Abstract

ABSTRACT Phylogenetic analyses resolved that specimens from Manawatāwhi/Three Kings Islands in northern New Zealand, formerly identified as Sonderophycus coriaceus, belong to the genus Agissea (Peyssonneliales). This species is dark red, prostrate and robust, with leathery, fan-shaped lobes and is described here as Agissea teruruhau. It was found to serve as a host to a very small red algal epiphyte described here as Piriora waewaiti gen. & sp. nov. While phylogenetic analyses have placed Piriora in the Gigartinales, the familial placement of this genus has been unable to be resolved. Manawatāwhi/Three Kings Islands is a group of small islands known to harbour a rich marine biota with many endemic species, and the description of these taxa has increased the reported endemic algal flora of the islands. In addition, the phylogenetic analyses have confirmed the presence of Olokunia boudouresquei and a further three species of Peyssonneliales in the New Zealand flora, belonging to the genera Olokunia, Peyssonnelia and Seiria.

Agissea teruruhau sp.nov.（Peyssonneliales，Rhodophyta）和新西兰Manawatāwhi的附生植物Piriora waewaeiti gen.&sp.nov..（Gigartinales，Rhodaphyta）

摘要系统发育分析表明，来自新西兰北部马纳瓦蒂群岛/三王群岛的标本，以前被鉴定为珊瑚藻属，属于Agissea属（Peyssonneliales）。该物种呈暗红色，匍匐，健壮，有坚韧的扇形裂片，在这里被描述为特鲁鲁乌。它被发现是一种非常小的红藻附生植物的宿主，在这里被描述为Piriora waewaiti gen.&sp.nov.虽然系统发育分析将Piriora放在了Gigartinales中，但该属的家族位置尚无法确定。Manawatāwhi/三王群岛是一组小岛，已知拥有丰富的海洋生物群和许多特有物种，对这些分类群的描述增加了据报道的岛屿特有藻类区系。此外，系统发育分析证实了新西兰植物区系中存在Olokunia boudouresquei和另外三种Peyssonneliales，属于Olokonia、Peyssonnellia和Seiria属。
