The study of the material obtained in São Tomé and Principe Islands during two expeditions in the years 1989 and 1990, have yielded a new trochid species with Solariella, which for its morphological and radular characters belongs to the subfamily Lirulariinae. This species is described as new for science within the genus Lirularia and its morphological characteristics of shell, soft parts and radula are commented on. The assignment to this genus of other two species of the West African coast is discussed
