Zoogeographic Regionalization of Southwestern Tajikistan Based on the Orthoptera Distribution

摘要

A new scheme of zoogeographic regionalization of Southwestern Tajikistan based on the data on the Orthoptera distribution is proposed. The main foci of species endemism are distinguished. The species diversity is higher in the plain (up to 800 m abovesee level) zoogeographic entities than in the mountain entities of comparable size. The distribution of Orthoptera m Tajikistan is un evenly studied. There is more or less detailed informa tion on Southwestern (SW) Tajikistan (Miram, 1935 1949; Antova,1949; Mishchenko, 1949; Chernya khovskii, 1985; Sergeev, 1987; Pokivailov, 2000 2003, etc.). The Hissar Range (Mishchenko, 1951; Se redina, 1973, 1977; Fedotova, 1980) and the Cis-Pami and Pamir mountains (Bey-Bienko and Mishchenko 1951; Mishchenko, 1952a; Stolyarov, 1973; Sergeev 1986, 1988a, 1988b, 1993, 1995) are studied in les: detail, whereas data on the faunas of the Zeravshai and Turkestan ranges (Davletshina, 1949; Pravdin 1962) and Northern Tajikistan are very scarce.
