Diagnosis. Larger, elongate species; body reddish brown, elytra in apical two thirds black and with two narrow, transverse, pale reddish bands ( Fig. 78 , the anterior band only vaguely indicated between reddish base and black rest of elytra); head with conspicuously large eyes; tempora nearly evenly narrowing posteriad; pronotal horn moderately long and wide, with wider apical and several smaller lateral lobules; horn crest distinctly raised, evenly lowering towards horn apex, its lateral margins feebly marked by series of somewhat coarser, distinctly spaced lobules / rugules; elytra more than twice as long as wide; punctation in basal half of elytra rather fine but distinct.

Male characters (Renok, NHMB). Elytral apices nearly simple, at most moderately angled apically near slight gland opening; protibiae modified, slightly sinuous and moderately angulately produced on inner side close behind mid-length; abdominal sternum VII slightly flattened postero-medially, nearly simple, its posterior margin somewhat widely rounded in ventral view; tergum VIII forming narrow, arched sclerite, evenly rounded and finely setose posteriorly; aedeagus as figured ( Figs. 4, 5 ).

Variation. Body length (J ♀) 3.6–4.3 mm. Moderately variable in shape (width) of pronotal horn; its lateral margins with 3–6 lobules on each side, apical lobule simply, widely rounded to moderately emarginate.

Distribution. India: Assam, Arunachal Pradesh, Uttarakhand, West Bengal (Darjeeling Distr.); Nepal (KREKICH- STRASSOLDO 1913, TELNOV 2003, CHANDLER et al. 2008).

Remarks. KREKICH- STRASSOLDO (1913) described Notoxus assamensis from two specimens deposited in the NHMW and BMNH. It is reliably known only from northern India and Nepal. The record from Vietnam by TELNOV (2005) is based on single female specimen, bearing data ‘Annam-Vinh 1910 // Indo Chine Coll. Dussault’, and re-identified here as N. donckieri (see below).
