Poecilimon rufonitens Ingrisch et Pavićević 1985: 51 –54, by synonymy with P. anatolicus Ramme.

Note on the synonymy: P. anatolicus has been synonymised with P. sureyanus by Kaya et al. (2012). Ünal (2012) re-established P. anatolicus on account of differences in the orientation of the cercal teeth and some characters considered by Ramme (1951). According to Ramme (1951) both taxa differ in the number and size of cercal teeth and the length and shape of male subgenital plate. However, when observing rich material (see Kaya et al. 2012), the mentioned differences become less obvious with more or less smooth transition of characters between populations. The number of cercal teeth largely varies within populations of P. anatolicus / sureyanus , which is observed in other taxa of the group as well (compare Table 1 in Kaya et al. 2012 and Table 1 in this paper). This may be observed when compare the cerci of a syntype specimen of P. anatolicus presented in OSF online ( Eades et al. 2015 on Fig. 14 here; see http:// orthoptera .speciesfile.org/Common/basic/PopImage.aspx?ImageID=148759&width =640&Full=1) with the cerci of the holotype specimens of P. sureyanus from the same source ( Eades et al. 2015 http:// orthoptera .speciesfile.org/Common/basic/PopImage.aspx?ImageID=148759&width=640&Full=1; Fig. 15 ). Significant variation may be observed between the left (with at least 7–8 external teeth) and right (with about 5 external teeth including the apical tooth) cercus of the syntype of P. anatolicus ( Fig. 14 ). Thus, the left cercus of the latter specimen is similar to the cerci of the holotype of P. sureyanus ( Fig. 15 ). Regarding the position of teeth, in both specimens and all studied material the internal teeth row has a dorso-apical position, while the external one is proximally positioned. The male subgenital plate ( Fig. 1 E) is generally longer in the European populations, while being significantly variable in the Anatolian specimens (see Figs 94 and 109 in Kaya et al. 2012); in addition to variation its hind margin may look truncated, convex or concave depending on the angle of observation (compare Fig. 1 C and 1E). In addition, concerning the acoustic similarities all over the range of P. anatolicus and P. sureyanus , the similar colouration and morphology (incl. number of stridulatory teeth) (see Kaya et al. 2012: Figs 175, 176 and Tables 1 –3) we consider both taxa synonyms of one variable species, for which the name P. sureyanus should be used for having priority. Additionally, the range pattern of this taxon (incl. P. anatolicus and P. sureyanus ) in relation to other species in P. bosphoricus group indicates for a geographically discrete population ( Kaya et al. 2012; own unpublished data).

The synonymization of P. diversus Ünal, 2010 with P. sureyanus by Kaya et al. (2012) has been rejected by Ünal (2012). Indeed, the cercal shape of P. diversus is characteristic for the southernmost populations of the Subgroup 1, found in the mountainous belt from the border of Balıkesir and Kütahya provinces in the West to the Kazdağı Mts (formerly reported as P. anatolicus by Sevgili et al. 2011 and as P. sureyanus by Kaya et al. 2012: see Fig. 82G) in the East, between 31.5° and 40° latitude. The song of these populations entirely corresponds to the song pattern of P. sureyanus but we refrain to discuss its taxonomic status until genetic data will be available.
