COMMENTS OF SPECIES OF SOLARIELLA AND LAMELLITROCHUS (TROCHIDAE, SOLARIELLINAE) FROM THE CONTINENTAL SLOPE OF NORTHEAST BRAZIL, WITH THE DESCRIPTION OF A NEW SPECIES

Resumo

Five species of Solariella and three species of Lamellitrochus were identified from the continental shelf and slope of Northeast Brazil, and were revised based on morphology, the original descriptions and type material. Solariella quinni sp. n. is described based on its conchology, presenting wide incidence in coastal areas of Pernambuco off the state. Among the species known thus far for the Eastern Atlantic, S. quinni shows affinities with Solariella cristata Quinn, 1992 for having a conical, turbinate shell, deep umbilication, weakly convex base and spiral ornaments developed on the body whorl, but may be separated for showing 3 spiral cords on the 1st whorl, compared to 4 to 5 spiral cords in S. cristata. S. quinni is considered endemic to Northeast Brazil.
