Systematics
Oreonectes barbatus was transfered to the hypogean-restricted genus Troglonectes by Zhang and Zhao (2016). Lan et al. (2013) suggest that T. barbatus is very similar to T. acrodorsalis. They also suggest that it is close to Triplophysa longibarbata but this is clearly not a view shared by Zhang and Zhao (2016).
There are 19 described species in the genus Troglonectes (Eschmeyer 2022), all expect one are hypogean fishes with reduced eyes, reduced pigment and reduced scales. The only epigean member of the genus is Troglonectes hechiensis Zhao, Liu, Du and Luo 2021. The epigean species is a member of a monophyletic group which also contains T. furcocaudalis, T. daqikongensis, T. jiarongensis and T. shuilongensis (Zhao, Liu, Du and Luo 2021).
