An integrative molecular and morphological study is presented for the family Unidentiidae. Molecular phylogenetic analyses were conducted with the inclusion of all previous and newly obtained molecular data for the family Unidentiidae Millen Hermosillo 2012. A new species of the genus Unidentia Millen Hermosillo 2012, U. aliciae sp. nov., is described from Thailand as part of an inventory of sea slugs at Koh Tao. All up-to-date available morphological data for the species of the genus Unidentia is for the first time summarized. Morphological differences among the different species of Unidentia are clarified showing that every species has its own distinguishable morphological traits. According to the new molecular and morphological data, the family Unidentiidae is re-confirmed as a well-supported taxon of the aeolidacean nudibranchs. The taxonomy and phylogeny of the Aeolidacea in the light of the family Unidentiidae is briefly discussed and necessity of a fine-scale and narrowly-defined taxa approach instead of a ''superlumping'' one is highlighted.
本文呈现了对无齿海蛞蝓科的一项综合分子与形态学研究。纳入了无齿海蛞蝓科（Millen Hermosillo，2012）所有先前及新获得的分子数据，进行了分子系统发育分析。描述了来自泰国涛岛的一种新的无齿海蛞蝓属（Unidentia Millen Hermosillo，2012）物种，即艾丽西亚无齿海蛞蝓（U. aliciae sp. nov.），这是对海蛞蝓清查工作的一部分。首次总结了无齿海蛞蝓属物种所有最新可得的形态学数据。明确了不同无齿海蛞蝓物种之间的形态差异，表明每个物种都有其独特的形态特征。根据新的分子和形态学数据，再次确认无齿海蛞蝓科是裸鳃亚目海蛞蝓中有充分支持的一个分类单元。简要讨论了基于无齿海蛞蝓科的裸鳃亚目分类学和系统发育，并强调了采用精细尺度和狭义定义分类单元方法而非“过度合并”方法的必要性。
