Abstract [en]

The family Turridae, once considered to encompass the entire diversity of Conoidea, excluding only the cone shells (family Conidae) and the auger shells (family Terebridae), has undergone significant redefinition based on both morphological and molecular data. Prior to this study, it included 15 Recent genera, comprising 209 species. However, a recent comprehensive analysis of an extensive dataset featuring 3,159 cytochrome c oxidase subunit I sequences has unveiled numerous species complexes, new species and previously undiscovered deep lineages. The newly proposed classification of Turridae based on an exon-capture phylogeny recognizes 24 clades, each worthy of genus rank, though only 13 of them had available names. As a result, 11 new genera have been described, namely Thielesyrinx n. gen., Shutogemmula n. gen., Mcleanigemmula n. gen., Pseudogemmula n. gen., Deceptigemmula n. gen., Oliveragemmula n. gen., Powelligemmula n. gen., Kilburnigemmula n. gen., Alisigemmula n. gen., Taylorigemmula n. gen. and Anisogemmula n. gen. With the exception of Thielesyrinx n. gen., species from all of these were previously classified within Gemmula, or Lophiotoma. Notably, some new genera, such as Deceptigemmula n. gen., Kilburnigemmula n. gen., Shutogemmula n. gen. and Taylorigemmula n. gen., cannot be morphologically differentiated, as similar species are found in other genera. Therefore, their distinction relies solely on molecular data. The name Eugemmula is re-instated from the synonymy of Gemmula. Purpuraturris is synonimized with Annulaturris, while Iotyrris with Xenuroturris. In total, we recognize 312 species/primary species hypotheses (PSHs) within the family. Molecular data were obtained for 212 species (among them 15 species complexes comprising in total 45 PSHs), mostly for the first time. A characteristic feature common to the entire family is the position of the relatively narrow anal sinus on the whorl periphery or immediately above it. Radula was examined in representatives of all genera. Although in several cases the radular morphology can aid genus differentiation (e.g. distinguishing Turris from Annulaturris), it is mostly a highly homoplastic structure, with very similar radular types occurring in distantly related genera.
