A new genus and species of copepod, Jasmineiricola mackiei n. gen. et n. sp., parasitic on at least three species of the sabellid polychaete genus Jasmineira Langerhans, 1880 is described. The adult female is mesoparasitic, living with part of its body (the endosoma) embedded within the host and part (the ectosoma) protruding through the host's body wall. The endosoma consists of a well defined head region carried anteriorly on the trunk which has paired lateral lobes housing the ovaries. The head bears a rosette-like array of eight slender lobes, which are probably derived from the mouthparts. The only limbs present on the trunk are the subchelate maxillipeds positioned immediately posterior to the head. The ectosoma consists of a posterior genito-abdominal lobe bearing paired genital apertures. The male is unknown. The new genus cannot be placed in any of the five existing families of mesoparasitic copepods on polychaete hosts and is treated as the type of a new monotypic family, the Jasmineiricolidae. The new species occurs over a depth range from 19 to 279 m, and is widely distributed from UK coastal waters to Norwegian waters inside the Arctic Circle.
描述了一种新的桡足类属和种,即茉莉寄生桡足虫(Jasmineiricola mackiei),它寄生于至少三种1880年兰格汉斯(Langerhans)命名的茉莉沙蚕属(Jasmineira)多毛纲动物。成年雌性为中寄生性,其身体一部分(内体)嵌入宿主体内,另一部分(外体)从宿主身体壁突出。内体由一个界限分明的头部区域组成,头部位于躯干部前方,躯干部有成对的侧叶,卵巢位于其中。头部有一个由八个细长叶组成的玫瑰花结状排列,这些叶可能源自口器。躯干部上仅有的附肢是位于头部后方紧邻处的亚螯状颚足。外体由一个带有成对生殖孔的后生殖腹部叶组成。雄性未知。这个新属不能归入现有的五个多毛纲宿主中寄生性桡足类科中的任何一科,被视为一个新的单型科——茉莉寄生桡足科(Jasmineiricolidae)的模式属。新物种分布在19至279米的深度范围内,从英国沿海水域到北极圈内的挪威水域广泛分布。
