(GenBank accession numbers:  KP 050530,  KP 050539).   Diagnosis.  Cobitis lineais distinguished from  C. avicennaeand  C. kellei, two other species from the Persian Gulf basin, by having two laminae circularis in the male (vs. one). It is distinguished from  C. elazigensis, the only other  Cobitisspecies in the Persian Gulf basin having two laminae circularis, by the lack of an axillary pelvic lobe (vs. present) and the blotches in Z4 very small and roundish or comma-shaped along its whole length, densely set, often fused to short stripes or dissociated into an open field of several rows of small spots and blotches (vs. blotches in Z4 irregularly squarish, between vertical of pectoral-fin origin and dorsal-fin base, roundish and usually widely spaced posterior to the dorsal-fin base, not fused into stripes).   Cobitis lineais distinguished from  C. evreniand C. levantinaby the blotches in Z4 very small and roundish or comma-shaped along the flank, densely set, often fused to short stripes or dissociated into a field of several rows of blotches (vs. blotches horizontally elongate or squarish anterior to the dorsal-fin origin, fused into a stripe in some  C. levantina, Z4 is formed by a dark-brown stripe reaching from above the pectoral-fin base until the anus or beyond in  C. evreni).  Cobitis lineais further distinguished from C. evreniby the presence of the black spot at the uppermost caudal-fin base (vs. absent) and from C. levantinaby the maxillary barbel reaching the vertical of the front margin or the middle of the eye (vs. not reaching).   Distribution.  Cobitis lineais endemic to the Kor River drainage, an endorheic basin in Central Iran.   Remarks.Molecular data ( Fig. 1) place  Cobitis lineain a species group with  C. aliyeae,  C. anabelae,  C. elazigensis,  C. erkakanae, and  C. levantina. Based on DNA barcoding it is well separated from all other included  Cobitisand by a minimum K2P distance of 4.7% to  C. elazigensis, also supported as PTP entity. See below for details to distinguish  C. lineafrom other species in the  C. lineaspecies group. 2120485284 FSJF Iran Dashtak River Kor 24 25 FSJF 2240, 15, 38-100 1 Fars 2120487216 FSJF Iran Shiraz prov.
