Diagnosis: head length 14.2-14.9% SL (mean 14.6%), decreasing with size (Ref. 81678). Origin of first dorsal spine situated behind posterior edge of pectoral fin, 2.5-9.9% SL (mean 5.3%)(Ref. 52436, 81678). Body depth 6.7% SL; distance from tip of snout to last externally visible dorsal spine 50.5-51.6% SL (mean 51.2%), decreasing with size (Ref. 81678). Origin of soft dorsal fin clearly anterior to origin of soft anal fin (Ref. 52436, 81678). Lower jaw length 21.3-26.9% HL (mean 23.9%), increasing with size; distance from gill opening to dorsal pectoral fin base 4.3-9.6% HL (Ref. 81678). 24+1 to 26+1 (median 25+1) dorsal spines; no preorbital spines; no preopercular spines (Ref. 52436, 81678). Color pattern characterized by a series of mediodorsally situated dark brown to black spots on body, tail and proximal parts of dorsal and anal fins (Ref. 52436).
Body shape (shape guide): eel-like.
