Description. See Kingsley (1880) for original description (with single diagrammatic figure published in Kingsley 1883); Zimmer (1913) provided a more detailed diagnosis with illustrations; Santos et al. (2012) and Soledade & Almeida (2013) published colour photographs of the Brazilian material (identified as A. cf. packardii  ) (see also Fig. 6View FIGURE 6).

Distribution. Western Atlantic (species complex, see below): North Carolina to Florida; Gulf of Mexico; throughout Caribbean Sea; Bermuda; Brazil: Amapá to Espírito Santo, Fernando de Noronha, Atol das Rocas  , Trindade Island ( Chace 1972; Christoffersen 1979; Soledade & Almeida 2013 and references therein; present study).

Ecology. Various hard and soft bottom habitats, e.g., rocky and mixed rock-sand shores, coral reefs and associated rubble flats, seagrass beds and coralline algae; typically under rocks, among seagrass roots, in crevices of coral rubble etc.; intertidal to at least 80 m (species complex, see below).

Remarks. Alpheus packardii  and A. normanni Kingsley, 1878  are part of the transisthmian A. normanni  A. packardii  species complex, which is currently being revised (Anker & Santos, in study). The taxonomic identity of the western Atlantic material identified as A. normanni  , A. packardii  , A. bermudensis Spence Bate, 1888  , A. beanii Verrill, 1922  , and A. longichaelis Carvacho, 1979  will need to be carefully re-assessed. The Brazilian material was variously identified as A. normanni  , A. packardii  or A. beanii  (see Soledade & Almeida 2013 for details) and it is quite possible that it refers to more than one species. The species recorded from Trindade Island appears to be morphologically close to A. beanii  , which was treated as a junior synonym of A. normanni  by Christoffersen (1979) and is now in the synonymy of A. packardii ( De Grave & Fransen 2011)  .
