title: Five new species and two records of Triphorinae (Caenogastropoda, Triphoridae) from Brazil.
abstract: Triphoridae is one of the most speciose families of marine mollusks, being mainly represented by the subfamily Triphorinae. The present study aims to describe five new species of Triphorinae, and to report two species in Brazil previously known only from the Caribbean: Nanaphora verbernei (Moolenbeek & Faber) comb. nov. is herein disregarded as belonging to the genus Cheirodonta, owing to differences especially related to shell morphology; Triphora portoricensis Rolán & Redfern has its known geographic distribution greatly increased, despite its non-planktotrophic development; Cheirodonta mizifio sp. nov. has a brown shell, with the median spiral cord emerging weakly in the beginning of sixth to eighth whorl of teleoconch; Eutriphora costai sp. nov. has a beige shell, with the median spiral cord emerging in the fifth whorl of teleoconch; Nanaphora leei sp. nov. has a large shell for the genus, with the median spiral cord emerging between the eighth and ninth whorl of teleoconch; Triphora charybdis sp. nov. has a white adapical spiral cord, brown median/abapical cords, with the median one usually emerging in the seventh whorl of teleoconch; Triphora scylla sp. nov. has a reticulated embryonic shell, with the median spiral cord of teleoconch emerging between the end of the sixth to the end of the tenth whorl.
