MARCENIUK, A. P., MENEZES, N. A. and BRITTO, M. R. (2012), Phylogenetic analysis of the family Ariidae (Ostariophysi: Siluriformes), with a hypothesis on the monophyly and relationships of the genera. Zoological Journal of the Linnean Society, 165: 534–669. doi: 10.1111/j.1096-3642.2012.00822.x
Ariid monophyly and intrafamilial relationships are investigated based on cladistic analysis of 230 morphological characters. Terminal taxa examined include whenever possible type-species, or the most morphologically similar species to the type-species of the nominal genera, and the largest possible number of species, including cleared and stained specimens, available in zoological collections. Previous hypotheses about monophyly of the Ariidae are strongly corroborated by new synapomorphies discovered in the present study. The subfamily Galeichthyinae and the remaining ariids are strongly supported by new morphological characters. The monotypic subfamily Bagreinae is recognized as the sister group to all nongaleichthyin ariids, supported by a large series of exclusive synapomorphies. A new concept of Ariinae is presented: the subfamily is found to be unequivocally monophyletic and includes all ariid genera, except Galeichthys and Bagre. New data supporting the monophyly of the genera included in the Ariinae are introduced and previous hypotheses of monophyly, species composition, morphological definition, and relationships are reviewed and discussed.
Interviewer:Mr Verccotti, what do you say to people who accuse you of exploiting Ron for your own purposes? Mr Vercotti:Well, it's totally untrue, David. Ever since I left Sicily I've been trying to do the best for Ron. Interviewer:And what's he going to do today? Mr Vercotti:He's going to split a railway carriage with his nose.
