Description. Habitus elongate, fusiform. Body colouring from brownish-red to brown. Pale part of setation consists of recumbent yellowish or greyish setae covering uniformly body surface, or forming very indistinct ocellations on elytra (Fig. 17).
Measurements. Males: 16–19 mm; females: 20–22 mm.
Head punctation consists of sparse moderately large setigerous punctures. Antenna slender, last antennomere filiform, 3.75–4.25 times as long as wide (Fig. 38), its ventral side smooth.
Pronotum trapezoidal, ca. 1.81–2.03 times as wide as long. Sides almost straight, in some specimens with indistinct obtuse angle behind the middle (Fig. 58). Pronotum with two oval shallow depressions on the disc, and indistinct depressions medially also along anterior and posterior margin. Punctation consists of sparse moderately coarse setigerous punctures on the disc, which become slightly coarser and denser laterally.
Elytra with numerous longitudinal rows of moderately large punctures, and very fine interstitial setigerous punctures.
Ventral part with fine punctures, which are sparse medially and become larger and denser laterally. Last abdominal ventrite laterally with indistinct sinuation before apex.
Male. Aedeagus with phallobase of the same length as parameres. Parameres simple, broad, their subbasal hook is missing, but the subapical hook is developed and obtuse. Median lobe narrowly lanceolate (Fig. 78).
Female. Similar to male in habitus, but larger. Antenna shorter, and more slender.
Distribution. The species is known from upland areas of Nepal and northern India (Uttaranchal, Sikkim, West Bengal). The occurrence in Bhutan needs to be verified by precisely localised specimens.
