Comment: The original description of N. smetanai   is based on a male holotype from " China, Sichuan, Gongga Shan, above camp 2" and 15 paratypes from " China, Gansu, Xinlong Shan, ca. 70 km S Lanzhou" ( PACE 1998). The species was subsequently reported from additional localities in Shaanxi, Yunnan, Hubei by PACE (2011), who again illustrated the genitalia ( PACE 2011: figures 88-90) without indicating what specimens these illustrations are based on. Since the specimens collected by Andreas Pütz in the Hua Shan have type labels by Pace (" Holotypus [or Paratypus, respectively] Nepalota huamontis   mihi, det. R. Pace 2009 ") attached to them, the illustrations in Pace (2011) probably refer to this material.

Nepalota smetanai   is subject to remarkable intraspecific variation of external and sexual characters, which at first led me to hypothesize that the examined material was composed of two species. The material from the Qinling Shan (and adjacent mountain ranges), the Daba Shan, and the Gongga Shan is characterized by a reddish-brown to brown body, relatively short elytra (approximately 0.8 times as long as the pronotum), and a dimorphism of the hind wings, whereas the specimens from Yunnan are of darker coloration (body blackish-brown to blackish), have longer elytra (approximately as long as pronotum), and always fully developed hind wings; for illustrations the external and sexual characters of specimens from East Yunnan see Figs 29-38 View Figs 29-38 . Moreover, slight differences in the shape and size of the median lobe of the aedeagus, in the internal structures of the aedeagus, and in the secondary sexual characters were observed, while the spermatheca is practically identical ( Figs 39-64 View Figs 39-52 View Figs 53-64 ). However, in some populations in western Yunnan these characters were found to be variable: some specimens are externally identical to other material from Yunnan, but have an aedeagus of similar morphology as material from the Qinling Shan and the Daba Shan. Thus, it was not possible to unambiguously attribute them to either of the two morphs. It seems possible that these morphs represent distinct subspecies, but additional (e.g., molecular) evidence would be needed to clarify their status. Therefore, for the time being, the observed differences are interpreted as intra- rather than inter(sub-)specific variation.

Distribution and natural history: Nepalota smetanai   is one of the most common representatives of the genus in China, its distribution ranging from Hubei and Shaanxi in the north and northeast to Yunnan in the south ( Map 5 View Map 5 ). The examined material was sifted from litter in various types of forest and shrub habitats at altitudes between 1200 and 3000 m. On numerous occasions it was found together with other species of the genus, mostly N. gansuensis   , but also N. franzi   , N. martensi   , and N. cuneata   .
