Abstract

Abstract. A new species of tubulanid palaeonemertean, Tubulanus izuensis sp. nov., is described as the sixth member of the genus in Japanese waters, based on materials dredged at depths of 244–436 m. It can be differentiated from all the known congeners by the unique burnt-orange dorsal pattern consisting of a median longitudinal stripe and transverse bands on a white ground color. In a maximum-likelihood tree reconstructed with partial sequences of the 16S rRNA, cytochrome c oxidase subunit I, 18S rRNA, 28S rRNA, and histone H3 genes, Tubulanus was not monophyletic, while T. izuensis sp. nov. was more closely related to the type species T. polymorphus Renier, 1804 than some other congeners including T. punctatus (Takakura, 1898), T. rhabdotus Corrêa, 1954, T. sexlineatus (Griffin, 1898), and T. tamias Kajihara, Kakui, Yamasaki & Hiruta, 2015.

日本海域的一种新的深海管藻，Tubulanus izuensis sp.nov.（管藻门：古管藻门）

摘要根据244-436米深度的疏浚材料，一种新的管状古生动物——管状亚种(Tubulanus izuensis sp. nov.)被描述为日本水域中管状亚种属的第六位成员。它可以从所有已知的同族动物中区分出来，因为它独特的焦橙色背纹由中间的纵向条纹和横向条纹组成，底色为白色。在用16S rRNA、细胞色素c氧化酶亚基I、18S rRNA、28S rRNA和组蛋白H3基因的部分序列重建的最大似然树中，Tubulanus不是单系的，而izuensis p. 11 .与模式种T. polymorphus Renier(1804)的亲缘关系比其他同系物包括T. punctatus (Takakura, 1898)、T. rhabdotus Corrêa(1954)、T. sexlineatus (Griffin, 1898)和T. tamias Kajihara, Kakui, Yamasaki & Hiruta, 2015)更为密切。
