The Entomolepididae family is a small taxon with a very characteristic body morphology and is represented, in the Atlantic Ocean, by three genera and five species. A recent study in Todos-os-Santos Bay, in Bahia State, has revealed a new species of Spongiopsyllus and a new species and genus belonging to the Entomolepididae. The new species of Spongiopsyllus is found in association with the sponge Aplysina cauliformis (Carter, 1882) sampled at the Porto da Barra beach. It is distinguished from its congeners mainly by differences in the segmentation pattern of the antennule, endopod of antenna, and the setation of the maxillule, maxilla and maxilliped. The new genus and species from Parmulodinae Eiselt, 1959 is found in association with the sponge Aplysina solangeae Pinheiro, Hajdu & Custodio, 2007, sampled at the Yacht Club Beach. The genus differs from others Parmulodinae mainly due to segmentation pattern of the antennule, endopod of antenna, maxilliped and swimming legs. Among the siphonostomatoid families that live in association with invertebrates, the Entomolepididae, Brady 1899 is a small taxon with very characteristic body morphology. The flattened oval aspect and the body shield covering almost the entire body distinguishes the group from all other families and suggests a life mode attached to its host. The Entomolepididae comprises 17 species classified in seven different genera (Ahyong et al. 2011; Canario et al. 2012; Lee & Kim 2017; Uyeno & Jonhsson 2018; Canario et al. 2019) being recorded in all oceans of the world. According to Boxshall & Halsey (2004), the main host group for the Entomolepididae is Porifera. Considering the
