Karstsinnectes acridorsalis

(Lan in Lan, Gan, Wu and Yang 2013) Luo et al 2023

CypriniformesCobitoidei Nemacheilidae


Oreonectes acridorsalis  Lan in Lan, Gan, Wu and Yang 2013


Holotype: CLJH 04100608 48.3mm SL. Paratypes: CLJH 04100607, 94100609, 04100610, 12020001 37.5mm - 48.0mm SL


Known from the type locality only: A cave in Brama town (The Hongshui River), Tian'e County, 24.9°N, 107.2°E, Guangxi, China, elevation 286 meters.


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.
