Romanogobio skywalkeri, new species, is described from the upper Mur River in the Austrian Danube drainage. It is related to R. banarescui from the Mediterranean basin. Romanogobio skywalkeri is distinguished from R. banarescui by lacking epithelial crests on the predorsal back, having 12-14 total pectoral-fin rays (vs. 10-11) and usually 8½ branched dorsal-fin rays (vs. 7½). It is distinguished from other Romanogobio species in the Danube drainage by having a very slender body; a moderately long barbel, extending slightly beyond the posterior eye margin; and no epithelial crests on the predorsal back. Romanogobio skywalkeri is distinguished by a minimum net divergence of 6.3% (uncorrected p-distance against R. banarescui) in the COI barcoding region from other European Romanogobio species. A key to the Romanogobio species of the Danube drainage is provided. Romanogobio banarescui from the Vardar drainage and R. carpathorossicus from the Danube drainage are treated as valid species.
斯凯氏罗马诺戈比鱼，新物种，由奥地利多瑙河流域穆尔河上游描述而来。它与地中海盆地的巴纳雷斯库氏罗马诺戈比鱼相关。斯凯氏罗马诺戈比鱼与巴纳雷斯库氏罗马诺戈比鱼的区别在于：背前部无上皮嵴，胸鳍总鳍条12 - 14根（相比之下为10 - 11根），背鳍分支鳍条通常为8½根（相比之下为7½根）。它与多瑙河流域的其他罗马诺戈比鱼物种的区别在于：身体非常细长；须适度长，略超出眼后缘；背前部无上皮嵴。斯凯氏罗马诺戈比鱼在细胞色素氧化酶亚基I（COI）条形码区域与其他欧洲罗马诺戈比鱼物种的最小净分歧为6.3%（与巴纳雷斯库氏罗马诺戈比鱼的未校正p距离）。提供了多瑙河流域罗马诺戈比鱼物种的检索表。瓦尔达尔河流域的巴纳雷斯库氏罗马诺戈比鱼和多瑙河流域的喀尔巴阡罗马诺戈比鱼被视为有效物种。
