This study is the first inventory of ascidians from shallow waters (0-25 m) of coastal and reef habitats in the southern Gulf of Mexico where ascidian diversity is poorly known. Sampled environments in 14 locations (38 sites) with 134 samples collected from 2015 to 2017 included coral reefs, coastal lagoons, mangroves, seagrass, ports, and artificial platforms. The 31 identified species comprise 19 genera and 13 families. Ten species are newly reported in the Gulf of Mexico: Bonnet & Rocha, 2011; (Traustedt, 1882); Hartmeyer, 1912; Eudistomaaff.amanitum Paiva & Rocha, 2018; Millar, 1977; Monniot, 1983; Euherdmaniaaff.vitrea Millar, 1961; (Sluiter, 1885); (Hartmeyer, 1912) and Tokioka, 1954. Two new species will be described separately ( sp. and sp.). This study provides the first records for 26 species ascidians for the region as well as describes increased distributions of ten Atlantic species. Thus, our data provide a starting point for future ecological, experimental and taxonomic studies of ascidians of the Gulf of Mexico.
本研究首次对墨西哥湾南部沿海和珊瑚礁栖息地浅水区（0 - 25米）的海鞘进行了清查，该区域海鞘多样性鲜为人知。2015年至2017年期间，在14个地点（38个采样点）采集了134个样本，采样环境包括珊瑚礁、沿海泻湖、红树林、海草床、港口和人工平台。已鉴定的31个物种包括19个属和13个科。有10个物种是墨西哥湾新记录物种：博内特和罗查，2011年；（特劳施泰特，1882年）；哈特迈尔，1912年；Eudistoma aff. amanitum 派瓦和罗查，2018年；米勒，1977年；莫尼奥，1983年；Euherdmania aff. vitrea 米勒，1961年；（斯卢伊特，1885年）；（哈特迈尔，1912年）和户木冈，1954年。两个新物种将另行描述（物种1和物种2）。本研究提供了该区域26种海鞘的首次记录，并描述了10种大西洋物种分布范围的扩大。因此，我们的数据为未来对墨西哥湾海鞘的生态、实验和分类研究提供了一个起点。
