Material examined. Panama [Pacific]: 1 female, holotype, cl 10.8 mm, cw 12.5 mm ( MZUSP 33807 ), Las Perlas Is., small rocky islet off north-eastern coast of Isla Saboga , 8°38’39.5”N, 79°03’43.5”W, rock-sand bottom, 0–1.5 m at low tide, strong current, under rocks and in dead corals, leg.

Kaji, 22.04.2015 ; 1 ovigerous female, paratype, cl 8.5, cw 9.9 ( MZUSP 33686 ), Río Mar , 8°27’19.2”N, 79°58’09.4”W, rocky intertidal, low tide, under rocks and in rock crevices, leg. A. Anker, J.F.

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 ).
