Description. Morphometric data for the four type specimens are summarized in Table 1. Body elongate, slightly compressed, more so toward caudal-fin base, with greatest body depth immediately anterior to dorsal-fin origin, and least caudal-peduncle depth closer to caudal-fin base than to posterior end of anal-fin base. Dorsal head profile slightly convex; ventral head profile straight. Dorsal body profile slightly convex anterior to dorsal-fin origin; straight or slightly convex from dorsal-fin origin to origin of dorsal procurrent caudal-fin rays. Ventral profile of body rounded anterior to anal-fin origin; somewhat concave from anal-fin origin to origin of ventral procurrent caudal-fin rays.
