“…The Ocenebrinae (as represented by Nucella, Acanthina and, for 28S, Eupleura) are monophyletic in all trees, in agreement with previous morphological (Kool, 1993a, b;Tan, 2003) and molecular (Marko & Vermeij, 1999) results. We found no evidence of a sister relationship between Rapaninae and Ocenebrinae, in contrast to the results of Tan (2003).…”

“…Marko & Vermeij (1999) published a molecular phylogeny of mainly eastern Pacific ocenebrines, with two rapanines as the outgroup, which supported monophyly of the Ocenebrinae. Two other molecular studies focused on relationships within the Coralliophilinae, but also showed support for a sister relationship between the Coralliophilinae and the Rapaninae, although fewer than six non-coralliophiline taxa were sampled (Oliverio & Mariottini, 2001;Oliverio, Cervelli & Mariottini, 2002).…”

The previous phylogenetic hypotheses for Rapaninae, a large and taxonomically perplexing subfamily of the Muricidae, have been based on morphological characters. These studies concluded that the subfamily is distinct from the Ocenebrinae and that some 'ergalataxine' muricids are contained within the Rapaninae. We tested these hypotheses using DNA sequence data (one mitochondrial and one nuclear gene) from 35 species across the Muricidae. The monophyly of the Rapaninae and Ergalataxinae is supported, but relationships among these and other muricid subfamilies are not resolved. We discuss phylogeny of the sampled genera within the Rapaninae and Ergalataxinae, and show that Thais (Rapaninae) and Morula (Ergalataxinae) are polyphyletic.

“…Four major clades were consistently recovered in both multiple genes analyses (ML and BA): clade A included Xanthochorus P. Fischer, 1884, Acanthina , Chorus and Acanthinucella Cooke, 1918; clade B included Ceratostoma , Mexacanthina Marko & Vermeij, , Ocinebrellus , eastern Pacific ‘ Ocinebrina ’ and Nucella ; clade C included the genus Eupleura H. & A. Adams, 1853; clade D included Jaton , Urosalpinx Stimpson, 1865, Hadriania , Ocenebra and the north‐eastern Atlantic and Mediterranean Ocinebrina .…”

“…Marko & Vermeij () divided eastern Pacific Ocenebrinae into two clades: the Ocinebrina ‐clade including Ceratostoma , Mexacanthina , eastern Pacific ‘ Ocinebrina ’ and Nucella ; and the Acanthina ‐clade for Acanthina and Acanthinucella . We found that Ocinebrina , as traditionally conceived, that is including eastern Pacific and eastern Atlantic/Mediterranean lineages, is polyphyletic.…”

A molecular phylogenetic framework for the subfamily Ocenebrinae (Gastropoda, Muricidae)

The Ocenebrinae is a subfamily of marine predatory gastropods known as oyster and mussel drills. Their current phylogenetic framework is traditionally based on shell and radular\ud characters, but a consensus on relationships among genera is still lacking. We investigated the molecular phylogeny of Ocenebrinae using 50 species and DNA data from one nuclear (28S) and two mitochondrial (COI and 16S) genes, the largest data set so far assembled for this subfamily. We found support for the monophyly of the Ocenebrinae, and species were divided into four major lineages. Within groups, genera had similar geographic distributions, suggesting that except in a few cases, species diversification within clades occurred without range expansions. We discuss the phylogenetic distribution of a labral tooth and a sealed siphonal canal, two characteristic ocenebrine features. We also show that Ocinebrina species in the north-eastern Pacific are not monophyletic with north-eastern Atlantic and Mediterranean species, and that the Ocinebrina edwardsii species complex belongs to Ocenebra

“…One of the major determinants of molluscan preservation is shell mineralogy (Harper 1998), but the Cretaceous gastropods studied here, with only one or two exceptions, all consist of the same form of calcium carbonate (aragonite). Reid et al (1996); Tegula, Hellberg (1998) Fortunato (1998); Helcion versus Cymbula, Koufopanou et al (1999); Acanthinucella versus Nucella, Marko & Vermeij (1999); Littoraria (Littorinopsis) versus L. (Palustorina) versus 'clade 6', Reid (1999); Chionopsis s.s. versus Puberella, Roopnarine (2001). Shell size is another factor known to influence preservation and sampling, but exclusion of Cretaceous gastropod genera where the median size of species is less than 1 cm only strengthens the relations reported here.…”

The notion of a positive relation between geographical range and speciation rate or speciation probability may go back to Darwin, but a negative relation between these parameters is equally plausible. Here, we test these alternatives in fossil and living molluscan taxa. Late Cretaceous gastropod genera exhibit a strong negative relation between the geographical ranges of constituent species and speciation rate per species per million years; this result is robust to sampling biases against small-bodied taxa and is not attributable to phylogenetic effects. They also exhibit weak inverse or non-significant relations between geographical range and (i) the total number of species produced over the 18 million year timeframe, and (ii) the number of species in a single timeplane. Sister-group comparisons using extant molluscan species also show a non-significant relation between median geographical range and species richness of genera. These results support the view that the factors promoting broad geographical ranges also tend to damp speciation rates. They also demonstrate that a strong inverse relation between per-species speciation rate and geographical range need not be reflected in analyses conducted within a single timeplane, underscoring the inadequacy of treating net speciation as a proxy for raw per-taxon rates.
