Abstract

ABSTRACT A new filamentous bangialean alga, Pseudobangia corderoi sp. nov., is described from the northern Philippines. Locally known as a sea vegetable, this species was previously identified as ‘Bangia fuscopurpurea’. Inferred combined analyses of the nucleus-encoded SSU rDNA and the plastid-encoded RubisCO LSU (rbcL) gene indicate that P. corderoi is sister to another unidentified species of Pseudobangia (originally referred to also as ‘Bangia fuscopurpurea’) from Taiwan. Together, these two taxa formed the closest diverging lineage from Pseudobangia kaycoleae (generitype). Current molecular phylogenies have also yielded monophyly of Pseudobangia and strong support for a sister relationship with the ‘Bangia 2’ lineage. Molecular and geographic analyses clearly differentiate P. corderoi from other filamentous Bangiales, whereas morpho-anatomical analysis identified only one distinguishing character, i.e. larger dimensions of the thalli.

摘要报道了菲律宾北部一种新的丝状藻Pseudobangia corderoi sp. nov.。该物种在当地被称为一种海洋蔬菜,以前被确定为“Bangia fuscopurpurea”。对核编码的SSU rDNA和质粒编码的RubisCO LSU (rbcL)基因的推断综合分析表明,P. corderoi是来自台湾的另一种未识别的Pseudobangia(最初也称为' Bangia fuscopurpurea ')的姐妹。这两个分类群共同构成了与Pseudobangia kaycoleae(属型)最近的分化谱系。目前的分子系统发育也显示了Pseudobangia的单系性,并有力地支持了它与' Bangia 2 '谱系的姐妹关系。分子和地理分析清楚地将P. corderoi与其他丝状Bangiales区分开来,而形态解剖分析只确定了一个区别特征,即更大的菌体尺寸。
