ineligible as a standard Japanese name. Therefore, we herein propose a new standard Japanese name, “Uguma-unagi” for this species based on the specimens (KYUM-PI-05434). The proposed species name is based on the body color of adult of this species [see photo in Wanatabe et al. (2009)] and is a combination of “uguma” meaning “sesame” in the Okinawan dialect to express the irregular mottled coloration pattern on the body of the species, and “unagi” meaning “eel” in Japanese.
