Head of moderate to large size (27-30% SL); eyes of moderate size (8-10% SL); mouth of moderate size (upper jaw length 10-12% SL), reaching below middle to end of pupils; 19-22 circumorbital head pores arranged uniserially (sometimes biserial above eyes); each orbital tentacle broad and crenulate with short, broad lobes (2-3% SL); nasal tentacles elongate with two or three very short lobes on each side; gill rakers simple.  
Body scales cycloid, lateral-line scales end under posterior dorsal spines, anterior scales overlapping, each with single dorsal pore positioned posteriorly, posterior scales not overlapping, each with median pore at either end.  
Two dorsal fins, first dorsal slightly elevated (second spine 8-12% SL) originating midway between eyes and posterior preopercular margins, last spine connected to base of second dorsal fin; flaps extending posteriorly from dorsal spines bound in fin membrane; last dorsal spine connected by membrane to caudal fin; anal fin membrane deeply incised, last ray narrowly connected to caudal peduncle; caudal fin rounded (19-21% SL).
