Integrative taxonomy reveals a new species of the soapfish genus Rypticus (Teleostei: Grammistidae) from the eastern Atlantic Ocean

Abstract

A new species of the soapfish genus Rypticus is described based on 14 specimens from the eastern Atlantic Ocean. The new species was previously misidentified as the greater soapfish, R. saponaceus, due to their similar appearance. However, it differs from R. saponaceus in several key characteristics, including a comparatively shorter head, snout and upper jaw, and a deeper body. Molecular data, obtained from the mitochondrial cytochrome oxidase I gene, strongly suggest the monophyly of the new species and support its description as new.
