Marrus cf. orthocanna (Kramp, 1942)

Remarks: in Migotto et al. (2002) faunistic revision, the record for the species is a mistake as Alvariño (1981) did not record the species for Brazilian waters. Araujo (2012) reported the occurrence of a specimen that closely resembles this species at southeastern Brazil. However, the material observed, a single nectophore, was not well preserved. So, new material of this species, in better condition, needs to be examined to confirm the species occurrence in the area.

Distribution in South America: Atlantic Ocean, Brazil, at 23ºS 41ºW (Araujo et al. 2010; Araujo 2012). Habitat: neritic species (Araujo et al. 2010; Araujo 2012).
