GenusKarstsinnectesZhou, 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).
