A new species of poecilostomatoid copepod, Doridicola indistinctus n. sp. (Rhynchomolgidae), is described from specimens found in association with the soft coral Gersemia fruticosa Sars (Alcyonacea: Nephtheidae), collected from the White Sea. The new species is distinguished from its congeners by the combination of the following features in the female: (i) antenna tipped, with two subequal large claws which are about as long as the segment bearing them; (ii) two naked, extremely unequal setae on the middle segment of the maxilliped, the short, medial seta less than half-length of the outer seta; and (iii) free segment of leg 5 bears the basal swelling and is ornamented with spinules on the outer surface. This is the first report of a copepod occurring in symbiosis with nephtheid corals from the Arctic Zone. It also constitutes the northernmost record for a species of Doridicola Leydig, 1853, which is the largest genus of the Rhynchomolgidae Burmeister, 1835 comprising 52 species, including the present new species.
一种新的拟哲水蚤类桡足类动物，模糊多枝哲水蚤 Doridicola indistinctus n. sp.（吻软哲水蚤科），是根据在与软珊瑚弗氏肉芝软珊瑚 Gersemia fruticosa Sars（海鸡冠目：肾形珊瑚科）共生的标本中发现的样本描述的，这些样本采自白海。该新物种在雌性个体中具有以下特征组合，从而与同属其他物种相区分：（i）触角顶端有两个大小近似的大爪，其长度约与着生它们的节段长度相等；（ii）颚足中间节段有两根裸露且极不相等的刚毛，较短的内侧刚毛长度不到外侧刚毛的一半；（iii）第 5 对步足的游离节段有基部肿胀，外表面有小刺。这是首次报道一种桡足类动物与北极地区的肾形珊瑚共生。这也构成了 1853 年莱迪格多枝哲水蚤属物种最北的记录，该属是 1835 年布迈斯特吻软哲水蚤科中最大的属，包含 52 个物种，包括当前的新物种。
