( Fig. 22View FIGURE 22)

Cobitis taenia satunini Gladkov, 1935: 73  (type locality: Georgia: Kintrich River [entering Black Sea at 41.803, 41.769]).

Material examined. FSJF 3559, 5, 35–78 mm SL; Georgia: Rioni River delta, southern branch, 42.180 41.646  .— FSJF 3583, 1, 81 mm SL; Georgia: Urduni River at Ul'yanka , 41.948 41.937  .— FSJF 3597, 1, 85 mm SL; Georgia: Chakhota River at Natanebi , 42.933 41.836  .— FSJF 2372, 3, 68–93 mm SL; Turkey: Artvin prov.: stream Hopa at Hopa , 41.390 41.429  .

Material used in molecular genetic analysis. ZFMK ICH-TIS-NB186  and NB199, Georgia: Rioni R. drainage: Tskhenitskale River upstream from Samtredia, 42.169 42.431. (Accession numbers: KP 050504, KP 050505, KP 050519; BOLD EUFWF3072-18, MH 795377View Materials, EUFWF4743-18)  .— ZFMK ICH-TIS-K7-1  , Georgia: Galitsga River near Ochamchir, 42.688 41.511. ( BOLD accession number: EUFWF3048-18)  ZFMK ICH-TIS-NB1081  , Georgia: Kelasuri River near Kelasur, 43.006 41.126. ( BOLD accession numbers: BOLD EUFWF3052-18, BOLD EUFWF3053-18) 

Diagnosis. Cobitis satunini  is distinguished from C. saniae  by having the base of the lamina circularis narrowly attached to the pectoral-fin ray (vs. widely connected) and by having roundish or irregularly squarish blotches in Z4 anterior to the dorsal-fin origin (vs. blotches in Z4 horizontally elongate, often very densely set and fused into short or longer stripes).

Distribution. Cobitis satunini  is known from the Georgian Black Sea basin. It is expected to occur also in the tributaries of the adjacent rivers flowing to the Black Sea in Turkey east of Trabzon.

Remarks. Cobitis satunini  is closely related to C. taenia  , especially to the populations from the southern Marmara Sea basin (see below). Based on DNA barcoding it is well separated from all other included Cobitis  and by a minimum K2P distance of 1.6% to C. taenia  from Turkey. Neither the PTP nor the mPTP delimitation approach resolved it as a unique entity but group it together with C. taenia  .

Cobitis taenia  is distinguished from other Cobitis  species in the northern Black Sea basin ( C. elongatoides  , C. taurica  , and C. tanaitica  ) by having 48 chromosomes (vs. 50) ( Janko et al. 2005). To our knowledge, this character has not been studied in C. satunini  and the populations in the southern Marmara Sea basin. These chromosome data are needed to decide if C. satunini  could be a synonym of C. taenia  .

Records of Cobitis  along the southern Black Sea coast are very sparse and we are not aware of findings of Cobitis  (except C. simplicispina  ) between Trabzon in the east (Erk'akan et al. 1999) and Bartın in the west ( C. taenia, Perdices et. al. 2018  ). We examined Cobitis  from Hopa and preliminary identify these as C. satunini  awaiting confirmation from molecular data. We suspect, that Cobitis  from Trabzon, identified as C. splendens  by Erk'akan et al. (1999), might also belong to C. satunini  . This record might have been based on males with a much reduced Z3. We strongly encourage fieldwork in this area to study the distribution ranges of Cobitis  in the southern Black Sea basin.
