Study on The Morphology of Lips and Associated Structures in The Cyprinid Genus Parasinilabeo

The comparative morphology of the lips and associated structures is studied among Parasinilabeo and its taxonomically related groups.On the basis of the morphological features of the lips and associated structures,Parasinilabeo is proposed to be closely associated with Pseudogyrinocheilus and Semilabeo;and four typical mouth patterns are identifled among Parasinilabeo and its taxonomically related groups.
