Synalpheus cf. brevicarpus ( Herrick, 1891)

(Figure 7C)

Material examined. Penaeid—56 (25 M, 17 F, 14 OF); size range: 1.84 ≤ CL ≤ 3.25 mm; average: CL = 2.59 ± 0.36 mm; CZUFS CRU- 00345.

Stations. Penaeid—3, 6, and 9.

Distribution. Western Atlantic—Florida, Bermuda, Bahamas, West Indies, Panama, and Brazil (from Ceará to Rio Grande do Sul) ( Christoffersen 1979, 1998; Bezerra & Coelho 2006; Almeida et al. 2012, 2018). The Eastern Pacific records correspond to Synalpheus digueti Coutière (which also corresponds to multiple species) ( Almeida et al. 2012; Santos et al. 2012).

Ecological notes. Commensal of sponges of the genus Ircinia Nardo ( Bezerra & Coelho 2006) . On sandstone reefs, rocks covered by Hydrozoa, and on algae ( Almeida et al. 2012).

Remarks. Found in the present study associated with a bryozoan ( Reteporella sp., Phidolopodidae). Synalpheus brevicarpus belongs to a species complex, which also includes S. brevicarpus sensu (Herrick) , S. brevicarpus guerini Coutière , and S. digueti Coutière ( Almeida et al. 2012; Santos et al. 2012). Since this complex requires a taxonomic revision, the species is mentioned as S. cf. bravicarpus.

Previous records in Sergipe. None.
