 8 sex unknown, labeled same as holotype, in DAPC; 1 specimen, male, labeled: ‘ SABAH: Mt. Kinabalu 1550-1650 m, 23.V.1987 Burckhardt-Löbl’, in MHNG .

Derivation of Specific Epithet. The specific name (noun in apposition) is given in allusion to the iconic phrase ‘Say my name’ from the popular TV series ‘Breaking Bad’.

Diagnosis. Hemipeplus saymyname sp. nov. can be distinguished from the similar-appearing H. craigi sp. nov. (Fig. 57) by its elytra usually suffused in light piceous shade, parameres of male genitalia much thinner, penis and lobe of basale longer. Hemipeplus saymyname sp. nov. has the following diagnostic features: temples short and roundish; scape short and moniliform; eyes moderately large (just as long as scape + pedicel), moderately wide and moderately convex; pronotum subcordiform; anterior emargination moderate but distinct; anterior half wider than posterior half; pronotal pad moderately present; anterior pronotal angles rounded and produced; posterior angles obtuse, rounded; pronotal lobe indistinct with faint median notch; body long; elytra slightly convex; color dull, rufous with most of the elytra suffused in piceous shade to uniformly rufotestaceous; distribution: Malaysia (Sabah).

Description. Measurements (in mm)—GHW: 0.55–0.62; HL: 0.52–0.60; AL: 0.85–0.95; GPW: 0.55–0.63; PL: 0.43–0.53; GEW: 0.70–0.87; EL: 2.70–3.34; TL: 3.65–4.47.

Head (Fig. 58B) wide (GHW/HL: 1.03–1.06); eyes moderately large (just as long as scape + pedicel), moderately wide and moderately convex; temples short and roundish; occiput with strongly raised areas; antennae shorter than head and pronotum length combined; antennal scape short, moniliform, apically dilated; pedicel small moniliform; antennomere III more elongate and apically dilated; IV small, moniliform; V larger, moniliform, apically dilated; VI–X subtriangular or bowl shaped, each wider than the next; XI subpyriform with apex narrowed after the notch; lateral mandibular tooth absent. Pronotum (Fig. 58B) wide (GPW/PL: 1.19–1.28), subcordiform; anterior margin with moderate emargination; anterolateral angles rounded, produced; lateral margins sinuate; posterior half contracted; posterolateral angles obtuse to square, rounded; pronotal lobe very faint with a hint of median notch; pronotal pad (Fig. 58C) narrow, but distinct; pronotal pits shallow without grooves. Scutellar shield transverse, subhexagonal, about twice as wide as long. Elytra (Fig. 58A) long (EL/GEW: 3.84–3.86), slightly convex; vestiture moderately long and dense; apical patch long and piceous, appears faint when in piceous elytra. Ventral surface. Prosternal process short, not extending posterior of procoxae; hypomeral edges very narrowly separated to less so; mesosternal process narrow and linear. Color rufous with most of the elytra usually suffused in piceous shade; antennomeres III–basal XI usually darker; color uniformly rufotestaceous in the specimen from Mt. Kinabalu; ventrally inner edges of prosternum and hypomeral edges darker; abdominal sternites slightly darker; rest is uniformly rufous–rufotestaceous; palpi and legs lighter in some specimens.

Male genitalia dorsal view without spiculum gastrale; E. Tegmen dorsal view (with scale bar); F. Tegmen lateral view with one paramere removed.

Male Genitalia (Figs 58D–F). (Tegmen length = 0.28 mm) Lobe of basale long and slender; shoulders obtusely angled, moderately slanted; apicale and basale with distinct suture; parameres slender, slightly arcuate near the apices, tips not sharp; penis wide, much longer than tegmen with narrowed apex.

Variation. As given in the description above, one specimen of H. saymyname sp. nov. has a uniformly brown body while all others have elytra with a piceous shade.
