Redescription. Male (Xishan, ZKDC). Body length 2.6 mm. Head and pronotum largely dark brown with reddish tinge, pronotal base paler. Elytra reddish with conspicuous brown black markings on elytra ( Fig. 89 ); elytral apices reddish, posthumeral spot / band distinctly, posterior band vaguely touching lateral margins. Legs and antennae reddish.

Body moderately glossy; head and pronotum rather finely and densely punctured, elytra more coarsely punctured; punctures in basal half of elytra simple, dot-like, with smooth margins, distinctly spaced. Body setation very conspicuous, generally more raised, hirsute, mostly subdecumbent to decumbent, with numerous distinctly longer erect setae. Antebasal setose band of pronotum conspicuous, distinctly interrupted dorso-medially.

Body rather robust, less elongate. Head wide, with smaller eyes, its latero-basal outlines rounded in dorsal view. Antennae moderately long, rather robust, moderately enlarged in terminal third. Pronotum robust, globose, slightly wider than head across eyes. Pronotal horn moderately long, rather slender, slightly narrowing towards apex, armed with 4 small to distinct lateral lobules on each side and wider apical lobule ( Fig. 56 ); horn crest only moderately raised, evenly lowering towards horn apex, its lateral margins feebly marked by series of somewhat coarser, distinctly spaced lobules / rugules; dorsal surface covered with distinct rounded rugules, especially anteriorly. Elytra rather oval in shape, 1.6 times as long as wide, clearly modified, slightly bulging subapically and subtruncate apically in dorso-caudal view, with rounded gland opening near distinctly protruding lateral apical angle; humeri somewhat rounded and less distinct / protruding, hind membranous wings reduced (brachypterous); omoplates and postbasal impression absent. Legs simple. Abdominal sternum VII evenly rounded posteriorly; tergum VIII forming simple, evenly arched sclerite. Aedeagus as figured ( Fig. 36 ).

Female. Externally differing from male by simply rounded elytral apices.

Variation. Body length (J ♀) 2.4–3.0 mm. Moderately variable in colouration, such as prominence of markings on elytra.

Differential diagnosis. Notoxus sinensis can be easily separated from all Oriental species by its smaller size, robust body (wide head with smaller eyes, ovoid elytra with less prominent humeri), rather distinctive markings of the elytra, hirsute body setation, very slender pronotal horn, as well as by the male characters.

Distribution. China: Yunnan ( PIC 1907, TELNOV 2005).

Remarks. PIC (1907) described Notoxus sinensis from an unstated number of specimens deposited in his collection. The additional specimens examined fully agree with the types.
