Biemna Gray, 1867 is characterized by stylote or exceptionally oxeote megascleres arranged in a plumoreticulate skeleton, ectosomal skeleton consists of the brushed endings of choanosomal tracts, microscleres are sigmas, microxeas, commata and raphides (Hajdu Van Soest 2002). Currently, Biemna has 55 valid species (Van Soest et al. 2018). In Brazil, three species are known from northern region (Muricy 2018): Biemna microacanthosigma Mothes, Hajdu, Lerner Van Soest, 2004, Biemna spinomicroxea Mothes, Campos, Lerner, Carraro Van Soest, 2005, Biemna trisigmata Mothes Campos, 2004. In this present study, a new name is proposed for a preoccupied combination, Biemna thomasi nom. nov. The species Biemna caribea Pulitzer-Finali, 1986 is recorded and described for the first time in Brazilian waters. Six specimens of Biemna were studied in Pernambuco and Bahia States. All specimens were preserved in 80% ethanol and deposited on the Porifera Collections at the Universidade Federal de Pernambuco (UFPEPOR).
