Cobitis evreni  Erk'akan, Özeren & Nalbant, 2008

( Fig. 10View FIGURE 10)

Cobitis evreni  Erk'akan, Özeren & Nalbant, 2008a: 112, fig. 1 (type locality: Turkey: Kömür stream, Göksun, Kahramanmaraş, 38.014 36.508).

Material examined. HUIC uncat., 1, 78 mm SL; Turkey: Kahramanmaraş prov.: stream Kömür , 38.014 36.508.— FFR05530View Materials, 1, 75 mm SL  ; Turkey: Kahramanmaraş prov.: stream Terbüzek about 2 km south of Göksun , 38.001 36.598  .

Material used in molecular genetic analysis. HUIC 299View Materials TK-300TK; Turkey: Kahramanmaraş prov.: stream Göksun east of Göksun, at road to Yantepe , 38.024 36.515. (GenBank accession numbers: KJ 552911, KJ 553207)  .

Diagnosis. Cobitis evreni  is distinguished from C. battalgilae  and C. bilseli  by the pigmentation in Z4 being fused into a dark-brown stripe reaching from above the pectoral-fin base until the anus or beyond (vs. blotches in Z4 usually vertically elongate or squarish, often dissociated into a band of small irregularly-shaped blotches and spots), lacking the pelvic axillary lobe (vs. often present, absent in some individuals), lacking the black spot at the uppermost caudal-fin base (vs. present) and having two laminae circularis in the male (vs. one in C. bilseli  ). It is distinguished from C. elazigensis  by Z4 formed by a dark-brown stripe reaching from above the pectoral-fin base until the anus or beyond (vs. Z4 organised by blotches), lacking the pelvic axillary lobe (vs. present) and lacking the black spot at the uppermost caudal-fin base and lacking the axillary pelvic lobe (vs. present).

Distribution. Cobitis evreni  seems to have a very restricted range in the middle Ceyhan River drainage where it is found in the streams Göksun, Savrun and Hamus.

Remarks. Molecular data ( Fig. 1View FIGURE 1) place Cobitis evreni  not into one of the species groups mentioned before. Molecular data presented by Perdices et al. (2018) place C. evreni  into the C. linea  species group, at a very basal position. See below for details to distinguish C. evreni  from other species in the C. linea  species group and from other Cobitis  species found in the Asian Mediterranean Sea basin. Cobitis evreni  has not been found in the lower Ceyhan, which is inhabited by C. aliyeae  described below. Based on DNA barcoding Cobitis evreni  is well separated from all other included Cobitis  and by a minimum K2P distance of 7.0% to C. elazigensis  , also supported as PTP and mPTP entity.
