Diagnosis. This species is very distinctive by the arrangement of elytral pubescence combined with the presence of humeral elytral carina and the tubercles on basal abdominal ventrite in males.

Description (Holotype): Body form, color and pubescence as in Fig. 28View FIGURES 25 – 30. Head and eyes larger; eyes not protruding from head outline. Pronotum distinctly convergent apicad, widest at base, with sides convergent from base to apex in almost straight line; apical pronotal margin distinctly narrower than basal margin, deeply bisinuate, with obvious anterior pronotal lobe, not projecting beyond anterior pronotal angles; posterior angles acute; pronotal disk conspicuously convex, with deep, oval, prescutellar impression; lateral impressions absent; prehumerus long, extending beyond half the pronotal length, sharply costate, evenly arcuate, with apex distant from marginal carina (lateral view).

Elytra with short humeral carinae, faintly bichromatic, with black and green-black pattern combined with white and golden-reddish ornamental pubescence; apices widely, conjointly arcuate.

Prosternum ( Fig. 53View FIGURES 50 – 57): Prosternal lobe large, apical margin subtruncate, without emargination or incision; prosternal process feebly expanded, disk feebly impressed, lateral corners somewhat protruding ventrad. Basal abdominal ventrite with two obvious tubercles medially; apex of last abdominal ventrite distinctly emarginate.

Aedeagus ( Fig. 72View FIGURES 58 – 76).

Length. 4.1–4.9 mm, Holotype 4.8 mm.

Sexual dimorphism. Female without apparent sexual differences, except for the absence of tubercles on the basal abdominal ventrite.

Variability. In some paratypes, the sides of pronotum are diverging arcuately, not sublinearly. The extent of white and golden-reddish elytral pubescence varies considerably among specimens ( Fig. 29View FIGURES 25 – 30).

Distribution. Malaysia: Tioman Island.

Etymology. The name of this species refers to the name of Malayan island Tioman, to which this species is probably endemic.
