Material examined.

Holotype. Male (LMBC, UPOL 001379), Sumatra, Jambi Kersik Tua, Gn. Kerinci, 19.-22. Jan. 2005, 1600-2200 m.

Diagnosis.

Platerodrilus luteus resembles in general appearance the syntopically occurring Platerodrilus robinsoni , but these species are distantly related according to the recovered molecular phylogeny (Fig. 1). The male of Platerodrilus luteus differs from similarly coloured Sumatran Platerodrilus in the very wide and broadly emarginate phallobase (Fig. 67).

Description.

Body black, head dark brown, pronotum and elytra orange; antennae, and legs dark brown to black (Fig. 8). Head small, antennal tubercles weak, eyes hemispherically prominent, frontal interocular distance 2.8 times maximum eye diameter. Antennae slender, compressed, densely pubescent, antennomere 3 1.5 times longer than antennomere 2. Pronotum transverse, 1.7 times wider than long, frontal angles inconspicuous, lateral margins slightly convex, posterior angles acute (Fig. 23). Elytra parallel-sided, 3.7 times longer than width at humeri, elytral costae weak, covered with dense pubescence. Male genitalia with curved phallus; parameres short, rounded, with slender membranous processes; phallobase wide, deeply emarginate (Fig. 67-68).
