In this study, we described a new species of octopus and named it based on nine specimens captured in the waters of southeast China. is a small to moderate-sized octopus. The most characteristic and defining morphological features are the reddish-orange to reddish-brown skin, gills with 8 or 9 lamellae per demibranch, \∧/-shaped funnel organ, and small suckers. Fragments obtained from the mitochondrial cytochrome c oxidase subunit I (COI) gene of nine specimens were 593 bp in length, and the genetic distance among the specimens of and the other 16 octopods ranged from 11.13 to 21.09%. Topologies resulting from ML and BI analyses of the COI gene showed a highly supported monophyletic clade (bootstrap value [BS] = 94%, posterior probability [PP] = 100%) containing all the specimens identified as
在本研究中，我们描述了一种新的章鱼物种，并根据在中国东南部海域捕获的9个标本对其进行了命名。[新物种名称]是一种小型到中型的章鱼。最具特征性和决定性的形态特征是红橙色至红棕色的皮肤、每半鳃有8或9个鳃片的鳃、∧/-形的漏斗器官以及小吸盘。从9个标本的线粒体细胞色素c氧化酶亚基I（COI）基因获得的片段长度为593 bp，[新物种名称]标本与其他16种章鱼之间的遗传距离在11.13%至21.09%之间。基于COI基因的最大似然法（ML）和贝叶斯推断（BI）分析所得到的系统发育树显示，一个包含所有被鉴定为[新物种名称]标本的单系分支得到了高度支持（自展值[BS]=94%，后验概率[PP]=100%）。
