Rayons mous dorsaux (Total) : 7 - 8; Rayons mous anaux: 9 - 10; Vertèbres: 31 - 32. Distinguished from all other species of the genus Phalloceros, except
Phalloceros leticiae and Phalloceros mikrommatos by the roundish to rounded and well-defined ocellated lateral spot. Differs from Phalloceros leticiae by the postorbital length in females 24.8-39.3 % SL (vs. 39.2-42.2 % SL) and in males 29.3-38.2 %
SL (vs. 36.7-42.3 % SL); and from Phalloceros mikrommatos by the number of
anal-fin rays in females 10 (vs. 11) (Ref. 76852).
