Holotype: CNGZNU20110128001 77.14mm TL and 61.46 mm SL. Paratypes: CNGZNU20110128002–CNGZNU20110128026 (25). Zoobank registered.


Known only from the type locailty: A subterranean river of the Daqikong area, Libo County, Guizhou, China.(N 25°17'05.1", E 107°44'54.3". Altitude 488 m).


This species was found only in the Daqikong scenic area. The opening of the cave was halfway up the mountain, and the distance from the opening to the pool was about 15–20 m. The cave got no sunshine because of the twisty pathway. A large number of Hipposideros armiger lived in the cave and a thick layer of bat dung was found on the ground. Groundwater extended into the cave, and the water rushed outside the cave in the case of heavy rain. So far, no other fish, shrimps, or aquatic animals were found in the cave. The subterranean river belonged to the Dagou river system, and was the main river of the Libo County, which runs through the whole county, enters Guangxi from the Laocun Xiang, and was the major tributary of the Duliu River system.


The sister species of O. daqikongensis is O. shuilongensis and this pair is sister to O. platycephalus (Deng et al. 2016).

Biological Notes

The whole body of the living species is pale pink and translucent, where the vertebra, body segment at caudal peduncle, cardinal gill, and internal organs are visible. Its body color is unlikely to change when it is fed in the laboratory under light
