Abstract

Turrancilla, a small genus of Ancillariidae, is revised based on molecular (partial cox1 sequences) and morphological data. Six species are attributed to the genus based on both molecular and morphological evidence, including one new species, T. heraldei sp. nov., from the Philippines. Two additional species are included based on morphological data alone. The status of one of these, T. apicalis Kira, 1959, from Japan, remains uncertain pending further data. One species, T. williamsoni Petuch, 1987, is excluded and provisionally assigned to Amalda. In conchological characteristics, Turrancilla can closely resemble Amalda but is readily distinguished by its radular features. The genus is primarily confined to upper bathyal depths of the Pacific, with one species, T. akontistes reaching western Indian Ocean (from Zanzibar to Mozambique and Madagascar) and one, T. sibuetae, recorded in the eastern Atlantic.
