Size of largest male: cl 4.7 mm ( MZUSP 33249); largest female: cl 5.1 mm ( MZUSP 30041). Numerous additional specimens (not listed above) are deposited in MZUSP.

Additional (extra-limital) material examined. Brazil: 1 male, 5 (3 ovig.) females, MZUSP 25346, Rio de Janeiro, Bacia de Campos, Petrobras oil platform P-65, depth: 16 m, fouling growth on platform piling, coll. J.B. Mendonça, 30.iii.2010 [material also examined by Cunha et al. (2015)].

Description. See Armstrong (1940) for original description (diagnosis), and Hendrix (1971), Ray (1974), Abele & Kim (1986) and Cunha et al. (2015) for illustrations; Santos et al. (2012) and Soledade & Almeida (2013) provided colour photographs of the Brazilian material of A. peasei (see also Figs. 7 View FIGURE 7 , 8 View FIGURE 8 ).

Distribution. Western Atlantic: Gulf of Mexico; Florida; throughout Caribbean Sea; Bermuda; Brazil: Bahia, Rio de Janeiro, Trindade and Martin Vaz Archipelago (Soledade & Almeida 2013 and references therein; Cunha et al. 2015; present study).

Ecology. Coral and rocky reefs and associated habitats rich in coral rubble, coralline algae and sponges; dwelling deep in crevices of coral rocks, among sponge and fouling growth, clumps of coralline algae etc.; intertidal to at least 30 m.

Remarks. Alpheus peasei is one of the most common crevice-dwelling snapping shrimps in the tropical western Atlantic, particularly in the Caribbean Sea. The species was previously known from Brazil based on records from Bahia and Campos Basin off Rio de Janeiro ( Santos et al. 2012; Cunha et al. 2015) and is now recorded for the first time from Trindade Island, where it appears to be fairly common. Alpheus peasei appears to be somewhat variable in the general colour of the body, ranging from greenish-yellow to reddish; however, the brown and white markings on the major chela are very diagnostic ( Figs. 7 View FIGURE 7 , 8 View FIGURE 8 ).
