Here, we review the taxonomy of the Apodida species from the Brazilian coast and oceanic islands. Eleven species are reported, four Chiridotidae (including Chantalia conandae gen. et sp. nov.) and seven Synaptidae (including Yemoja gen. nov.). Chantalia conandae gen. et sp. nov. is a shallow-water species diagnosed by having 12 tentacles, 4–6 Polian vesicles and vase-shaped ciliated funnels along the mesenteries, and by lacking a calcareous ring, sensory cups and ossicles. Based on the morphology of the calcareous ring (dumbbell-shaped plates) and of the tentacles (12, simple), we propose the new genus Yemoja gen. nov. to accommodate Leptosynapta brasiliensis (Yemoja brasiliensis comb. nov.). To date, there are no records of Myriotrochidae in Brazil. In addition to species descriptions and photographs, we provide novel data on the calcareous ring stereom and a discussion about the calcareous ring morphology in Apodida, an identification key for the Brazilian species, a synoptic table with morphological characteristics of the Brazilian genera, and a synoptic table comparing the ossicleless Apodida genera. Finally, we provide the geographic and bathymetric distribution of the Apodida species reported for the South Atlantic and adjacent Southern Ocean. Based on our compendium, the Synaptidae is most diverse in warmer waters, while the Myriotrochidae is most diverse in colder waters. Also, the Atlantic coasts of South America and Africa have a surprisingly low with their adjacent Antarctic waters. We expect that dedicated holothuroid research will greatly increase the diversity of Apodida throughout the South Atlantic Ocean, especially off the continental shelf.

在这里，我们回顾了来自巴西海岸和海洋岛屿的Apodida物种的分类。据报道有11个物种，其中有4种猫科（包括Chantalia conandae gen。et。nov。）和7种突触科（包括Yemoja gen.nov。）。Chantalia conandae根。等。十一月 是一种浅水物种，其诊断是沿肠系膜有12个触手，4–6个Polian囊泡和花瓶状纤毛漏斗，并且缺少钙质环，感觉杯和小骨。根据钙质环（哑铃形板）和触角（12个，简单）的形态，我们提出了新属叶莫哈属。十一月 容纳巴西扁豆（Yemoja brasiliensis梳。十一月）。迄今为止，巴西还没有Myriotrochidae的记录。除了物种描述和照片之外，我们还提供有关钙质环立体的新数据，以及有关Apodida中钙质环形态的讨论，巴西物种的识别码，具有巴西属形态特征的概要表和概要表比较无小骨的Apodida属。最后，我们提供了报告给南大西洋和邻近南大洋的Apodida物种的地理和测深分布。根据我们的纲要，突触科在较温暖的水中种类最丰富，而Myriotrochidae在较冷的水中种类最丰富。同样，南美和非洲的大西洋沿岸与邻近的南极水域相距甚低。
