Remarks. Previous records on the coast of São Paulo state include Santos ( Rathbun 1918) and Ubatuba ( Negreiros-Fransozo et al. 2002). This species was once considered to have a transisthmian distribution, recorded for eastern Pacific, from Nicaragua to Peru ( Rathbun 1918; Chace & Hobbs 1969; Melo 1996), but the specimens from the eastern Pacific were assigned to a new species ( Aratus pacificus Thiercelin & Schubart, 2014 ), sisterspecies of A. pisonii ( Thiercelin & Schubart 2014) . Sequences accession number (GenBank): CCDB 1857—16S ( KU313107 ), COI ( KU313075 ) ( Mantelatto et al. 2018a).
