本文首次在日本南部小笠原群岛和马尾岛约30 m深的海域，通过挖泥采集标本，报道了最近在夏威夷发现的一种深海ulvaca umbraulva kuaweuweu的生殖结构、早期发育和类胡萝卜素成分。虽然在美国，黄质是黄质。日本的一种特有的类胡萝卜素，向日葵，含有α-胡萝卜素和β-胡萝卜素。华为与华为明显不同。日本菌体形态与生殖结构：细胞形态、菌体上部内根状丝的存在与缺失、实心菌体/部分囊状菌体以及类动物的发育过程。叶绿体cl和tufa基因的多基因串联DNA序列，以及细胞核18S、5.8S、28S rDNA和rDNA ITS1、ITS2区域显示u分离。来自于由peu类组成的进化支。日本稻、日本稻、日本稻和日本稻。kaloakulau。综上所述，基于其独特的形态、生活史、类胡萝卜素组成和分子系统发育，我们建议建立一个新属ryuguphycusgen。11 .容纳；kuaweuweu, asR。kuaweuweucomb。11月。
The reproductive structures, early development and carotenoid composition ofUmbraulva kuaweuweu, which is a deep-water ulvacean species recently reported from Hawaii, are reported for the first time using the specimens collected by dredging at ~30 m depth from Ogasawara Islands and Mageshima in southern Japan. AlthoughUmbraulva kuaweuweuhad siphonaxanthin as inU. japonica, a characteristic carotenoid ofUmbraulva, U. kuaweuweulacked α-carotene and β-carotene.U. kuaweuweudiffered markedly fromU. japonicain thallus morphology and reproductive structures: cell shape, presence/absence of inner rhizoidal filaments in the upper parts of thalli, solid/partly saccate thalli, and developmental processes of zoids. Multigene concatenated DNA sequences of chloroplastrbcL andtufA genes, and nuclear 18S, 5.8S, 28S rDNA and rDNA ITS1 and ITS2 regions indicated separation ofU. kuaweuweufrom the clade comprised of the generitypeU. japonica, U. amamiensis, U. dangeardiiandU. kaloakulau. In conclusion, based on the distinctive morphology, life history, carotenoid composition and molecular phylogeny, we propose the establishment of a new genusRyuguphycusgen. nov. to accommodateU. kuaweuweu, asR. kuaweuweucomb. nov.
