Abstract

Shortcrevice eelpout Gymnelopsis brevifenestrata (Zoarcidae, Gymnelinae) is an endemic species of the Sea of Okhotsk; until recently, it was known by 12 type specimens from the museum collections. The variability of the species was characterized and its distribution was revised by the study of several new specimens and paratypes. The live coloration of males is described for the first time, giving new characters for the field taxonomic identification of this species. G. brevifenestrata inhabits the western and northern Sea of Okhotsk at the depth range of 76–200 m. Considering the association of G. brevifenestrata to supercooled waters, it should be assigned to the glacial group of Okhotsk-sea species.

鄂霍次克海短缝鳗鱼Gymnelopsis brevifenestrata（Zoarcidae）的新数据

摘要

Shortcrevice溢水藻（Gymnelopsis brevifenestrata）（鄂科底亚科（Gymnelinae））是鄂霍次克海的特有物种。直到最近，博物馆藏品中的12个类型标本才使它为人所知。通过研究几个新的标本和亚型，对该物种的变异性进行了表征，并对其分布进行了修改。首次描述了雄性的活体颜色，为野外生物分类识别提供了新的特征。G. brevifenestrata栖息在鄂霍次克海西部和北部，深度范围为76–200 m。考虑到G. brevifenestrata与过冷水有关，应将其归入鄂霍次克海物种的冰川群。
