Chaceon ramosae Manning, Tavares & Albuquerque, 1989: 646, figs. 2–3.

Material examined. Brazil, São Paulo: 1 ♀, CCDB 6166, Ubatuba, coll. D. Rosa, 12.ii.2017 .

Distribution. Western Atlantic—Brazil (Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul), mostly between 19°S and 30°S (Manning et al. 1989; Melo 1996; Pezzuto et al. 2006; Alvarez Perez et al. 2009; Mantelatto et al. 2014a).

Remarks. Previous records in São Paulo include the following offshore localities, 23º51’39’’S / 42º55’18’’W– 24º22’45’’S / 43º33’54’’W (Mantelatto et al. 2014a), and Ubatuba (present study). The molecular phylogeny of this species revealed low genetic variability in South Atlantic populations, so no doubt is raised about its taxonomic status (Mantelatto et al. 2014). Sequences accession number (GenBank): CCDB 4701—16S (KC676752), COI (KC676775) (Mantelatto et al. 2014a).
