Note

This species was first mentioned in Yu et al. (2021). But current thinking suggests that this account does not conform to the rules of the International Code of Zoological Nomenclature (ICZN 1999). If this is confirmed the name is not validly published and it will require a decision of the International Commission of Zoological Nomenclature as to the future useage, or not, of this name.

Biological Notes

This species is provisionally accepted as a stygobite based on the following:

"With the deepening of cave life, the eye diameter of the S. xiaotunensis is smaller than the S. zhenfengensis, which is related to the light intensity of the living environment (Langecker et al. 1995; Zhou et al. 2009). Not only that the dorsal and pectoral fins of S. xiaotunensis became shorter and the number of fin spines increased. This is an adaptive change to the living environment, and its balance function has been further adapted to evolve and it showed obvious difference from S. zhenfengensis in morphology." (from Yu et al. 2021).
