Chobanov, Dragan P., Kaya, Sarp & Çiplak, Battal, 2015, Contribution to the taxonomy of Poecilimon bosphoricus species group (Orthoptera: Phaneropteridae): two new species from its core range, Zootaxa 3964 (1), pp. 63-76 : 74

Key to the species affiliated to the Subgroup 2 of the P. bosphoricus group

1a Male cercal apex narrower than the base of cerci, pointed apically ( Figs 3–5 C). Female lamellae less expanded ventrally, forming either a very narrow and deep or less widened pit ( Fig. 10–12 A). Stridulatory teeth number 86–117 (usually over 90). Song ( Fig. 17, 18 , 21, 22 A, B, 24–27) with a higher number of impulses (mean>14) in the second part...................... 2

1b Male cercal apex very wide, wider than the base of cerci, shovel-shaped ( Fig. 2 C). Female lamellae ventrally expanded and widely rounded, forming large shallow pit ( Fig. 9 A). Stridulatory teeth number 70–90. Song ( Fig. 16 A, B) with a low number of impulses (mean 11±2) in the second part.......................................................... P. turciae

2a Male cercal apex with teeth on both the external and internal/dorso-internal apex, not distinctly narrow, ending with a short tooth ( Fig. 4, 5 C, D). Female lamellae longer, forming bigger shallow pit ( Fig. 11, 12 A, B)........................... 3

2b Male cercal apex with a few teeth only on its external margin, narrowly pointed, ending with a long strong tooth ( Fig. 3 C, D). Female lamellae short and laterally expanded, forming small deep pit ( Fig. 10 A, B)......................... P. turcicus

3a Male cerci almost straight along their basal 3/4, the tip angularly incurved ( Fig. 5 C); cercal apex not wider than the preceding part, not lanced-shaped, outer row of teeth longer than the inner one, outer row with 3–7, inner with 2–4 teeth ( Fig. 5 D). Female lamellae shorter, with a distinct incision dividing them into a small anterior and large posterior lobe, forming narrower pit ( Fig. 12 A, B)..................................................................................... 4

3b Male cerci evenly incurved along to the tip ( Fig. 4 C); cercal apex wider than the preceding part, lanced-shaped, length of the outer and inner rows of teeth almost equal, outer row with 6–13, inner with 4–8 teeth ( Fig. 4 D). Female lamellae longer, not distinctly incised, forming wider pit ( Fig. 11 A, B)......................................... P. warchalowskae sp. n.

4a Apical fourth of male cerci narrower than the preceding part ( Fig. 5 C, D); male subgenital plate strongly constricted in apical third ( Fig. 5 E). Distributed in Biga Peninsula in NW Anatolia, Turkey ( Fig. 28 )..................... P. c a n a k k a l e sp. n.

4b Apical fourth of male cerci equal or slightly wider than the preceding part (see Fig. 4 in Tilmans et al. 1989), male subgenital plate weakly convergent apically ( Fig. 7 E). Distributed in the Athos Peninsula of the Balkans, N Greece ( Fig. 28 ).... P. athos
