Beschreibung
The triviids, usually interpreted as Trivia arctica (Pulteney, 1799), are revised. Each species is discussed and compared with congenerates while type specimens are figured. The intraspecific variation is verbalized and illustrated by tabulations of measurements. Trivia corsica n. sp., is described from Calvi, Corsica. Lectotypes are designated for Trivia multilirata (G. B. Sowerby II, 1870) in the Natural History Museum London, UK and Trivia mollerati Locard, 1894 in the Muséum national d'Histoire naturelle Paris, France.. Pseudotrivia samariensis C. N. Cate, 1979 and Trivia tortuga C. N. Cate, 1979 are synonymized with Trivia hispanica C. N. Cate, 1979 and their type locality is corrected to the Pleistocene of Nieuwpoort, Belgium. The formerly fossil taxon Trivia merlini Fehse & Van de Haar, 2015 is now confirmed extant for the North Sea.
