Can be further differentiated from its congeners, except Phalloceros mikrommatos and Phalloceros ocellatus, by the possession of a roundish to rounded and well-defined ocellated lateral spot (rarely absent). Differs from Phalloceros ocellatus by the postorbital length in females (39.2-42.2 % SL vs. 24.8-39.3 % SL, respectively) and in males (36.7-42.3 % SLvs. 29.3-38.2 % SL, respectively). Can be separated from Phalloceros mikrommatos by the number of anal fin rays in females (10 vs. 11, respectively) (Ref. 76852).Description: Pectoral fin with 6 branched rays; longitudinal series of scales 28; transverse series of scales 7 (Ref. 76852).
