The carboniferous and permian Aeduellidae (Pisces, Actinopterygii): systematics and preliminary phylogenic study.

The aeduellid genera and species already known are presented. A phylogenetic analysis, involving 12 other actinopterygians and a porolepiform outgroup, confirms that the Aeduellidae are a natural group. But their interrelationships are not cleared up completely, probably because of many missing data; in particular one genus, Bourbonnella, appears as paraphyletic. This family has a mosaic of plesiomorphic and apomorphic actinopterygian characters; their relationships with the other basal Actinopteri (= Palaeoniscimorpha) are not clearer. In fact the analysis does not show particular affinities with the groups with which they have been tentively compared in the past.
