Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 9.0 cm SL Männchen/unbestimmt; (Ref. 2847)
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 12 - 18; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 16 - 27. Body moderately deep, belly sharply keeled, with 9 to 12 + 7 to 9 scutes. Snout blunt, pre-maxillae short and toothless, but prominent teeth in lower jaw; second supra-maxilla short, a little over half length of maxilla blade.
