Description. Habitus elongate, fusiform. Body colouring blackish in old material, and brownish-red in recently collected specimens. Pale part of setation consists of recumbent whitish setae forming typical ocellations on pronotum, elytra and abdominal sternites, where setae are darker and sparser (Figs. 57–58).

Measurements. Males: 19–24 mm; females: 24–26 mm.

Head punctation consists of coarse setigerous punctures. Antenna robust, last antennomere 1.78–2.05 as long as wide ( Fig. 38 ), its ventral side smooth with numerous small tubercles.

Pronotum transverse, ca. 1.76–1.96 times as wide as long. Sides almost regularly rounded. Dorsal surface convex. Punctation consists of densely distributed large setigerous punctures on the disc, which become even coarser and denser laterally.

Elytra with numerous longitudinal rows of large setigerous punctures, and very fine interstitial punctures.

Ventral part almost uniformly densely punctured with fine punctures. Last abdominal ventrite slightly inflexed before apex.

Male. Aedeagus with phallobase longer than parameres. Parameres short and simple, their subbasal and subapical hook well developed. Median lobe nearly parallel sided ( Fig. 22 ).

Female. Similar to male in habitus but on average larger. Antenna shorter and more slender.

Collection circumstances. Collected at light.

Distribution. Known only from “ Tonkin ” and “ Annam ”, northern to central Vietnam.
