Dorsal fin XII, 14, membrane attached to caudal fin, with deep notch above last spine, first spine slightly higher than second; anal fin II, 15; pectoral rays 15; pelvic fin I, 4; caudal fin procurrent rays 10-14. Vertebrae 10 + 20. LL, without scales but with scalelike flaps; LL tubes 1-11, canal ends below 7th dorsal ray and caudal-fin base. Lower lip smooth mesially, plicate laterally. Upper lip crenulae 37-51. Gill rakers 23-29. Cephalic pore system complex; midsnout pores present.
