The basket star Gorgonocephalus eucnemis is a common ophiuroid resident of rocky bottoms and artificial substrata at depths of 8 to 1,850 m, and in the eastern Pacific is distributed from the Bering Sea to San Diego, USA. This paper presents a new record of this species obtained with a submersible at Guadalupe Island, Mexico (29.10976°N, −118.25417°W), which extends its distribution range over 400 km, and corresponds to the southernmost site of occurrence of this ophiuroid in the eastern Pacific.
