Diagnosis. Barbus anatolicus IS DIStINGUIShED FROM B. rionicus AND B. escherichii BY hAVING MORE LAtERAL LINE SCALES (58–71 VS. 51–58 IN B. rionicus; 52–58 IN B. escherichii) AND thE OUtER MARGIN OF thE DORSAL FIN BEING MARKEDLY CONCAVE (VS. StRAIGht OR SLIGhtLY CONCAVE). It IS ALSO DIStINGUIShED FROM B. escherichii BY thE LENGth OF thE ANAL FIN BEING EqUAL IN BOth SEXES (VS. LONGER IN FEMALE thAN IN MALE). Barbus anatolicus IS FURthER DIStINGUIShED FROM B. rionicus BY hAVING A MORE OSSIFIED LASt UNBRANChED DORSAL-FIN RAY (OSSIFIED APPROXIMAtELY 70–80% OF ItS LENGth VS.

Distribution and notes on habitat. Barbus anatolicus IS KNOWN FROM thE DRAINAGES OF thE KIZILIRMAK AND YEŞILIRMAK RIVERS (FIGURE 8). It INhABItS SWIFt FLOWING WAtER, WIth ROCKY AND PEBBLE BOttOM.
Etymology. ThE NAME OF thE SPECIES IS DERIVED FROM ANAtOLIA. AN ADjECtIVE.
Remarks. Barbus anatolicus IS DIStINGUIShED FROM B. niluferensis FROM thE SOUthERN MARMARA SEA BASIN BY hAVING MORE GILL RAKERS (9–11 VS. 6–8), MORE tOtAL VERtEBRAE (45–49 VS. 43–44), A LONGER (26–29% SL VS. 24–26) AND MORE SLENDER hEAD (hEAD DEPth At OCCIPUt 50–61% HL VS. 60–68) AND A ShORtER DIStANCE BEtWEEN thE ROStRAL BARBELS (8–13% HL VS. 18–23). Barbus anatolicus IS DIStINGUIShED FROM B. pergamonensis FROM thE EAStERN AEGEAN SEA BASIN BY hAVING MORE tOtAL VERtEBRAE (45–49 VS. 41–42), MORE LAtERAL LINE SCALES (58–71 VS. 52–61), A LONGER hEAD (26–29% SL VS. 25–26) AND A ShORtER DIStANCE BEtWEEN thE ROStRAL BARBELS (8–13% HL VS. 19–22).
Barbus anatolicus IS DIStINGUIShED FROM B. lacerta FROM thE PERSIAN GULF BASIN AND FROM B. cyri, FROM thE CASPIAN SEA BASIN BY hAVING A StRONGLY OSSIFIED LASt UNBRANChED DORSAL-FIN RAY (OSSIFIED ALONG 70–80% OF ItS LENGth VS. LESS thAN 50%) AND thE LOWER LIP WIth A MEDIAN LOBE (VS. A POORLY DEVELOPED SWOLLEN MEDIAN PAD). It FURthER DIFFERS FROM B. lacerta AND B. cyri BY hAVING MORE tOtAL VERtEBRAE (45–49 VS. 42–44) AND MORE GILL RAKERS ON thE OUtER SIDE OF thE FIRSt GILL ARCh (9–11 VS. 6–9). It hAS tO BE NOtED, thAt WE FOUND NO EXtERNAL DIFFERENCE tO DIStINGUISh B. lacerta, B. cyri AND B. karunensis FROM EACh OthER AND WE CANNOt CONFIRM thE MORPhOLOGICAL PARt OF thE DIAGNOSES PROVIDED BY KhAEFI et al. (2017) PARtLY BASED ON thE SAME MAtERIALS EXAMINED AS FOR thIS StUDY.
