The application of mixed nucleotide ⁄ doublet substitution models has recently received attention in RNA-based phylogenetics. Within a Bayesian approach, it was shown that mixed models outperformed analyses relying on simple nucleotide models. We analysed an mt RNA data set of dragonflies representing all major lineages of Anisoptera plus outgroups, using a mixed model in a Bayesian and parsimony (MP) approach. We used a published mt 16S rRNA secondary consensus structure model and inferred consensus models for the mt 12S rRNA and tRNA valine. Secondary structure information was used to set data partitions for paired and unpaired sites on which doublet or nucleotide models were applied, respectively. Several different doublet models are currently available of which we chose the most appropriate one by a Bayes factor test. The MP reconstructions relied on recoded data for paired sites in order to account for character covariance and an application of the ratchet strategy to find most parsimonious trees. Bayesian and parsimony reconstructions are partly differently resolved, indicating sensitivity of the reconstructions to model specification. Our analyses depict a tree in which the damselfly family Lestidae is sister group to a monophyletic clade Epiophlebia + Anisoptera, contradicting recent morphological and molecular work. In Bayesian analyses, we found a deep split between Libelluloidea and a clade ÔAeshnoideaÕ within Anisoptera largely congruent with TillyardÕs early ideas of anisopteran evolution, which had been based on evidently plesiomorphic character states. However, parsimony analysis did not support a clade ÔAeshnoideaÕ, but instead, placed Gomphidae as sister taxon to Libelluloidea. Monophyly of Libelluloidea is only modestly supported, and many inter-family relationships within Libelluloidea do not receive substantial support in Bayesian and parsimony analyses. We checked whether high Bayesian node support was inflated owing to either: (i) wrong secondary consensus structures; (ii) under-sampling of the MCMC process, thereby missing other local maxima; or (iii) unrealistic prior assumptions on topologies or branch lengths. We found that different consensus structure models exert strong influence on the reconstruction, which demonstrates the importance of taxon-specific realistic secondary structure models in RNA phylogenetics.

“…The phylogenetic relationships of zygopteran superfamilies are hotly debated, and based on morphological characters, are still not resolved (compare Fraser 1957; Carle 1982; Bechly 1996; Fleck et al. 2001; Rehn 2003).…”

Abstract. The limits and diffi culties related to the tools currently in use for palaeosynecological comparisons of faunas or fl oras of different geological periods are discussed. The new method of the Wagner parsimony Applied to Palaeosynecology Using Morphology (WAPUM method), is defi ned and tested on morphological characters gathered from two insect groups Odonatoptera and Thripida. The diffi culties related to the monophyly of the taxonomic groups used in the more traditional approaches are no longer a problem when using the WAPUM method. In the WAPUM a character is 'presence versus absence of species bearing a morphological structure'. The results obtained from use of the WAPUM minimize the number of changes among character states. Application of the WAPUM could reveal signals to confi rm or object the currently available scenarios for the global changes in the evolution of past diversity and disparity of organisms (major changes or global crises of diversity).Résumé. La parcimonie de Wagner sur base de caractères morphologiques : une nouvelle méthode pour les études paléosynécologiques. Les limites et diffi cultés inhérentes aux outils actuellement utilisés dans les comparaisons paléosynécologiques de faunes ou de fl ores de différentes périodes géologiques sont discutées. La nouvelle méthode de la parsimonie de Wagner appliquée à la paléosynécologie sur la base de caractères morphologiques (méthode WAPUM), est défi nie et testée à partir des caractères morphologiques de deux groupes d'insectes, les Odonatoptera et les Thripida. Les diffi cultés liées à la monophylie des groupes taxonomiques utilisés dans les approches plus traditionnelles disparaissent avec la méthode WAPUM. Dans l'approche WAPUM, un caractère est 'présence/absence d'une espèce portant une structure morphologique'. Les résultats obtenus à partir de la méthode WAPUM minimisent le nombre de changements d'état de caractères. Cet outil permet de tester les scénarios actuellement disponibles pour les changements globaux dans l'évolution de la diversité et de la disparité passée des organismes (changements majeurs ou crises globales de la diversité).

Abstract. The fi ndings of new specimens of Latibasaliidae and Frengueliidae in Northwest and Patagonia Argentina are noteworthy for the knowledge of these little know families and the explanation of their systematic position. The new fi ndings confi rm the phylogenetic position of these families. The morphology of the discoidal cell in both fore and hind wings of Frenguelia corresponds to the most basal epiproctophoran damsel-dragonfl ies, implying a Triassic age for the particular lineage of this family. The absence of any fossil record between Triassic and Eocene could be related to a highly specialized biology for these animals, maybe related to mountain rainforests as for Epiophlebia, unique surviving damsel-dragonfl y.
