Remarks.

Specimens of Pyropelta corymba are herein confirmed from the hydrocarbon seep sites “ Jaco Scar ” (9.12, - 84.84), “ Mound 12 ” (8.93, - 84.31), and “ The Thumb ” (9.05, - 84.39) from the Pacific Costa Rica Margin. This species was sampled from mussels, tubeworms, rocks, and wood between 995–1,887 m depth. This extends the known range of this species southward from the Californian coast and Gulf of California.
