TL;DR: A large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes, is presented, the first phylogeny of the taxon to employ concatenated sequences of several genes.
TL;DR: A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper, in which fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae and Terebridae.
Abstract: A new genus-level classification of the Conoidea is presented, based on the molecular phylogeny of Puillandre et al. in the accompanying paper. Fifteen lineages are recognized and ranked as families to facilitate continuity in the treatment of the names Conidae (for ‘cones’) and Terebridae in their traditional usage. The hitherto polyphyletic ‘Turridae’ is now resolved as 13 monophyletic families, in which the 358 currently recognized genera and subgenera are placed, or tentatively allocated: Conorbidae (2 (sub)genera), Borsoniidae (34), Clathurellidae (21), Mitromorphidae (8), Mangeliidae (60), Raphitomidae (71), Cochlespiridae (9), Drilliidae (34), Pseudomelatomidae (=Crassispiridae) (59), Clavatulidae (14), Horaiclavidae new family (28), Turridae s. s. (16) and Strictispiridae (2). A diagnosis with description of the shell and radulae is provided for each of these families.
TL;DR: Four new species of the genus Psychomyia from China are described, illustrated and diagnosed: P. complexa n.
Abstract: Four new species of the genus Psychomyia from China are described, illustrated and diagnosed: P. complexa n. sp. (Zhe-jiang), P. conoidea n. sp. (Zhe-jiang), P. obtorta n. sp. (Jiang-xi), and P. tripetala n. sp. (Jiang-xi). Two known species, P. martynovi Hwang 1957 and P. extensa Li, Sun Yang 1999 are re-described and re-illustrated, with new distributional data.
TL;DR: A new molecular phylogeny based on a total of 102 conoidean genera (87 ‘turrids’, 5 cones and 10 terebrids) and three mitochondrial genes is presented, which recognizes 14 clades.
Abstract: The superfamily Conoidea constitutes one of the most diverse and taxonomically challenging groups among marine molluscs. Classifications based on shell or radular characters are highly contradictory and disputed. Whereas the monophyly of the Conidae and Terebridae has not been challenged, the other constituents of the superfamily are placed in a ‘trash’ group, the turrids, the non-monophyly of which has been demonstrated by anatomical and molecular evidence. We present here a new molecular phylogeny based on a total of 102 conoidean genera (87 ‘turrids’, 5 cones and 10 terebrids) and three mitochondrial genes [cytochrome oxidase I (COI), 12S rRNA and 16S rRNA]. The resulting tree recognizes 14 clades. When the Conidae (Conus s.l.) and Terebridae are ranked as families for consistency of usage, the ‘turrids’ must be split into 12 families of comparable rank. A new genuslevel classification of the Conoidea is published in an accompanying paper.
