摘要

A new porcellanid crab, Petrolisthes landsendi GARASSINO NYBORG n. sp., from the Upper Cretaceous (upper Santonian) Nanaimo Group of Vancouver Island (British Columbia, Canada) is herein described. Petrolisthes landsendi GARASSINO NYBORG n. sp. represents the oldest species of Petrolisthes STIMPSON, 1858 and is the first species from the northeastern Pacific, thus expanding the stratigraphical age and geographical range of the genus.
