Abstract

is described as a new genus pertaining to the family Dendrophylliidae (Anthozoa, Scleractinia) based on specimens from Cape Verde, eastern Atlantic. This taxon was first recognized as and later described as a new species, , which then changed the status of the genus as native to the Atlantic Ocean. Here, based on morphological and molecular analyses, we compare fresh material of to other dendrophylliid genera and describe it as a new genus named in order to better accommodate this species. Evolutionary reconstruction based on two mitochondrial and one nuclear marker for 67 dendrophylliids and one poritid species recovered as an isolated clade not related to and more closely related to and . differs from by having a phaceloid to dendroid growth form with new corallites budding at an acute angle from the theca of a parent corallite. The genus also has normally arranged septa (not Portualès Plan), poorly developed columella, and a shallow-water distribution all supporting the classification as a new genus. Our results corroborate the monophyly of the genus and reiterate the Atlantic non-indigenous status for the genus. In the light of the results presented herein, we recommend an extensive review of shallow-water dendrophylliids from the Eastern Atlantic.

摘要

基于来自东大西洋佛得角的标本,被描述为鹿角珊瑚科(珊瑚虫纲,石珊瑚目)的一个新属。这个分类单元最初被认定为……,后来被描述为一个新物种……,这改变了……属原产于大西洋的地位。在此,基于形态学和分子分析,我们将……的新鲜材料与其他鹿角珊瑚属进行比较,并将其描述为一个名为……的新属,以便更好地容纳这个物种。基于两个线粒体标记和一个核标记对67种鹿角珊瑚和一个鹿角杯形珊瑚物种进行的进化重建,将……恢复为一个孤立的分支,与……无关,且与……和……关系更密切。……与……的不同之处在于,其具有从亲代珊瑚虫的外壁以锐角生出新珊瑚虫的丛状到树状生长形式。该属还具有正常排列的隔膜(非波尔图阿莱斯平面)、发育不良的中轴柱以及浅水分布,所有这些都支持将其分类为一个新属。我们的结果证实了……属的单系性,并重申了该属在大西洋的非本土地位。鉴于本文给出的结果,我们建议对东大西洋的浅水鹿角珊瑚进行广泛的重新审视。
