Common name. Bithynian spined loach.
Diagnosis. Distinguished from other species of Cobitis in Black Sea basin and endorheic Anatolian basins of Lakes Akşehir, Eber and Ilgın by: ○ pigmentation in Z3 reduced to about head length in male or pigmentation in Z3 as wide as or narrower than pigmentation in Z2 / ○ blotches in Z4 irregularly roundish or squarish anterior to dorsal origin / ○ focal zone of subdorsal scale small, about 1⁄3–1 ⁄10of verti - cal scale diameter / ○ one lamina circularis in male / ○ base of lamina circularis with a narrow connection to pectoral ray. Size up to 86 mm SL.
Distribution. Türkiye: Small coastal streams around Akçakoca and Büyük Melen (Black Sea).
Habitat. Lower and middle reaches of still to moderately fast-flowing, clear streams with mud or sand bottoms.
Biology. No data.
Conservation status. LC; Population may be stable, but more data is needed.
Cobitis strumicae ; Provadiskaya, Bulgaria; ~ 70 mm SL.
Remarks. Doubtful records of this species from Aegean and southern Marmara basins could not be confirmed and seem to be based on misidentifications of C. satunini and C. fahireae . A reduced pigmentation in Z 3 in male is very characteristic to C. splendens . Still, this character state is not unique to C. splendens , and individual males with very much reduced or even no pigmentation in Z3 are found in many other Cobitis species. Cobitis from the Büyük Melen [entering Black Sea at 41.073, 30.967] are identified as C. splendens based on molecular characters. Still, in this population, the pigmentation in Z3 is not reduced, distinguishing it from C. splendens . The Cobitis of Anatolian Black Sea basin needs an in-depth revision.
