Sažetak
Using morphometric, meristic and qualitative characters, we confirmed a specific status of a clade discovered based on molecular data only. The newly described species Phoxinus krkae has a very local distribution in the upper Krka River but is easily morphologically distinguished from geographically neighbouring species with much wider ranges: Phoxinus lumaireul, Phoxinus marsilii and Phoxinus csikii. Phoxinus krkae is well differentiated in statistical analyses and differs from other species of Phoxinus in northern Adriatic Sea drainages and right‐bank tributaries of the middle and lower River Danube by a combination of characters, none of them unique: caudal peduncle length 1.9–2.2 times minimum depth of caudal peduncle ; upper lip not projecting beyond lower lip ; rostral fold absent ; total number of scales in lateral series 74–84 ; lateral line incomplete and interrupted, commonly 17–49 (< 60% of total number of scales in lateral series) with no or few canal segments on posterior body and caudal peduncle ; scales on belly extending forward to over middle of distance between pelvic‐fin base and pectoral‐fin origin ; patches of breast scales commonly connected by scattered scales or forming 1–3 regular rows of scales ; total vertebrae commonly 38–39 (22 + 17, 22 + 16 or 21 + 17). The study reveals unrecognised morphological diversity within the group and provides the groundwork for future taxonomic study in Phoxinus in the Adriatic region and the Danube Basin.
