Abstract 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.

Introduction Smittinidae Levinsen, 1909 is among the most diverse families of marine bryozoans, comprising about 400 species distributed worldwide. This family includes 20 extant genera, of which the species Parasmittina Osburn, 1952, Smittina

Norman, 1903, and Smittoidea Osburn, 1952 contain about two thirds of the species described (Bock and Gordon 2020). In Brazil, the Smittinidae is the fourth largest family of cheilostome bryozoans, represented by five genera— Parasmittina, Hemismittoidea Soule & Soule, 1973, Pleurocodonellina Soule & Soule, 1973, Smittina, and Smittoidea (Vieira et al. 2020). Most of the species recorded so far belong to Parasmittina, including some species descri
