Distribution. China: Gansu, Qinghai, Ningxia, Shaanxi, Sichuan, Chongqing, Hubei, Anhui (new province record).

Comments. The species is easily distinguished from other members of the genus by the central pronotal protuberance with the anterior half at most shallowly depressed at middle and not forming a deep gap (Figs 28, 31, 34, 37), and the elytral surface from the basal fifth to the top of the apical declivity remarkably flat and sometimes slightly depressed dorsally, nearly vertical dorsal-laterally.

The body size, shape of the central pronotal protuberance and lateral pronotal spine, and the size of tubercles on elytra of the species are variable. One male individual from Ningxia has the body length only 14mm, the central protuberance on the pronotal disc is short with the dorsal surface flat, and the elytral tubercles small ( Figs 5 , 18 , 39–41). One male individual from Anhui has the same body size with the former but the central pronotal protuberance is strongly elevated with the anterior margin broadly and shallowly depressed ( Figs 6 , 43). However, individuals from Hubei always have the well-developed central protuberance on the pronotal disc and dentate tubercles on the elytral carinae, and the apical portion of the lateral pronotal spine more elongated. Individuals captured in Daolaoling Nature Reserve at the same time and locality present a different appearance: some with large size ( Fig. 2 , 26 mm), some with small size ( Fig. 4 , only 16 mm), some with the central pronotal protuberance rounded laterally (Figs 28, 31), some with the central pronotal protuberance distinctly narrowed posteriorly (Figs 34, 37, 40, 43), and some with the central pronotal protuberance with several more distinct depressions on the dorsum (Figs 28, 31).
