Description of a new Apertifusus (Mollusca: Gastropoda: Fasciolariidae), followed by an in-depth look to other species of the family Fasciolariidae in Gabonese, Angolan and Namibian waters, pp. 1-22, 1 map, 6 text figs, 2 tables, pls I-X, by Frank Nolf
Abstract: A new Apertifusus from Angola is described and compared with its congeners from the same waters. A survey of Angolan and Gabonese species of the family FASCIOLARIIDAE makes it clear that there is very little difference between Viridifusus albinus (A. Adams, 1856) and large specimens of V. mollis (G.B. Sowerby III, 1913). Another comparison reveals that Apertifusus maritzaallaryae (Cossignani & Allary, 2019) is a junior synonym of A. caparti (Adam & Knudsen, 1955).
