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 , 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. Description. "Bufotes pewzowi" is a tetraploid species that originates from hybridization between "Bufotes latastii" and "Bufotes perrini". Adult males measure and adult females in snout–vent length. Gosner stage 35–37 tadpoles measure about in total length, of which the tail makes almost two thirds. Habitat and conservation. "Bufotes pewzowi" occurs in dry steppes, grasslands, semi-deserts and deserts, and in mountains from foothills through all altitudinal belts up to subalpine meadows, perhaps to over above sea level. The tadpoles develop in oases, ponds, and pools. It  is a very common species that can be found in very disturbed habitat. No major threats to this species are known. It can suffer from extreme habitat modification and from collection for traditional medicine. It probably occurs in several protected areas within its range.
