中国珊瑚藻分类与分布名录(珊瑚藻亚纲：珊瑚藻目，混石藻目，孢石藻目)

A Checklist for the Classification and Distribution of Coralline Algae in China (Corallinophycidae: Corallinales, Hapalidiales, Sporolithales)

摘要: 我国是世界上生物多样性最高的国家之一。然而迄今为止还没有一个涵盖全国范围的珊瑚藻系统分类和分布名录。本文收集了涉及中国珊瑚藻分类和分布的文献，采用国际上最新的珊瑚藻亚纲下珊瑚藻种类分类系统，通过系统整理，汇编成中国珊瑚藻分类与分布名录。主要修订有：1) 珊瑚藻目分类单元升级为珊瑚藻亚纲(Corallinophycidae)，原包括的三个科级单元分别升级为珊瑚藻目(Corallinales)，混石藻目(Hapalidiales)和孢石藻目(Sporolithales)；2) 修订了53种同物异名种；3) 补充了一个新属(壳状藻属Crustaphytum)和一新种(太平洋壳状藻C. pacificum)。本名录共收录了截止到2018年10月记述的所有珊瑚藻种类，共计3目10科26属112种，约占世界已接受种类数量的15%。其中，珊瑚藻目包括7科20属99种，混石藻目包括2科4属9种，孢石藻目包括1科2属4种。对沿海各省珊瑚藻的分布分析发现，台湾省是我国珊瑚藻物种多样性记录最丰富的省份，已记述23属66种；其次为海南(14属41种)。本名录全面概括了中国珊瑚藻类的分类和分布，可为深入开展全国范围的珊瑚藻类生物多样性研究与保护提供科学依据。

Abstract: China is one of the countries with highest biodiversity in the world. However, due to recent and rapid discoveries of coralline algae (CA) species in China, there is no nationwide systematic and checklist of the classification and distribution of CA. This paper collected literatures about the classification and distribution of CA species in China, adopted the updated classification system of CA in the world, and compiled the list of classification and distribution of CA species in China through systematic arrangement. The major changes in the new version of the inventory are as follows: 1) the original taxon was upgraded to Corallinophycidae, and the three family units were upgraded to Corallinales, Hapalidiales and Sporolithales respectively; 2) 53 homonyms were re-vised; 3) a new genus (Crustaphytum) and a new species (C. pacificum) were added. A total of 112 species of coral algae belonging to 26 genera, 10 families and 3 orders, were recorded in this checklist as of October 2018, accounting for about 15% of the world’s accepted species. Among them, Corallinales includes 7 families, 20 genera and 99 species; Hapalidiales includes 2 families, 4 genera and 9 species; Splithales includes 1 family, 2 genera and 4 species. According to the analysis of the distribution of CA in China coastal provinces, Taiwan has the richest record of species diversity of CA with described 23 genera and 66 species, followed by Hainan (14 genera and 41 species). This checklist comprehensively summarizes the classification and distribution of CA spe-cies in China, which can provide a scientific basis for conducting intensive research and protection of the biodiversity of CA in our country.
