Cobitis linea (Heckel, 1848) 

( Fig. 18View FIGURE 18)

Acanthopsis linea Heckel, 1848: 267  (type locality: Iran: creeks around Persepolis [Marvdasht Plain, about 70 km northeast of Shiraz]).

Material examined. FSJF 2240, 15, 38–100 mm SL; Iran: Fars prov.: River Kor about 10 km south of Dashtak , 30.193 52.465  .— FSJF 3219, 8, 32–39 mm SL; Iran: Shiraz prov.: Malous spring 10 km north of Shiraz , 29.877 52.481  .

Material used in molecular genetic analysis. FSJF DNA-1982, Iran: Shiraz prov. : Malous spring 10 km north of Shiraz, 29.877 52.482. (GenBank accession numbers: KP 050530, KP 050539)  .

Diagnosis. Cobitis linea  is distinguished from C. avicennae  and 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 Cobitis  species 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 linea  is distinguished from C. evreni  and C. levantina  by 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 linea  is further distinguished from C. evreni  by the presence of the black spot at the uppermost caudal-fin base (vs. absent) and from C. levantina  by the maxillary barbel reaching the vertical of the front margin or the middle of the eye (vs. not reaching).

Distribution. Cobitis linea  is endemic to the Kor River drainage, an endorheic basin in Central Iran.

Remarks. Molecular data ( Fig. 1View FIGURE 1) place Cobitis linea  in 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 Cobitis  and by a minimum K2P distance of 4.7% to C. elazigensis  , also supported as PTP entity.

See below for details to distinguish C. linea  from other species in the C. linea  species group.
