摘要
相手蟹科的诸多种类因其形态极其相似成为方蟹总科分类中疑问较多的一个类群。通过对中国沿海相手蟹线粒体COI和16S rRNA基因序列进行分子系统发育分析,结果表明14种相手蟹COI和16S rRNA基因序列之间差异分别为5.7%~14.5%和1.5%~12.1%,均达到了种间差异水平。构建的系统发育树显示,14种相手蟹分别为独立有效物种,但分属于拟相手蟹属和近相手蟹属的4种拟相手蟹和3种近相手蟹,没有分别形成2个独立的支系,而是混合聚成一大支系。而属于螳臂相手蟹属的无齿螳臂相手蟹则首先与属于中相手蟹属的中华中相手蟹聚成一支,再与红螯螳臂相手蟹聚为一大支,表现出与形态分类的不一致。错综复杂的分子系统关系预示着相手蟹类为多系起源,也表明它们之间的种间关系乃至于属间关系尚有诸多问题有待进一步厘定。
The species in the family of Sesarmidae are among the species mostly difficult to be differentiated taxonomically in the Superfamily Grapsoidea because of their morphological similarity. The analysis of partial sequences of mitochondrial COI gene and 16 S rRNA gene of 14 species in 8 genera of Sesarmidae for their molecular phylogenetics reveals that the percentages of sequence divergences of 14 species of Sesarmidae are from 5.7% to14.5% and from 1.5% to 12.1%, both indicating that the species difference are significant. The phylogenetic trees show that the 14 species are separate and valid species and 4 species of Parasesarma and 3 species of Perisesarma are not 2 independent clades but clustered into 1 clade. Chiromantes dehaani and Sesarmops sinensis are clustered into one clade and then clustered with C. haematocheir into another clade, inconsistent with their morphological classification. The complicated molecular phylogenetic relationship among the species of Sesarmidae suggests that the species in the family of Sesarmidae might have polyphyletic origin, and their interspecific relationship or intergenus relationship need to be clarified.
