Abstract

ARCHANGELSKY, Miguel. Evolutionary scenarios in larvae and adults of Hydrophiloidea (Coleoptera) under different phylogenetic hypotheses. Rev. Soc. Entomol. Argent. [online]. 2007, vol.66, n.3-4, pp.103-111. ISSN 0373-5680.

The evolution of four bionomic and morphological characters is compared under five different phylogenetic hypotheses depicting the family relationships of the superfamily Hydrophiloidea (s.str.). These characters are: adult habitat (aquatic or riparian), larval habitat (terrestrial, aquatic or riparian), type of respiratory system in larvae (holopneustic or metapneustic) and number of abdominal segments in larvae (tenth segment not reduced or tenth segment reduced). Even though no phylogenetic hypothesis is favored above the others, they are evaluated according to how they explain the sequence of state changes of the above mentioned characters, and those that explain this sequence more parsimoniously are brought out.
