Generic interrelationships within the Spionidae (Annelida: Polychaeta) [PDF]

open access: bronzeZoological Journal of the Linnean Society, 1997
Abstract The phylogenetic relationships of spionid genera are estimated from parsimony analyses of morphological characters, with Trochochaetidae, Poecilochaetidae and Uncispionidae as outgroups. A first analysis of currently recognised genera proved inconclusive and even exclusion of six of the most polymorphic genera resulted in 13 305 equally ...
