Alpheus cf. packardii Kingsley, 1880

(Figure 7B)

Material examined. Petro-UFS—2 OF; size range: 5.05 ≤ CL ≤ 6.22 mm; average: CL = 5.64 ± 0.83 mm; CZUFS CRU- 00026.

Stations. Petro-UFS—5.

Distribution. Western Atlantic—Bermuda, Virgin to South Carolina, Florida, Gulf of Mexico, Bahamas, Mexico (Quintana Roo and Yucatan), West Indies, Venezuela, and Brazil (Atol das Rocas, Fernando de Noronha, Trindade and Martin Vaz, from Amapá to São Paulo) ( Christoffersen 1979, 1998; Rodríguez, 1980; Martínez-Iglesias et al. 1996) as Alpheus normanni (Kingsley) ( Santos et al. 2012; Almeida et al. 2012, 2018; Anker et al. 2016).

Ecological notes. From intertidal to a depth of 70 m. On coral reefs, sand, mud, broken shells, algae, and sponges. On crevices of coral rubble and Halimeda sp. clumps. Reported in crevices of coral rubble from southern Bahia ( Christoffersen 1979; Róman-Contreras & Martínez-Mayén 2010; Almeida et al. 2012; Santos et al. 2012).

Remarks. Previously recorded as Alpheus normanni (Kingsley) . Later A. packardii was considered a junior synonym of A. normanni ( Chace 1937, 1972; Christoffersen 1979). Kim & Abele (1988) removed A. packardii from the synonymy of A. normanni . However, the taxonomy of A. normanni and A. packardii remains unsettled due to the presence of cryptic taxa on both sides of the Americas, and, the true identity of the material from Brazil remains unknown ( Williams et al. 2001; Almeida et al. 2012; Soledade & Almeida 2013), requiring a taxonomic revision. Because of that the specie is reported as A. cf. packardii for Brazilian waters. Found in the present study associated with algae banks.

Previous records in Sergipe. None.
