Here, we present the taxonomy of five little-known cheilostome smittinid species of Bahia State, northeast Brazil, assigned to Hemismittoidea Soule & Soule, 1973, Smittina Norman, 1903, and Smittoidea Osburn, 1952. Specimens of four species previously reported in the studied area were reassessed: Hemismittoidea asymmetrica Ramalho et al., 2018, Smittina affinis (Hincks, 1862), Smittoidea evelinae (Marcus, 1937), and Smittoidea reticulata (MacGillivray, 1842). Hemismittoidea asymmetrica here is considered a junior synonym of Hemismittoidea corallinea Soule & Soule, 1973. The last three species here are assigned to Smittina smittiella Osburn, 1947, Smittoidea numma (Marcus, 1949) comb. nov., and Smittoidea complexa sp. nov., respectively. An additional species, Smittoidea pacifica Soule & Soule, 1973, is recorded for the first time in Brazil. Diagnostic characters of Smittinidae genera and species are discussed, and new combinations are proposed. Most of the taxa reported here were collected from natural substrata, mainly from coral reefs and rhodoliths, and also from artificial structures such as experimental plates, which can provide evidence regarding the passive dispersal ability of these animals (e.g., as hull fouling) and their potential for bioinvasion along the Brazilian coast.

在巴西东北部的巴伊亚州的一些Smittinidae（Bryozoa，Cheilostomata）上，描述了一个新物种

在这里，我们介绍巴西东北部的巴伊亚州的5种鲜为人知的螯龟科的分类学，分别归类于1973年的Hemismittoidea Soule＆Soule ，1903年的Smittina Norman和1952年的Smittoidea Osburn。以前研究中曾报道过的4种物种的标本重新评估了该区域：不对称半翅目Hemalmittoidea Ramalho等人，2018年，Smittina affinis（Hincks，1862年），Smittoidea evelinae（Marcus，1937年）和Smittoidea reticulata（MacGillivray，1842年）。Hemismittoidea asymmetrica在这里被认为是Hemismittoidea Corallinea的初级同义词Soule＆Soule，1973年。这里的最后三个物种分别是Smittina smittiella Osburn，1947年，Smittoidea numma（Marcus，1949年）。十一月，和Smittoidea complexa sp。分别。另一种，Smittoidea pacificaSoule＆Soule，1973年，在巴西首次录制。讨论了Smittinidae属和种的诊断特征，并提出了新的组合。此处报告的大多数分类单元均来自自然地层，主要来自珊瑚礁和杜鹃花，以及人工结构（例如实验板），它们可以提供有关这些动物的被动扩散能力（例如，船体结垢）及其动物的证据。巴西沿海生物入侵的潜力。
