Systematics
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).
Luo et al. (2023) propose that this species (together with three others: the hypogean species Troglonectes acridorsalis, Oreonectes anophthalmus, Heminoemacheilus hyalinus and the epigean Heminoemacheilus parva be relocated in to the new genus Karstsinnectes. However, there is some uncertainty that this generic name was properly defined and further information is required.
The genus Karstsinnectes currently has seven species (K.acridorsalis, K. cehengensis, K. parvus, K. longzhouensis, K. anophthalmus, K. hyalinus and K. daxinensis). These are in two major clades, one containing K. acridorsalis and K. cehengensis, and the second containing K. parvus, K. longzhouensis, K. anophthalmus and K. daxinensis. The position of the seventh species, K. hyalinus, has not been ascertained.
Karstsinnectes acridorsalis is sister species to K. cehengensis.
