Distinguished from all other Micronesian genera by having a nearly continuous bony ridge extending from the anterior margin of the lower eye to the posterior margin of the upper eye, and a narrow interorbital space, always greater than the greatest eye diameter.

Description: Characterized further by blotchy pale brown body color with three rows (approximately along lateral line) of large black-edged pale spots enclosing black dots, except posterior most spot on lateral line sometimes solid black; first dorsal ray moderately prolonged and separated from rest of fin, with central stalk and narrow, fringed membrane, extending more than half-way to base; ctenoid scales on eyed side, cycloid on blind side; palmate gill rakers; lower eye slightly anterior to upper; lower jaw extending to below front edge of lower eye or slightly posterior; uniserial teeth on both jaws; depth of body 2.0-2.4 in SL (Ref. 90102).
