A New Species of Angaria Röding, 1798 (Gastropoda: Angariidae) from North-Western Sumbawa, Indonesia.

This paper describes a new species of Angaria Röding, 1798 from north-western Sumbawa, Indonesia. In general appearance it resembles some forms of the species Angaria delphinus (Linnaeus, 1758) found in the same area and on neighbouring islands. The new species differs from it in sculptural features and interstitial markings, which it shares with two Vietnamese species, Angaria fratrummonsecourorum Günther, 2013 and Angaria guntheri Thach, 2018.
