|Abstract:||A second species of Grammatonotus from the Hawaiian Islands, tentatively
identified as G. macrophthalmus Katayama, Yamamoto & Yamakawa
(Callanthiidae), is recorded from French Frigate Shoals and the Northampton
Seamount based on observations from a research submersible. In the absence of
collected specimens, identification was made by comparing characters visible in
video images with previously published images and descriptions. The fish were
observed from 340 to 440 m at or near rocky habitats with crevices. All of the
observations were near current-swept areas that supported gold coral (Gerardia
sp.) colonies, although the fish were never seen within the colonies. A habitat
feature important for both Grammatonotus and Gerardia, such as current or
planktonic food supply, may therefore influence distribution of the fish. Extensive
fish surveys conducted in comparable depths at other areas of the archipelago
have not encountered this species, with one poorly documented exception
from trawling surveys. Two other range extensions of Grammatonotus are included
herein: Grammatonotus laysanus Gilbert from the Line Islands with a
specimen collected at Christmas Island at 274 m and an unidentified Grammatonotus
juvenile from the Tuamotu Archipelago at 705 m. Our examination of
specimens and review of previous records of Grammatonotus indicate that this
genus needs taxonomic revision.
