“…Molecular phylogenetic studies of the Palaeoheterodonta to date have applied a variety of markers, but the majority have been limited in scope to interspecific relationships between Nearctic or Australasian taxa (e.g. Mulvey et al ., 1997; Lydeard, Minton & Williams, 2000; Roe et al ., 2001; Serb & Lydeard, 2003; Serb et al ., 2003; Baker et al ., 2004; Hughes et al ., 2004; Campbell et al ., 2005); these have been reviewed recently by Roe & Hoeh (2003). The large mitochondrial ribosomal subunit (16S) has been applied in restricted capacity to the problem of subfamilial relationships within the Unionidae of eastern North America (Lydeard et al ., 1996; Campbell et al ., 2005) and China (Huang et al ., 2002).…”

The Palaeoheterodonta is a diverse clade consisting of the freshwater bivalve order Unionoida and its marine sister group, Neotrigonia . Neotrigonia is the sole surviving genus of the Trigonioida, known from only six species in Australian waters. Unionoids (freshwater mussels), in contrast, are widespread on all continents except Antarctica and are represented by c . 900 species. Discussion is biased towards the freshwater mussel condition, but Neotrigonia is crucial as a 'living fossil' for establishing the plesiomorphic states of unionoid synapomorphies. Neotrigonia retains many of the characters of the ancestral heteroconch. Our object is to provide evidential support for the natural classification of the extant Palaeoheterodonta. A supermatrix of 50 taxa and 1183 characters was constructed from 62 previously published DNA sequences of mitochondrial cytochrome oxidase subunit I (COI) and 28S nuclear ribosomal DNA, 15 novel sequences, and 59 morphological characters. Published COI sequences for Coelatura aegyptiaca , Pseudomulleria dalyi , and Obliquaria reflexa were treated as potentially problematic because of their inconsistency under different methodological assumptions and conflict with other datasets. Each partition was analysed under the criterion of parsimony separately and in combined analyses; analyses were run both with and without the problematic sequences. From our '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. The order is composed of six families in two superfamilies, Unionoidea and Etherioidea: ((Unionidae + Margaritiferidae) + (Hyriidae + (Etheriidae + (Mycetopodidae + Iridinidae)))). The morphological synapomorphies of these taxa are discussed with an emphasis on both the diagnosing of taxa and highlighting areas of ambiguity and missing data. Three appendices provide descriptions of the morphological characters (Appendix 1), a diagnosis of apomorphies for all branches of the phylogeny (Appendix 2), and a family-level classification of the extant Palaeoheterodonta, including a complete synonymy (Appendix 3).

Genetic variability of a freshwater bivalve Diplodon chilensis from three Nahuelbuta lakes was described. Each lake shows geographic barriers and environmental characteristics as a consequence of geomorphologic and antropic events. Our results shows that only Lleu-Lleu lake was in Hardy-Weinberg equilibrium (P<0.05). All populations show gametic desequilibrium (P < 0.001), as an evidence of the species' life cycle. There are heterozygote deficiencies (Fis) in Laguna La Posada and Laguna Chica de San Pedro. Global Fst (0.027) and AMOVA test values for pooling subpopulation show non structured population, as an evidence of recent migration process.Keywords: Diplodon chilensis, linkage disequilibrium, heterozygote deficit, Hardy-Weinberg equilibrium, lenthic systems. RESUMENSe describe la variabilidad genética del bivalvo dulceacuícola Diplodon chilensis proveniente de tres lagos Nahuelbutanos, cada uno de los cuales presenta barreras geográficas y diferencias ambientales reconocibles como consecuencia de diversos eventos geomorfológicos y antrópicos. Nuestros resultados revelaron que sólo Lago Lleu-Lleu se encuentra de equilibrio Hardy-Weinberg (P< 0.05). El desequilibrio gamético se manifestó en las tres poblaciones p< 0.001 lo que podría explicarse por la complejidad de su ciclo reproductivo. La Posada y Laguna Chica de San Pedro presentan déficit de heterocigotos (Fis). Los valores de Fst global (0.027) y AMOVA para la población total indican que estas poblaciones no están estructuradas lo que sugiere procesos de migración recientes a través de los cursos de agua.Palabras clave: Diplodon chilensis, desequilibrio gamético, déficit de heterocigotos, equilibrio Hardy-Weinberg, sistemas lénticos.
