The San Matías gulf is a marine biodiversity hotspot located in the Argentinean Patagonia. Although there are several studies on gastropod mollusks from Argentina, nudibranchs remain less studied. In this faunistic assessment 15 species of nudibranchs were found in San Matías gulf, including two new family records for Argentina: Coryphellidae and Dotidae. Although Magellanic nudibranchs are clearly predominant in this area, warm water species such as Doto uva and Coryphella cf. verta are recorded and the known geographic range of five species is extended. In addition, Rostanga pulchra and Diaulula hispida extend their range to the north of the Argentine Patagonia.
圣马蒂亚斯湾是位于阿根廷巴塔哥尼亚的一个海洋生物多样性热点地区。尽管有几项关于阿根廷腹足纲软体动物的研究，但裸鳃亚目动物的研究仍然较少。在这次动物区系评估中，在圣马蒂亚斯湾发现了15种裸鳃亚目动物，包括阿根廷的两个新科记录：科里鳃科和多蒂科。尽管麦哲伦裸鳃亚目动物在该地区显然占主导地位，但仍记录到了诸如葡萄多德海蛞蝓和近似绿背科里鳃海蛞蝓等暖水物种，并且有5个物种的已知地理分布范围得到了扩展。此外，美丽玫瑰海牛和希氏双鳃海牛的分布范围扩展到了阿根廷巴塔哥尼亚北部。
