Cobitis strumicae  Karaman, 1955

( Fig. 26–27View FIGURE 26View FIGURE 27)

Cobitis taenia strumicae  Karaman, 1955: 190, fig. 4 (type locality: FYROM: Monospitovo swamp and Strumica River )  .

Cobitis peschevi Sivkov & Dobrovolov, 1984: 1673  , fig. 1 (type locality: Bulgaria: Eleshnitsa River, a tributary of Kamchiya River).

Material examined. FSJF 1703, 12, 50–69 mm SL; Greece: stream Kompsatos at Polyanthos , 41.139 25.212  .— FSJF 1755, 28, 44–81 mm SL; Greece: stream Maritza at Kornofolia , 41.134 26.292  .— FSJF 2343, 7, 49–95 mm SL; Turkey: Çanakkale prov.: stream Koca at Bakacak , 40.204 27.086  .

Material used in molecular genetic analysis. ZFMK ICH-TIS 55817 & 55818; Greece: Strymon River near Amfipolis, 40.829 23.839. (GenBank accession numbers: KJ 553048View Materials, KJ 553143View Materials).— FSJF DNA- 301; Turkey: Çanakkale prov.: stream Koca at Bakacak, 40.204 27.086. (BOLD accession number: EUFWF 4175-18).

Diagnosis. Cobitis strumicae  is distinguished from all other species of Cobitis  in the Middle East by having two brown blotches at the upper and lower margin of the caudal-fin base (vs. no spot or one spot). It is further distinguished from C. fahireae  from the Aegean Sea basin, C. puncticulata  from the Marmara Sea basin as well as from C. taenia  from the southern Black and Marmara Sea basins by having two laminae circularis in the male (vs. one). Cobitis strumicae  is distinguished from C. dorademiri  and C. phrygica  , both having two laminae circularis in the male, by lacking the pigmentation below Z4 (vs. present in C. dorademiri  , blotches in Z4 often dissociated into a field of spots and blotches, especially in the female C. phrygica  ) and having a bifurcate suborbital spine (vs. simple in C. phrygica  ).

Distribution. Cobitis strumicae  is widespread in the European Aegean and southern Black Sea basins, from the Struma River drainage to the area of Varna ( Greece, Bulgaria, and Turkey), the Lakes Volvi and Koronia ( Greece) and the Danube drainage in Bulgaria. Cobitis  from the stream Koca at the Biga Peninsula (northernmost Aegean basin in Turkey) are identified as this species.

Remarks. Molecular data ( Fig. 1View FIGURE 1) suggest that C. strumicae  is not closely related to other Cobitis  species having two laminae circularis except of C. afifeae  described below and C. punctilineata  known from the northern Aegean Sea basin in Greece. Based on DNA barcoding it is well separated from all other included Cobitis  and by a minimum K2P distance of 5.3% to C. punctilineata  . It is also supported by the PTP and mPTP delimitation approaches.

See below for details to distinguish C. strumicae  from C. afifeae  and from other Cobitis  species found in the southern Marmara Sea basin. Cobitis strumicae  is reported here for the first time from Asia. Its occurrence on the Biga Peninsula is no surprise as C. strumicae  is well known from the adjacent northern Aegean and Marmara Sea basins.
