我们收集了深水种Rhodymenia prostrata(Rhodymeniaceae,红藻门),近50年来首次,从模式产地Mageshima岛,日本。结合rbcL、cox 1和28S rDNA的分析结果表明,R.在Halopeltis属中,它是一个匍匐的,但与所有其他Halopeltis种不同。然而,双名Halopeltis prostrata已经存在,因此需要一个新的绰号。因此,我们建议将其命名为Halopeltis tanakaeforR.基于形态解剖学和分子分析。H. tanakae与Halopeltis的属概念一致。Halopeltis tanakaeis的特征是叶状体平卧,叶片卷曲,囊果基部无缢痕,囊果主要在叶片边缘,囊果腔中有粘液丝,Halopeltis tanakaeis是该属在西北太平洋的第二个代表。
We collected the deep-water speciesRhodymenia prostrata(Rhodymeniaceae, Rhodophyta), for the first time in nearly 50 years, from the type locality off Mageshima Island, Japan. Our combinedrbcL,cox1 and 28S rDNA analyses suggested thatR. prostratabelongs in the genusHalopeltisbut is distinct from all otherHalopeltisspecies. However, the binomialHalopeltis prostrataalready exists and hence a new epithet was required. Consequently, we propose the new nameHalopeltis tanakaeforR. prostratabased on morpho-anatomical and molecular analyses. The occurrence of small intercalating cells inH. tanakaeis congruent with the generic concept ofHalopeltis. Halopeltis tanakaeis characterized by a procumbent thallus, crispate blades, cystocarps lacking basal constrictions, cystocarps primarily on blade margins, and mucilaginous strands in cystocarp cavities.Halopeltis tanakaeis the second representative of the genus to be reported from the northwestern Pacific.
