Cottus gratzianowi sp. nov. is distinguished from C. koshewnikowi by a larger eye (horizontal diameter 23−28% HL, equal to or exceeding snout length vs. 16−25% HL, less than snout length), a rounded caudal fin (vs. commonly truncated), ... : Published as part of Sideleva, Valentina G., Naseka, Alexander M. & Zhidkov, Zakhar V., 2015, A new species of Cottus from the Onega River drainage, White Sea basin (Actinopterygii: Scorpaeniformes: Cottidae), pp. 419-430 in Zootaxa 3949 (3) on pages 420-430, DOI: 10.11646/zootaxa.3949.3.7, http://zenodo.org/record/243672 ... |
