Etymology: Phalloceros: Greek, phallos = penis + Greek, keras = horn (Ref. 45335); mikrommatos: From the Greek adjective 'mikrommatos', meaning small-eyed, in reference to the lateral spot, which is rounded and has an external light right.

Morphology | Morphometrics
soft rays: 9 - 11;
Vertebrae: 31 - 32. Diagnosed from other species of the genus Phalloceros by the first gonapophysis angled 5-15 degrees relative to vertebral column and second gonapophysis angled zero-15 degrees relative to vertebral column. Differs further from its congeners, except Phalloceros leticiae and Phalloceros ocellatus, by the roundish to round and well-defined ocellated lateral spot. Distinguished from Phalloceros leticiae and Phalloceros ocellatus by the number of anal-fin rays in females (11 vs. 10, respectively) (Ref. 76852).
