(GenBank accession numbers: KJ554595, KJ554796, KJ554948).   Diagnosis.  Seminemacheilus ispartensisis distinguished from  S. lendliiby having deeply embedded and isolated oval scales on the caudal peduncle (vs. body scaleless); a very short head (head length 21–24% SL vs. 25–28% SL), a narrower caudal peduncle (10–12% SL vs. 12–16% SL; caudal peduncle depth 1.3–1.6 times in caudal peduncle length (vs. 1.1–1.2), and a shorter predorsal (50–54% SL vs. 53–57) and prepelvic length (52–56% SL vs. 56–59).   Distribution.  Seminemacheilus ispartensisis very widespread in Lake Eğirdir basin and it is also found in the stream Değirmendere, a tributary of the Lake Salda. In addition, Bănărescu & Nalbant (1964)also recorded  Seminemacheilus(as  S. lendlii) from Karapınar (Lake Yarışlı basin), from where it seems to have disappeared as Karapınar dried out. This locality was in the middle of the known range of  S. ispartensis(between Lake Salda and Lake Eğirdir).   Remarks.Based on DNA barcoding,  S. ispartensisis very closely related to  S. lendlii, and the minimum K2P distance between  S. ispartensisand  S. lendliiis only 0.1%. Due to this very close relationship, it is not recovered as a distinct species in the PTP and mPTP delimitation approaches. However, we recognizse  S. ispartensisas a valid species as it is well differentiated from  S. lendliiby the morphological characters given in the diagnosis above. We suspect that introgressive hybridisation of  S. lendliiinto  S. ispartensisor vice versamight have recently occurred; more research is needed to resolve this case.  Erk’akan et al.(2007)gave 37°38’N 30°31’E(= 37.6333, 30.5166) as the typelocality of  S. ispartensis. However, there is no perennial surface water at this location and it is not situated along the road between Eğirdir and Isparta. There might be a lapsus in the coordinates given by Erk’akan et al.(2007), similar to several other erroneous coordinates in the same study as discussed in detail by Kottelat (2012). 5132422306 FFR Turkey 37.8725 stream Sevincbey 6 km southwestern of Egirdir 6 30.7794 Sevincbey 8 485 FFR 15565 1 Isparta prov. 5132422329 FFR Turkey 37.8725 stream Degirmendere, south- western shore of the Lake Salda 6 30.7794 Sevincbey 8 485 FFR 15563 1 Burdur prov. 5132422333 FSJF Turkey 37.8725 stream Degirmendere, southwestern shore of Lake Salda 6 30.7794 Sevincbey 8 485 FFR 15512 1 Burdur prov. 5132422312 FSJF Turkey Caykoy 37.8725 lower stream Caykoy at Koysazi bridge, southeast of Egirdir 6 30.7794 Sevincbey 8 485 FSJF 2473 1 Isparta 5132422324 FSJF Turkey Caykoy 37.8725 stream Ozdere at Egirler village, 8 km northeast of Gelendost 6 30.7794 Sevincbey 8 485 FSJF 3095 1 Isparta prov. 5132422331 FSJF Turkey Ozdere 38.1976 stream Ozdere at Egirler village, 8 km northeast of Gelendost 6 31.1074 Egirler village 8 485 FSJF DNA-1536 1 Isparta prov.
