臀鳍软条: 12 - 13. Can be distinguished from other species of Cottus in the Adriatic basin and Danube drainage by the combination of the following characters; no distinct transverse bands on pelvic fin; prickling on body under pectoral fin, very rarely present shortly behind pectoral fin; depth of caudal peduncle 25-31% HL, 1.0-1.7 times in its length; body depth at origin of second dorsal fin 17-23% SL; interorbital distance 0.7-1.4 times in eye diameter; 15-16 1/2 rays in second dorsal fin; 12-13 1/2 anal-fin rays; last anal-fin ray connected to body by a membrane along 1/3-1/2 of its length; no membrane attaching pelvic-fin base to body; membrane of first dorsal fin usually not reaching origin of second dorsal fin in females; dorsal head length 21-25% SL; predorsal length 35-40% SL; distance from tip to snout to origin of second dorsal fin 54-59% SL (Ref. 55856).
能被与亚得里亚海流域与多瑙河流域的其他种的 Cottus 区分藉由下列特征的组合; 没有在腹鳍上的明显的横纹; 在胸鳍下面的身体上刺, 很少地存在的紧跟在胸鳍之后; 尾柄 25-31% HL 的深度, 1.0-1.7 倍于体长; 在第二背鳍起点 17-23% SL 的体高; 眼间距 0.7-1.4 倍眼直径; 在第二背鳍鳍的 15-161/2个鳍条; 12-131/2个臀鳍棘条; 连接到身体的最后臀鳍鳍条经由一个膜沿着它的长度中的 1/3-1/2; 没有薄膜对身体的附属腹鳍基底; 第一背鳍的薄膜通常在雌性中不達到第二背鰭起點; 頭部背面長度 21-25% SL; 前背的長度 35-40% SL; 從到吻的頂端到第二背鰭起點 54-59% SL 的距離.(參考文獻 55856)
