Anker , J.F. Lazarus-Agudelo & T. Kaji , 20.03.2015 . Previous records from Panama . Ferreira et al. (2020) . Distribution . East Pacific: Panama (Río Mar, Las Perlas Is.) ( Ferreira et al. 2020 ). Ecology . Intertidal and shallow subtidal, known depth range: 0–1.5 m ; under large rocks on sand-rock bottoms ( Ferreira et al . 2020 ). Remarks . Petrolisthes lazarus is a recently described species, presently known only from two localities on the Pacific coast of Panama ( Ferreira et al. 2020 ). It seems to be most closely related to P. crenulatus Lockington, 1878 , which is distributed further north in the tropical eastern Pacific, from the Gulf of California to Oaxaca , Mexico , but can be easily distinguished by the presence of a dense field of setae on the outer (lateral) surface of the P1 palm ( Fig. 60 ).
