Abstract
    The recent genetic analysis of the muricid subfamily Ergalataxinae has led to a better understanding of this subfamily, but some species were left without appropriate generic assignments and the classification of others required revision. This knowledge gap is partially filled herein, with new combinations and the description of three new genera. The examination of new material, along with a careful re-examination of and comparison to existing material, resulted also in the identification of nine new species. These new genera and new species are described herein, lectotypes are designated and new combinations are given. The geographical range of all the new species is provided on maps. All new species are compared with related or similar species. The radula of Morula palmeri Powell, 1967 is illustrated for the first time. New genera: Claremontiella n. gen., type species Purpura nodulosa C.B. Adams, 1845; Murichorda n. gen., type species Purpura fiscellum Gmelin, 1791; Lauta n. gen., type species Ricinula parva Reeve, 1846. New species: Cytharomorula arta n. sp. from Reunion Island; C. absidata n. sp. from New Caledonia; C. elegantula n. sp. from the western Pacific Ocean; C. fatuhivaensis n. sp. from the Marquesas; C. manusuduirauti n. sp. from the Philippines; Orania pseudopacifica n. sp. from the Marquesas; Tenguella chinoi n. sp. from the eastern Indian and western Pacific Oceans; T. ericius n. sp. and T. chinoi from the western Pacific Ocean; and Claremontiella adiakritos n. sp. From western Mexico. Claremontiella adiakritos n. sp. was previously confused with Ricinula ferruginosa Reeve, 1846, a species which has been combined with Morula, Evokesia and Pascula, and which is a synonym of C. nodulosa (C.B. Adams, 1845). Lectotypes are designated for Fusus pachyrhaphe E.A. Smith, 1879 (= Orania pachyrhaphe) and Purpura granulata Duclos, 1832 (= Tenguella granulata). New combinations: Morula nodulosa (C.B. Adams, 1845) and Morula consanguinea (E.A. Smith, 1891) are transferred to Claremontiella n. gen.; Orania ornamentata Houart, 1995 is transferred to Cytharomorula; Morula parva (Reeve, 1846) is transferred to Lauta n. gen.; Muricodrupa fiscellum (Gmelin, 1791), Morula rumphiusi Houart, 1996 and Muricodrupa jacobsini Emerson & D'Attilio, 1985 are transferred to Murichorda n. gen.; Morula anaxares (Kiener, 1835) is transferred to Muricodrupa; Muricopsis carnicolor Bozzetti, 2009 and Morula taiwana Lai & Jung, 2012 are transferred to Orania; and Morula palmeri Powell, 1967 is transferred to Pascula. Cantharus albozonatus E.A. Smith, 1890 is removed from Orania, to which it was assigned in WoRMS (MolluscaBase 2018), and transferred to the genus Enginella Monterosato, 1917 (Buccinoidea, Pisaniidae). New synonymy: Sistrum ventricosulum G. & H. Nevill, 1875 is considered synonym of Morula echinata (Reeve, 1846).
