Previous records. Ubatuba (Christoffersen 1979; Pires 1992; Chacur & Negreiros-Fransozo 1999; Costa et al. 2000; Fransozo et al. 2002; 2005; Negreiros-Fransozo et al. 2002; Braga et al. 2009; Baeza et al. 2010; Nunes et al. 2010; Mantelatto et al. 2016b); São Vicente estuary (Reigada et al. 2006); Santo Amaro Island (Municipality of Guarujá), Santos, Peruíbe, Cananéia and several stations sampled by the R/V Emília (Christoffersen 1979); locality not mentioned (Christoffersen 1982).

Remarks. Due to the fact that E. oplophoroides is mainly collected as by-catch in artisanal shrimp fishing, many studies have been carried out on this species along the São Paulo coast, such as population and reproductive aspects (Fransozo et al. 2005; Braga et al. 2009; Baeza et al. 2010; Nunes et al. 2010) and larval morphology (Negreiros- Fransozo et al. 2002). Sequences accession number (GenBank): CCDB 3769 - 16S (KU312980), COI (KU313009).
