RESUMO
Thirty shells of Tamayoa (Tamayops) banghaasi (Thiele, 1927) from Ilha Grande, Rio de Janeiro, were analyzed with a stereomicroscop showing the following characteristics: discoid shell, without macrosculptures; ovate-lunate aperture without teeth. Thin, sharp and not-reflected lip; umbilicus with 1/5 of the shell's diameter; impressed suture, total whorls from 4 to 5.5; protoconch with 1.5 to 2 whorls; yellowish-amber, translucent and glossy periostracum. The morphology of the shells were discussed, as well as the shell's dimensions. The conchomorphological patterns are important for systematic studies of mollusks and this work presents data that can be used in future studies about the family.
