Original description: Originally described by Smith & Radcliffe in Radcliffe, 1911:246, Pls. 20-21. Proceedings of the U. S. Natural Museum, V 41 (no. 1853) as Amia compressa.
Description was based on specimens collected at Bisucay I., Cuyos Is., Philippines. Validated by Hayashi in Matsuda et al. 1984 as Apogon compressa. Later validated by Paxton et al, 1989, and Allen 1993 as Apogon compressus.

Vernacular name: Ochre-striped cardinalfish, Split-banded cardinalfish, Blue-eyed cardinalfish

Word origin: Apogon is from the Greek roots apo
meaning from, off, or away; and gon meaning offspring. (Perhaps due to the mouthbrooding
characteristics of this family).. The genus compressus appears to be a combination of the Latin roots com meaning together; and pressus meaning pressed; (‘pressed together”)
