  • Diagnosis. Pectoral fin absent; dorsal-fin origin slightly in front of gill opening; trunk very short; lower jaw short, not covering intermaxillary teeth or first vomerine tooth when closed. Lateral-line pores: predorsal 3, preanal 9, and total 23–32. Vertebrae: predorsal 8, preanal 15–16, total 131+–136. Dentition: 2 compound intermaxillary teeth; 3–5 compound teeth on vomer; single row of compound teeth on lower jaw; maxillary teeth in 2‒3 irregular rows. Body uniformly tannish to brownish, lower part of posterior parts of anal-fin and lower part of caudal fin darker.
