( Fig. 8J )

Material examined. Brazil, São Paulo: 1 ♀, CCDB 6707 , Ubatuba, Itaguá , Porto de Itaguá , colls. R. Santos & I. Moraes, i.2019 ; 1 ♂, CCDB 6713 , Cananéia, Ilha da Figueira , colls. R. Santos & I. Moraes, 27.xi.2020 .

Distribution. Western Atlantic— USA (Florida), Mexico (Yucatan Peninsula), Cuba, and Brazil (Pernambuco, Rio de Janeiro, São Paulo) ( Chace 1972; Abele & Kim 1986; Camp et al. 1998; Coelho et al. 2006; Duris et al. 2009; Vieira et al. 2012; Pachelle et al. 2015; Moraes et al. 2020b).

Remarks. Previous records from the coast of São Paulo include Ubatuba, in Pier do Porto in Itaguá ( Moraes et al. 2020b). It is found in shallow waters associated with sponges ( Chace 1972; Ramos-Porto & Coelho 1998; Vieira et al. 2012; Pachelle et al. 2015; Moraes et al. 2020b). In general, shrimps of the genus dwell deep in sponge canals ( Duris et al. 2011; Anker et al. 2021). Probably due to these, its small size (carapace length: 1.53–2.71 mm) and the relationship among the shrimp’s color and the sponge host ( Moraes et al. 2020b), it is hard to sample. There is available material from São Paulo coast in other collections such as MZUSP 40095 and 40096, and it is deposited in the Biological Collection from São Paulo State University—Zoology Department, Botucatu-SP ( Moraes et al. 2020a). Sequences accession number (GenBank): CCDB 6713—16S ( OM720040 ), COI ( OM672405 ) (present study).
