[1] Lowe’s Callanthias paradiseus is now known to be a synonym of Lepimphis ruber, described by Constantine Samuel Rafinesque in 1810 from Palermo on Sicily.

[2] The relationships of Callianthias have been subject of some uncertainty in the past and they were previously regarded as a very aberrant genus of the Serranidae, while other authors placed it in the Grammatidae.

[3] Callanthias is one of two genera in the family Callanthiidae, the other is Grammatonotus, which the 5th edition of Fishes of the World places in the order Spariformes.

Lowe named the genus this because he described its type species, Callanthias paradisaeus, as "a most elegant little fish" and "almost as rare as beautiful" and noted the resemblance on form and dentition to Anthias.

[3] Callanthias splendid perches are found in temperate and subtropical seas with most species occurring in the Pacific Ocean.
