Unmasking Antarctic mollusc lineages: novel evidence from philinoid snails (Gastropoda: Cephalaspidea)
Abstract Since its introduction, the genus Philine has epitomized numerous mollusc snails with strong morphological convergence. Recently, a molecular analysis including a wide taxon sampling split this group into four non‐sister families. Although they are especially diverse in cold and deep waters...

Abstract Since its introduction, the genus Philine has epitomized numerous mollusc snails with strong morphological convergence. Recently, a molecular analysis including a wide taxon sampling split this group into four non‐sister families. Although they are especially diverse in cold and deep waters, no comprehensive studies are available for the Antarctic counterparts. Here, our morpho‐anatomical and molecular data suggest major changes in the systematics of the group. From the eight known species, two are synonymized, Antarctophiline amoena with A. alata , and A. gouldi with A. gibba , and two are transferred to the genus Antarctophiline , namely A. apertissima comb.n. and A. falklandica comb.n.
