TLDR
Molecular data from domains D1, D2, and partial D3 of the 28S rDNA supply sufficient phylogenetic information to determine systematic relationships among the extant oyster taxa, from the major species groups to the family level, thus providing valuable characters that are able to supplement the paucity of morphological characters so far recognized.About:

Testing the New Animal Phylogeny: First Use of Combined Large-Subunit and Small-Subunit rRNA Gene Sequences to Classify the Protostomes
TL;DR: It is concluded that molecular systematists should use combined LSU + SSU rRNA genes rather than SSU alone for phylogenetic analyses, as both Ecdysozoa and Lophotrochozoa were strongly supported and the position of chaetognaths within protostomes remains uncertain.

Sphaeriid and Corbiculid Clams Represent Separate Heterodont Bivalve Radiations into Freshwater Environments
Joong Ki Park,Diarmaid Ó Foighil +1 more
TL;DR: This work constructed a representative molecular phylogeny, based on domains D1-D3 of the nuclear large subunit 28S rDNA, for 18 heterodont bivalves and for two oyster outgroup taxa, and found that the results do not support the monophyly of the Corbiculoidea and are consistent with the hypothesis that all three families of freshwaterheterodonts represent independent colonization events by marine ancestors.

Ribbon worm relationships: a phylogeny of the phylum Nemertea
TL;DR: The most extensive phylogenetic analysis to date, to the authors' knowledge, of higher–level nemertean relationships, based on sequence data from four different genes is presented, finding that well–supported clades are, in general, compatible with earlier, more limited, analyses.

Palaeoheterodont diversity (Mollusca: Trigonioida + Unionoida): what we know and what we wish we knew about freshwater mussel evolution
Daniel L. Graf,Kevin S. Cummings +1 more
TL;DR: From the ‘combined evidence’ topology (with problematic sequences excluded), the Unionoida is monophyletic on the basis of eight synapomorphies, including larval parasitism, brood protection, and restriction to freshwater.

Mitochondrial DNA and morphological identification of a new species of Crassostrea (Bivalvia: Ostreidae) cultured for centuries in the Pearl River Delta, Hong Kong, China
TL;DR: Phylogenetic analyses based on the cytochrome oxidase I and 16S data set show that Crassostrea hongkongensis is a genetically distinct taxon, and this is the first species of Ostreidae to be described genetically, in addition to shell characters.
