Review and key to species of Platycleis from Turkey (Orthoptera: Tettigoniidae) with descriptions of Yalvaciana subgen. n. and two new species.

Species of Platycleis from Turkey are reviewed. Twenty-three species are recorded: Platycleis affinis (Fieber, 1853), P. albopunctata (Goeze, 1778), P. escalerai (Bolívar, 1899), P. intermedia (Serville, 1838), P. incerta Brunner von Wattenwyl, 1882, P. persica Uvarov, 1917, P. ankarensis (Karabag, 1950), P. armeniaca Ramme, 1951, P. elegans (Uvarov, 1934), P. schereri Werner, 1901, P. taurica Bolívar, 1899, P. uvarovi Karabag, 1950, P. sepium (Yersin, 1854), P. sporadarum (Werner, 1933), P. kurmana (Ramme, 1951), P. melendisensis sp. n., P. sinuata Ramme, 1951, P. salmani sp. n., P. weidneri (Demirsoy, 1974), P. nigrosignata (Costa, 1863), P. tessellata holoptera Ramme, 1951, P. veyseli Koçak, 1984, P. yalvaci (Demirsoy, 1974). Keys to subgenera and species, necessary figures and distribution maps are provided. A new subgenus Yalvaciana subgen. n. is established to include Decorana yalvaci Demirsoy. Two new species, P. salmani sp. n. and P. melendisensis sp. n. are described. Montana bifoveolata Karabag syn. n. is placed in synonymy with Platycleis schereri Werner. Metrioptera brevipes Uvarov is placed in synonymy with P. sporadarum Werner in subgenus Sporadiana Zeuner. Platycleis (Squamiana) sinuata Ramme, 1951 is transferred from subgenus Platycleis. Song oscillograms from P. armeniaca and P. taurica are presented. Platycleis (Montana) armeniaca Ramme is a new record for Turkey. [ABSTRACT FROM AUTHOR]
