New records and range extensions of Astrodictyum panamense (Ophiuroidea: Gorgonocephalidae) in the eastern Pacific Ocean

Abstract

The ringed basket star Astrodictyum panamense is an ophiuroid resident of coral and rocky reefs from the central and southern Gulf of California and oceanic islands from the eastern Pacific. This paper presents new records of this species obtained from field work and internet sources, and includes its northernmost and westernmost occurrence in the Eastern Pacific (Adair Bay, Gulf of California, and Tortugas Bay, on the Pacific side of Baja California, respectively), as well as Roca Partida Island, in the Revillagigedo Archipelago.
