Sažetak
Including description of two new species, ten Phoxinellus species are reported from Croatia and Bosnia-Herzegovina. Phoxinellus krbavensis, new species, and Phoxinellus jadovensis, new species, together with P. adspersus and P. ghetaldii, constitute a group which is characterized by an irregular spotted color pattern, an elongate caudal peduncle, a large postcleithrum, an increased number of precaudal anal-fin pterygiophores, and the presence of a large genital papilla in females. P. krbavensis also differs from all congeners in having a short, highly interrupted lateral line formed from small, separated poorly ossified scales, commonly 20–40, extremely reduced body scales, a very short V-A distance, and the highest number of gill rakers (usually 11). P. jadovensis is distinguished from the other species of the group in having a conical slightly pointed snout, a terminal mouth, body scales embedded, poorly ossified, and spaced, and a long lateral line, commonly 51–60 total scales. P. pstrossii, described from the Trebišnjica River is tentatively considered to be a synonym for P. ghetaldii.
P. fontinalis, a poorly-known striped Phoxinellus, differs from all other species of the genus in particular by having a strongly laterally compressed, humped body with a straightened ventral profile and a short caudal peduncle, well developed scales, an incomplete interrupted lateral line with (17)23–37(56) total scales, terminating in the area between the pectoral and anal fins, and a rel-atively elongate abdominal vertebral region, total count usually 23+16 or 23+17 with numerous both predorsal (15) and intermediate (5) vertebrae.
