Bufotes pewzowi

Bufotes pewzowi is a species of toad in the family Bufonidae. It is found in dry plains of Central Asia, the foothills and mountains of Tian Shan, Zhungar Alatau and Pamir Mountains (Kazakhstan, Kyrgyzstan, Uzbekistan, and Tajikistan), the mountains and deserts of Western China and Mongolia, and probably westward to northern Afghanistan and north to Lake Balkhash in Kazakhstan and northeast Altai Republic in Russia. The specific name pewzowi honours Michail Wassiljewitsch Pewzow , a Russian geographer, cartographer, and explorer. Common names include Xinjiang toad and Pewzow's toad; when subspecies B. p. strauchi is recognized, it can be referred to as northern Xinjiang toad, while the nominotypic B. p. pewzowi then becomes southern Xinjiang toad.

Appearance

Bufotes pewzowi is a tetraploid species that originates from hybridization between Bufotes latastii and Bufotes perrini. Adult males measure 52–77 mm (2.0–3.0 in) and adult females 50–86 mm (2.0–3.4 in) in snout–vent length. Gosner stage 35–37 tadpoles measure about 45 mm (1.8 in) in total length, of which the tail makes almost two thirds.
