Clarification of Phylogenetic Relationships among Chinese Nemacheilids with Tube-Shaped Anterior Nostrils, with a Description of a New Genus and Two New Species

چکیده
Nostril structures are important characteristics for generic diagnosis in Nemacheilidae and Cobitidae. Based on phylogenetic analysis, we found that 10 genera within (Eonemachilus, Guinemachilus, Lefua, Micronemacheilus, Oreonectes, Paranemachilus, Protonemacheilus, Traccatichthys, Troglonectes, Yunnanilus) shared tube-shaped anterior nostrils formed a monophyletic group. Morphologically, the location between posterior was divided into three types: (i) separated, i.e., distance greater than 1.5 times diameter of nostril; (ii) adjacent, shorter (iii) closely set, margin nostril connected to nostril. Thus, can be distinguished based features. Additionally, describe one new genus, Guinemachilus gen. nov., two species, pseudopulcherrimus sp. nov. Paranemachilus chongzuo
