Two-cluster test between lineages in these phylogenetic trees has been performed. On the basis of rate constancy, the rate of nucleotide substitutions of 16S rDNA sequence data is estimated as 0.27% per million years. The analysis strongly supports the recognition of the Dorippinae as a monophyletic subfamily. Phylogenetic tree indicates that the subfamily Dorippinae is divided into two main clades, and genus Dorippe appears basal in the subfamily, diverging from other species 36.6 Ma ago. It is also clear that the Heikea is closely related to the genus Neodorippe. The divergence time between them is 15.8 Ma.展开更多
关公蟹属Dorippe系Weber于1795年建立的。Serène and Romimohtarto,1969年主要根据雄性第1腹肢构造的不同,将原关公蟹属分为三属四亚属,即Dorippe(Dorippe),Dorippe(Dorippoides),Neodorippe(Neodorippe),Neodorippe(Nebilum)和Par...关公蟹属Dorippe系Weber于1795年建立的。Serène and Romimohtarto,1969年主要根据雄性第1腹肢构造的不同,将原关公蟹属分为三属四亚属,即Dorippe(Dorippe),Dorippe(Dorippoides),Neodorippe(Neodorippe),Neodorippe(Nebilum)和Paradorippe。在这些属中,关公蟹属和亚属在印度西太平洋区仅记述过一种,即Dorippe(Dorippe)frascone(Herbst)。历年来,我所在全国沿海进行采集和全国海洋综合调查中获得了一些关公蟹标本,其中有两个新种,特报道如下。展开更多
