Revision of Platydoris angustipes and description of a new species of Platydoris (Gastropoda: Nudibranchia) from southeastern Brazil based on comparative morphology

Platydoris angustipes (Mörch, 1863) is a common nudibranch in the Western Atlantic, ranging from Florida, USA, to Rio de Janeiro, Brazil. In this study, we examined the anatomy of P. angustipes along its distribution, including its type material. Our analysis shows consistent differences between the...

Description
Summary:Platydoris angustipes (Mörch, 1863) is a common nudibranch in the Western Atlantic, ranging from Florida, USA, to Rio de Janeiro, Brazil. In this study, we examined the anatomy of P. angustipes along its distribution, including its type material. Our analysis shows consistent differences between the Caribbean and Brazilian populations, mainly in the reproductive system, radular teeth and odontophore musculature. This strongly suggests that the two populations actually belong to distinct species. The Brazilian population is described herein as a new species, Platydoris guarani sp. n.
