Covering an area of 58,400 hm2, the Nanling National Nature Reserve is situated at the border between Guangdong and Hunan provinces and includes the easternmost part of the Nanling range. The highest peak of the Nanling National Nature Reserve is the Shikengkong at 1,902 m (
In recent years, we conducted several collecting trips and obtained numerous

Abdomen with fine and moderately dense punctation, that of tergite VII somewhat sparser than that of anterior tergites; interstices with shallow, but distinct microsculpture; posterior margin of tergite VII without palisade fringe.
The species is named after Xing-Yang Jia, who supported us on our field trips.
The type locality is situated in the Nanling National Nature Reserve to western Ruyuan County, eastern Guangdong. The specimens were sifted from leaf litter and grass roots in shrub habitats at an altitude of 1,850 m (Fig.

Habitus as in Fig.
Head transverse; punctation coarse and dense, sparser in median dorsal portion; interstices with distinct microsculpture.
Pronotum nearly parallel-sided; punctation somewhat sparser than that of head; impunctate midline broad; interstices without microsculpture. Eyes moderately big and composed of approximately 80 ommatidia.
Elytral punctation dense and defined. Hind wings completely reduced. Protarsi without appreciable sexual dimorphism, distinctly dilated.
Abdomen with fine and dense punctation, punctation of tergite VII slightly less dense than that of anterior tergites; interstices with shallow microsculpture; posterior margin of tergite VII without palisade fringe.
The species is dedicated to Xing-Min Wang, who supported us on our field trips.
The species was found in five adjacent localities in western Ruyuan County to southern Yizhang County. Some specimens were sifted from the leaf litter of mixed deciduous forests at an altitude of 1,090 m (Fig.
