Distinguishing characteristics of metamorphosed female: relatively small esca, width about equal to length; low rounded terminal escal papilla; well developed anterior and posterior escal appendages, usually bearing small secondary filaments; bulbous anterior escal appendage, sometimes branched; laterally compressed posterior escal appendage, row of small secondary filaments along outer margin, at most 5; posterobasal margin of terminal papilla with escal pore; lower jaw with 14-65 teeth, upper jaw with 18-99 teeth; vomerine teeth 4-9 (Ref. 86949).
