Genus Karstsinnectes Zhou, Luo, Wang, Zhou & Xiao, 2023

Karstsinnectes Zhou, Luo, Wang, Zhou & Xiao, 2023 , 696 original descriptions.

Type species.

Oreonectes anophthalmus Zheng, 1981 .

Diagnosis.

Base of anterior nostril tube-like and tip not elongated to barbel-like; anterior and posterior nostrils adjacent; lips with furrows; caudal peduncle with adipose crests; bony capsule of swim bladder opens posteriorly.

Remarks.

In the family Nemacheilidae , the genera Eonemachilus Berg, 1938 ; Karstsinnectes ; Micronemacheilus Rendahl, 1944 ; Protonemacheilus Yang & Chu, 1990 ; Traccatichthys Freyhof & Serov, 2001 ; and Yunnanilus Nichols, 1925 , are characterized by a tube-like anterior nostril with tip not elongated to barbel-like structure ( Du et al. 2021, 2023). However, Karstsinnectes can be distinguished from Eonemachilus , Protonemacheilus , Traccatichthys , and Yunnanilus by anterior and posterior nostrils adjacent (vs. separated in Eonemachilus and Yunnanilus , closely set in Protonemacheilus and Traccatichthys ) and from Micronemacheilus and Traccatichthys by lips with furrows (vs. with papillae).

Species included.

Karstsinnectes acridorsalis ( Lan, 2013) , K. anophthalmus (Zheng, 1981) , K. hyalinus (Lan, Yang & Chen, 1996) , K. longzhouensis sp. nov., and K. parvus ( Zhu & Zhu, 2014) .
