Abstract

Part of the genus Lioconcha
Mörch, 1853 is reviewed. Species strongly resembling Lioconcha
castrensis (Linnaeus, 1758) are discussed and two new
species are described: Lioconcha arabaya n. sp. from the
Northwest Indian Ocean and Lioconcha rumphii n. sp. from
Thailand and Sumatra. These three species, together with Lioconcha
macaulayi Lamprell & Healy, 2002, share many
morphological similarities and we suspect them to be closely related.
They are referred to as the Lioconcha castrensis species group.
Furthermore, lectotypes of Venus castrensis Linnaeus,
1758, and Venus fulminea Röding, 1798, are designated. The
latter is considered a junior synonym of V. castrensis.
