New taxa and new synonymy in Muricidae (Neogastropoda: Pagodulinae, Trophoninae, Ocenebrinae) from the Northeast Pacific

The results of an extensive examination of northeast Pacific muricid gastropods ranging from Aleutian Islands, Alaska, to mid-Baja California, is presented. Two new genera and 26 new species are described: In Pagodulinae: Abyssotrophon fusiformis n. sp., A. newmani n. sp., Boreotrophon cascadiensis...

Description
Summary:The results of an extensive examination of northeast Pacific muricid gastropods ranging from Aleutian Islands, Alaska, to mid-Baja California, is presented. Two new genera and 26 new species are described: In Pagodulinae: Abyssotrophon fusiformis n. sp., A. newmani n. sp., Boreotrophon cascadiensis n. sp., B. cordellensis n. sp., B. cortesianus n. sp., B. obesus n. sp., B. subapolyonis n. sp., B. vancouverensis n. sp., B. aleuticus n. sp., B. pseudotripherus n. sp., B. santarosensis n. sp., B. tannerensis n. sp. In Trophoninae: Warenia, n. gen., Scabrotrophon buldirensis n. sp, S. kantori n. sp., S. lima n. sp., S. macleani n. sp., S. moresbyensis n. sp., S. norafosterae n. sp., S. trifidus n. sp., Nipponotrophon exquisitus n. sp. In Ocenebrinae: Paciocinebrina n. gen., Nucella angustior n. sp., Paciocinebrina benitoensis n. sp., P. macleani n. sp., P. neobarbarensis n. sp., P. pseudomunda n. sp., P. thelmacrowae n. sp. New synonymy: Boreotrophon kamchatkanus Dall, 1902 (+ Trophonopsis nanus Ergorov, 1994); Paciocinebrina atropurpurea (Carpenter, 1865) (+ Tritonalia interfossa var. clathrata Dall, 1919, Ocinebra rubra Baker, 1891, Tritonalia tracheia Dall, 1919); P. barbarensis (Gabb, 1865) (+ Tritonalia interfossa var. beta Dall, 1919, Ocenebra keenae Bormann, 1946); P. circumtexta (Stearns, 1871) (+ Ocinebra circumtexta var. aurantia Stearns, 1895, Tritonalia circumtexta var. citrica Dall, 1919, Tritonalia lurida var. rotunda Dall, 1919); P. foveolata (Hinds, 1844) (+Tritonalia epiphanea Dall, 1919, Tritonalia fusconotata Dall, 1919); P. gracillima (Stearns, 1871) (+ Tritonalia gracillima var. obesa Dall, 1919, Ocinebra stearnsi Hemphill, 1911); P. interfossa (Carpenter, 1864) (+ Tritonalia interfossa alpha Dall, 1921); P. lurida (Middendorff, 1848) (+ Vitularia aspera Baird, 1863), P. sclera (Dall, 1919) (+ Coralliophila (Pseudomurex) kincaidi Dall, 1919). Generic assignments are changed for the following taxa: Boreotrophon kamchatkanus Dall, 1902; Warenia elegantula (Dall, 1907); Scabrotrophon stuarti (E.A. Smith, 1880); Paciocinebrina atropurpurea (Carpenter, 1865), P. barbarensis (Gabb, 1865), P. circumtexta (Stearns, 1871), P. crispatissima (Berry, 1953), P. foveolata (Hinds, 1844), P. fraseri (Oldroyd, 1920), P. gracillima (Stearns, 1871), P. grippi (Dall, 1911), P. interfossa (Carpenter, 1864), P. lurida (Middendorff, 1848), P. minor (Dall, 1919), P. munda (Carpenter, 1864), P. seftoni (Chace, 1958), P. sclera (Dall, 1919). Boreotrophon alborostratus Taki, 1938, is reinstated. Abyssotrophon Egorov, 1993 and Nodulotrophon Habe & Ito, 1965 are here assigned to Pagodulinae Barco et al., 2012, based on radula morphology.
