Triplophysa (Rendahl)


[[ Triplophysa (Rendahl)  ]]

In our collection, five species ( T. yarkandensis yarkandensis  , T. papilloso-labiatus  , T. stewarti  , T. orientalis  and T. laterimaculata  n. sp. all live in the Kezile River system; T. stewarti  and T. orientalis  are rare. The last four species possess two types of free posterior portion of air bladder, and two types of caudal peduncle. The degree of development of the posterior chamber is an adaptative character, and the different forms of the air bladder have general phylogenetic significance (Hora 1937; Zhu 1986; Bǎnǎrescu & Nalbant 1995). The shape of the caudal peduncle is related to the strength of the current (Hora 1922). Different types of air bladder and caudal peduncle are related to different types of habitats. T. laterimaculata  and T. papilloso-labiatus  are probably closest relatives.
