Poecilimon turciae (Ramme) ; Bei-Bienko 1954: 327 –328.

Examined material. 16 ♂♂, 14 ♀♀, Turkey (NW Anatolia), Bursa prov., 4 km N of Boyalıca, Kızderbent, 40.514° N, 29.5517° E, 280 m alt., 25.06.2012, S. Kaya & B. Çıplak leg., AUZM.

Note: Kaya et al. (2012) use a male of Poecilimon from the region of Gelibolu [Umg. Gelibolu (40° 24' N, 26° 40' E), 0 9.5.1985 (leg. E. Blumm)] to supplement the description of P. t u rci ae with morphological and song data, which herewith is considered as belonging to an undescribed species—see below. Part of the illustrative material correspond to the type specimens of P. turciae by Willy Ramme ( Kaya et al. 2012: Figs 9 , 26 , 40, 68, 125), but the rest of the data ( Kaya et al. 2012: Figs 161, 175–185, P. t u rc i ae in Tables 1 –3) should be referred to the below described new species, P. warchalowskae sp. n..

Supplement to the description and a diagnosis. Morphology ( Figs 2 , 9 ) typical for the P. bosphoricus species group with the body shape, size and colouration resembling mostly Subgroup 1 members, especially P. sureyanus , characteristic with strongly developed melanism and a tendency of merging the lateral red spots of the metazona. P. turciae is similar to P. kocaki Ünal, 1999 (compare with Ünal, 1999 and Kaya et al. 2012) in the shape of male pronotum and subgenital plate. The stridulatory row has low number of teeth (70–90), which might also indicate to the relationships with the taxa of Subgroup 1 and 2. Male cerci ( Fig. 2 C, D, 16C) are similar in shape to those of P. heinrichi ( Ramme, 1951) but the difference in the song pattern (compare data below and Kaya et al. 2012), the great difference in the number of stridulatory teeth (192–208 in P. he i n r i ch i) and other morphological characters suggest the convergent similarity of cerci in these two species. Female lamella has similar shape to that of P. sureyanus (compare Figs 8 A, B with 9A, B) and concerning the other similarities distinction based on females is problematic.

Measurements. See Table 1 .

Bioacoustics ( Table 2 ). Though P. t u rci a e has morphological affinities with species in Subgroup 1 of the P. bosphoricus group (see Kaya et al. 2012), its calling song shows characteristics of type 2 by having a distinguishable second part. Male song ( Fig. 16 A, B) consists of single or sparsely grouped syllables repeating over period of a few seconds. The syllables are long—at 24–25°C they lasted 170–360 ms. Impulses in a syllable are arranged into two parts on account of the mean impulse period—a first (early) part of 6–12 (usually 8–10) sparse impulses (impulse period of 20–90 ms) and a second (late) part of 6–14 (usually 10–11) dense syllables (impulse period of 3–9 ms). Main song frequencies lie between 20 and 30 kHz with peaks between 20–25 kHz.

Distribution ( Fig. 28 ) and ecology. P. turciae occurs along the eastern coast of the Sea of Marmara (NW Asian Turkey). The species inhabits mesophytic shrub associations and has been found to co-occur with P. miramae Ramme, 1933 . According to Ünal (2010) it has also been found together with P. similis proximus and P. naskrecki Ünal, 2001 .
