Alpheus lacertosus belongs to the Edwardsii species group within the genus Alpheus (Kim and Abele 1988). The species name refers to the Latin "lacertosus" (musclular), and refers to relatively large major chela of the species compared to similar species. Type locality: South of Valparaiso, Chile (Kim and Abele 1988), types stored at the National Museum of Natural History, Smithsonian Institution (USNM). Holotype: USNM 229923 . Common name: Southern speckled-claw snapping shrimp.
Free-living in the rocky intertidal and shallow subtidal, found under large rocks, clumps of algae, and among barnacles, ascidians, and shells (Kim and Abele 1988, Knowlton et al. 2008).
Maximum body size (carapace length, or CL) of males is 15.6 mm (Kim and Abele 1988). Alpheus lacertosus can be disinguished from closely related species A. californiensis by the wider rostral carina and by the relatively larger size of A. lacertosus (Kim and Abele 1988, Knowlton et al. 2008)
