Alpheus cf. armillatus H. Milne Edwards, 1837

Material examined (N=39). 4f, 25/IV/2004, St. 0 8 ( MZUESC #657); 1m, 2f, 29/IX/2004, St. 0 8 ( MZUESC #658); 3f, 31/X/2004, St. 0 8 ( MZUESC #736); 2f, 24/III/2005, St. 0 2 ( MZUESC #737).

Distribution. Western Atlantic – Bermuda and North Carolina to Brazil (from Ceará to Santa Catarina, Fernando de Noronha) ( Christoffersen 1998).

Ecological notes. Under rocks, in oyster banks, and in crevices of coral rocks; also common on seagrass flats. From shallow waters to about 9 m ( Chace 1972).

Previous records in Bahia. Smith (1869) (as A. heterochaelis Say, 1818 ), Gomes Corrêa (1972), Almeida et al. (2006).

Remarks. Gomes Corrêa (1972) in her list on decapods of the Abrolhos Archipelago listed A. armillatus and A. heterochaelis . However, the record of A. heterochaelis from this archipelago was based on Smith (1869) and should be therefore attributed to A. armillatus ( Christoffersen 1984) .

Alpheus armillatus is a species complex that includes at least seven species in the western Atlantic (A. Anker, personal communication; see also Mathews 2006). The identity of the Brazilian material, including the actual number of species present on the Brazilian coast, remains unknown.
