Abstract: | Comprehensive comparative morphological analysis of loaches from the subfamily Nemacheilinae is conducted. Forty significant
phylogenetic characters are suggested, and phylogenetic relationships are reconstructed. The subfamily Nemacheilinae is subdivided
into five tribes (Vaillantellini, Lefuini nov., Yunnanilini nov., Triplophysini nov., and Nemacheilini), and the relationships
between these tribes can be expressed by the following formula: Vaillantellini (Lefuini (Yunnanilini (Triplophysini + Nemacheilini))).
The classification of highland Asian loaches (Triplophysini) is specified, and the revised diagnoses of the genera from this
tribe are given. Heterogeneity of the genus Triplophysa is demonstrated. This genus can be divided into several subgenera, and three new subgenera (Labiatophysa subgen. nov., Indotriplophysa subgen. nov., and Tarimichthys subgen. nov.) are described. A new species Hedinichthys grummorum sp. n is described from the Turpan Depression (northwest China). |
