The genus Baba, 1932 (Gastropoda, Nudibranchia, Dendronotidae), which was previously thought to be monotypic and restricted to the Western Pacific, is here expanded with the description of a second species, , discovered in the Yellow Sea, China. The new species is similar in general body shape to its sole congener, Baba, 1932, but these species can be distinguished based on both external morphology and internal anatomy. Phylogenetic analyses reconstructed by Bayesian inference and maximum-likelihood methods using concatenated mitochondrial (COI, 16S rRNA) and nuclear (H3) genes and species delimitation analyses support the monophyly of as well as the separation of the two known species.
巴巴属（Baba，1932年）（腹足纲，裸鳃目，枝背海蛞蝓科），此前被认为是单型的且仅限于西太平洋地区，在此通过对在中国黄海发现的第二个物种——[此处原文缺失物种名]的描述进行了扩充。新物种在总体体型上与其唯一的同属物种——巴巴（Baba，1932年）相似，但这些物种可以根据外部形态和内部解剖结构加以区分。使用串联线粒体（COI、16S rRNA）和核基因（H3）通过贝叶斯推断和最大似然法重建的系统发育分析以及物种界定分析支持了[此处原文缺失属名]的单系性以及两个已知物种的分离。
