Tettigonia turcica Ramme, 1951 sp. rev.

( Fig. 156 )

Material examined. Turkey: Kırıkkale Province, Kılıçlar , 700 m, 4.7.1996, 1 male (leg. M. Ünal ) ( AİBÜEM); S. Anatolien , Nigde, 19 u 20.7.1937, 1 male (Holotype), 2 males (Paratypes) (leg. Ramme) ( MfN) .

Remarks. Grzywacz et al. (2017: 226), using morphology, synonymized two Anatolian species of Tettigonia , T. acutipennis Ebner, 1946 and T. turcica Ramme, 1951 , with T. armeniaca Tarbinsky, 1940 . They have no new material of these two synonymous species for molecular and acoustic studies. They gave the distribution of T. armeniaca in Turkey as eastern Anatolia, although the synonymized two species are known from Central and Southern Anatolia. They studied some specimens only from eastern Turkey. According to them, the short tegmina (less than 33 mm), the shape of the apical part of tegmina (tapering), and the less expressed black dots ventrally on the femora are different from T. caudata . Ramme (1951: 350–351) in the original description of T. turcica gave the length of male tegmina with a range of 33–41 mm, which is mainly out of the range for T. armeniaca given by Grzywacz et al. (2017).

It is necessary to study the species from the type localities of T. turcica and T. acutipennis . I have conducted field trips in Niğde Province, the type locality of T. turcica , and in MaraŞ Province, the type locality of T. acutipennis . But, all specimens found are typical T. caudata with the long tegmina with the rounded apex, the outcurved apical part of the male cercus, and distinctly blackened ventral spines of the hind femur. On the other hand, some specimens of T. armeniaca from East Anatolia (not published) have a strongly variable length of tegmina, even if in the same location as in Erzurum Province (24–40 mm) and as in Bitlis Province (45 mm). The apexes of the tegmina of those specimens are more or less tapering (not broadly rounded). The black based ventral spines of the femora are mainly quite distinct in these specimens. However, the apical tapering of tegmina is also seen in some populations of T. caudata . It seems that the length and the shape of tegmina widely overlap.

The type specimens of T. turcica were also studied by the author. Some specimens of T. caudata were recorded by Ünal (2006: 9) from Kırıkkale Province, in Central Turkey. One male has tegmina 34 mm and tapering apically, but the other specimens (1 male, 2 females) from the same location and date are typical T. caudata ( Fig. 155 ). At the same location, T. viridissima ( Fig. 154 ) was also found as a congeneric partner ( Ünal 2006b: 9). The male with short tegmina was compared with T. armeniaca from eastern Turkey and T. caudata . It is well charecterized as in T. turcica by its tegmina, longer than (typical) T. armeniaca and tapering apically; shorter than (typical) T. caudata , of which the tegmina are longer with wider and more rounded apices. Its male cercus is weakly outcurved apically, and the basal part is distinctly slender and narrower as in the holotype of T. turcica , but in T. armeniaca and T. caudata , the male cercus is distinctly more outcurved, and the basal part is stouter and wider. This single specimen is included in T. turcica and is separated from both T. caudata and T. armeniaca .

For the present, T. turcica is considered here as a valid species. Because of the above-mentioned confusion, these species should be reviewed again using the material from type localities, including the unknown female sexes of T. turcica and T. acutipennis . The female sex should not be ignored. Female subgenital plates are distinct in many species of Tettigonia and other tettigoniids.
