Diagnosis. This new species belongs to the small, brown unpatterned group of moray eels, with the following combination of characters: dorsal-fin origin before gill opening, jaw pores with brown rim, two branchial pores, total vertebrae 134 (MVF: 9-59-134), three median intermaxillary teeth, uniserial maxillary and vomerine teeth.

Description. A medium-sized moray with moderately elongate body, depth at gill opening 19.05 and at anus 24.9 in TL. Anus located slightly before mid-body, preanal length 2.05 in TL. Head 6.89 in TL; snout short and blunt, its length 6.52 in HL; jaws subequal, upper jaw 2.9 in HL. Eye large, almost midway between rictus and the snout tip, eye diameter 20.21 in HL; interorbital space 8.7 in HL ( Table 1). Anterior nostril in a moderate tube, posterior nostril above anterior margin of eye. Branchial pores 2, located above and before gill opening. Dorsal-fin origin closer to gill opening than to rictus but before gill opening and just above 1st branchial pore. Gill opening at mid-side in a small diagonal slit. Teeth smooth, uniserial; outer intermaxillary teeth 18 (9 on each side), teeth 4 and 8 are smaller than others; median intermaxillary teeth 3, strong, curved, last two close together; maxillary teeth uniserial, 17 on each side, teeth 3 and 5 are smaller than others; vomerine teeth uniserial, 8; lower jaw with outer row of 24 teeth on each side and 1 inner tooth on each side near anterior end ( Fig. 2 ).
