Redescription of the Indo-Australian filefish Acreichthys radiatus (Popta) (Monacanthidae, Tetraodontiformes). American Museum novitates ; no. 2727

Abstract

"Acreichthys radiatus (Popta, 1900) is redescribed in comparison to A. tomentosus, indicating that these two Indo-Australian species differ most obviously to the naked eye in color pattern, whereas microscopic examination shows that they also can be distinguished by the greater degree of scale spinule branching in tomentosus, in the smaller size at sexual maturity in radiatus, in radiatus usually having one less anal fin ray, and in several proportional measurements. They also differ in that the smaller species, radiatus, is found around coral reefs, whereas the habitat of tomentosus is inshore on sand and grass beds"--P. [1].
