Material examined . None. Previous records from Panama . Gore & Abele (1974 , 1976 ); Gore (1982) ; Abele & Kim (1989) . Distribution . East Pacific: Panama ( Panama Canal area, Ciudad de Panamá ) ( Gore 1982 ). Ecology . Largely intertidal; within or on the fringe of red mangrove swamps, apparently able to tolerate very low salinities ( Gore & Abele 1974 ). Remarks . Petrolisthes lindae is largely sympatric with the closely related P. armatus , P. nobilii Haig, 1960 (see below) and P. robsonae Glassell, 1945 (see below). However, P. lindae has just one tooth and a lobe on the P1 carpus ( vs. two or three teeth, as in the other species); the epibranchial tooth is either vestigial or absent ( vs. distinct in the other species); and the granulation of the carapace slightly from each of the other three species ( Gore & Abele 1974 , 1976 ). The closeness of P. lindae to these three species led Gore & Abele (1974 , 1976 ) question whether a hybridisation between two of the above species may have occurred in the past, resulting in P. lindae . Adults of P. lindae and P. robsonae , as well as juveniles of P. lindae , P. armatus and P. robsonae , are particularly difficult to tell apart ( Abele & Kim 1989 ).
