cisstopus chinensis sp. 11 .是一种小型底栖章鱼。cisstopus属的主要诊断特征是在蛛网的口腔表面有八个粘膜袋，其中一个位于每个臂基之间。本文研究了东海和南海的中国栗鼠（Cistopus chinensis sp. 11 .）的形态特征。成年雄鼠吸盘较大，正常臂和异子叶臂吸盘数较低，可将中国cisstopus与印度cisstopus和台湾cisstopus区分。成年雄性ⅰ、ⅱ和ⅳ臂上的第10和/或第11个吸盘增大。成熟的雌虫产大卵。从6个中国鼠的线粒体细胞色素c氧化酶亚基I （COI）基因中获得了长度为658个碱基对的片段，碱基频率分别为A = 0.3050, c = 0.1991, G = 0.1418和T = 0.3541。A + T含量为65.91%。两个单倍型在305位点（a→G）有一个单核苷酸转移。新种个体间的遗传距离为0.000 ~ 0.002。遗传距离最近的分类群为籼稻（0.118 ~ 0.121），最远的分类群为台湾稻（0.124 ~ 0.126）。高引导支持cisstopus井的单性（引导最大似然91%，邻居加入89%，最大简约83%）。
Cistopus chinensis sp. nov. is a small benthic octopod. The primary diagnostic character for the genus Cistopus is the possession of eight mucous pouches set in the oral surface of the webs, with one located between each of the arm bases. This study describes the morphological characters of Cistopus chinensis sp. nov. from the East China Sea and the South China Sea. Cistopus chinensis sp. nov. can be distinguished from Cistopus indicus and Cistopus taiwanicus by enlarged suckers in mature males and lower sucker counts on normal arms and the hectocotylized arm. The 10th and/or 11th suckers on arms I, II and IV in mature males are enlarged. The mature females produce large eggs. Fragments 658 base pairs in length were obtained from the mitochondrial cytochrome c oxidase subunit I (COI) gene of six specimens of Cistopus chinensis sp. nov. Estimated base frequencies were A = 0.3050, C = 0.1991, G = 0.1418 and T = 0.3541. A + T content was 65.91%. There were two haplotypes that differed by a single nucleotide transition at site 305(A→G). The genetic distance ranged from 0.000 to 0.002 among the individuals of the new species. The closest taxon with respect to genetic distance was C. indicus (0.118–0.121), and the most distant in the genus was C. taiwanicus (0.124–0.126). High bootstrap supported the monophyly of the Cistopus well (bootstrap maximum likelihood 91%, neighbour joining 89%, maximum parsimony 83%).
