Poecilimon (Poecilimon) inflatus Species Group stat. rev.

The species group can be defined by the combination of two characters. The first is inflated metazona especially in males. In lateral view dorsal margin of pronotum is almost straight in prozona, starting raising after the mid sulcus up to 2/3 of metazona and later curve downward constituting a blister-like inflation ( Figures 3 , 4 , 7 , 8 ). The caudal margin of metazona is convex or produced backward. Due to elevation of the metazona the caudal margin of the paranota is oblique or slightly S-shaped constituting distinct shoulders. In parallel with extending of pronotum, male tegmina are fully or almost fully concealed by pronotum. The above described characters are typical for four species; P. inflatus , P. martinae , P. cretensis and Pa. antalyaensis . The inflation of pronotum is indistinct, caudal margin of metazona is almost truncate or indistinctly convex and tegmina are slightly visible in P. bilgeri and P. isopterus sp. n. However, the caudal margin of metazona is more or less down curved and shoulders are distinguishable in these two species as in other members of the group. The second character, unique to the group but not shared by all species, is the male cerci black in their apical one-third to half in most of the species (black only along denticles in P. bilgeri , P. antalyaensis antalyaensis and P. cretensis ). Further, the male cerci are slightly curved and mostly with a few small denticles ( Figure 9 ). Although P. bilgeri and P. isopterus sp. n. seem to be aberrant to others DNA data (Çıplak et al.; unpublished data) support monophyly of the group. Thus, both inflated metazona and male cerci black in apical half are the characters defining the P. inflatus group. Besides these two characters the fastigium less than one-third of scapus and the first tergum without a tubercle are further characters to distinguish the group from other members of Poecilimon .

P. inflatus and P. cretensis are the members of the group based on indication by Ramme (1933). P. martinae is another member of the group as Heller (2004) suggested it sister species to P. inflatus . Heller (2004) proposed P. bilgeri Karabağ, 1953 as another possible member of the group. Karabağ (1975) defined the monotypic genus Parapoecilimon as intermediate between Isophya and Poecilimon . However, Parapoecilimon antalyaensis share typical synapomorphies with the members of P. inflatus group (see Heller 2004). Further, there is no other character to diagnose Parapoecilimon from Poecilimon . Phylogenetic trees based on mitochondrial and nuclear DNA sequences ( Ullrich et al. 2010) also suggest Parapoecilimon as an internal branch within Poecilimon . In the light of these data we synonymise genus Parapoecilimon Karabağ 1975 syn. n. with Poecilimon Fischer, 1853 and use a new combination for Parapoecilimon antalyaensis Karabağ (1975) — Poecilimon antalyaensis ( Karabağ, 1975) comb. n.

Examination of new material belonging to Poecilimon antalyaensis revealed three forms diverging in morphology and song. With this decision we are defining two new subspecies in the species. A similar case is also observed for P. inflatus . The population of this species ranging from Kemer to Demre exhibits morphological differences from the remaining part and this distinctness is well supported by genetic data (Çıplak et al.; unpublished data). Thus, we split this species into two subspecies. Under the above given statements the Poecilimon (P.) inflatus species group consists of the following species and subspecies.
