Distribution.

China (Guizhou). Known from three limestone caves in Guiyang Shi and Longli County, Qiannan Buyi & Miao Autonomous Prefecture (Fig. 1 ).

This species was described from Shuijing Dong cave, Longli County, Qiannan Buyi & Miao Autonomous Prefecture ( Ma et al. 2020). Then it was found in Jianlong Dong, Guiyang and Duocai Dong, Longli.

Jianlong Dong cave (Fig. 14 ) is located at the eastern suburb of Guiyang, about 40 km from Shuijing Dong, the type locality of S. chengguangyuani . This cave is a municipal protected area because of the engraved inscriptions on the precipices inside dating from the Ming Dynasty, over 400 years ago (Fig. 14A ). The rather large entrance is just on the side of the road Jianlonglu (Fig. 14B ). The cave is about 100 m long, with two chambers inside. The first half part is rather dry, then becomes wet in the inner part (Fig. 14C ). All of the beetle individuals were collected in the inner part, running on the ground or on the wall. Other cave animals observed in this cave were millipedes ( Glyphiulus sp., Fig. 14E ), a snake ( Elaphe mandarina Cantor, 1842; Fig. 14F ), crickets and moths.

Duocai Dong is a stalagtite-rich cave, about 5 km from Shuijing Dong in straight line. The two individuals were collected in dark zone, running on the wall (Fig. 15 ).
