Type material. Holotype: CHINA: Qinghai Prov.: 3, Mengda N. N. R. (39°49’53”M 112°35’16”E), elev. 2,200–2,500 m, Jia-Yao Hu, Liang Tang & Li-Long Zhu leg., 24.vii.2004 (SHNUC).

Description. Body (Fig. 3) darkish-brown, abdomen darker, antenna, maxillary palpi and tarsi lighter in color; body length 3.33 mm, combined width of elytra 1.51 mm.

Head longer than wide, frontal margin anterior to eyes narrowed toward apex. Antenna (Fig. 93) with scape about three times as long as wide, three times longer than pedicel, antennomeres II–III almost same in length, IV slightly longer than III, antennomeres IV–VIII subequal in length, IX–XI forming a large club, IX elongate and expanded, three times as long as VIII, X nearly quadrate, transverse, a half as long as IX, XI similar to IX, but narrowed toward apex. Maxillary palpus (Fig. 141) with palpomere I minuscule, II very long, more than twice as long as III, II–IV each protuberant on lateral sides. Mandibles (Fig. 129) each with two big teeth and several small teeth on mesal margins.

Pronotum as long as wide, coarsely punctured and densely pubescent. Elytra (Fig. 16) sparsely punctured and pubescent, apical margin angulate laterally. Legs long and robust, darkish-brown, procoxa (Fig. 58) and protrochanter each with a small apical spine, profemur with a strongly defined apical spine, protibia with a protuberance at apex, mesocoxa (Fig. 59) with an apical spine, mesofemora without spines, mesotibia with a well-defined apical protuberance, hind legs without spines.

Abdomen (Figs. 31, 32) with tergite IV twice as long as V, tergite VIII (Fig. 109) narrowed from middle toward apex, sternite VIII (Fig. 108) with apical margin strongly arcuate medially.

Aedeagus (Figs. 156, 157) with median lobe gradually narrowed from base toward apex in lateral view, weakly curved rightward in dorsal view; endophallus (Fig. 174) with basal part expanded right, apical part narrowed apicad, curved left.

Female unknown.

Remarks. This species is very unique in the coloration of the body, the aspect of antennal club, and the pro- and mesotibiae each with a basal protuberance.

Distribution. China (Qinghai Province).

Etymology. The species name is a noun in apposition (" torus " (Latin) means "protuberance") and refers to the unique basal protuberances of the pro- and mesotibiae.
