Phylogeny and evolutionary radiation in seasonal rachovine killifishes: biogeographical and taxonomical implications (2014 Wilson J. E. M. Costa)



A phylogenetic analysis combining available mitochondrial DNA sequences (total of 3,339 bp) and 161 morphological characters for 22 species of rachovine genera (Aphyolebias, Austrofundulus, Gnatholebias, Llanolebias, Micromoema, Moema, Neofundulus, Pterolebias, Rachovia, Renova, Terranatos, and Trigonectes), and 16 outgroups, supports monophyly of the group containing genera endemic to the Orinoco river basin and adjacent coastal drainages. Results of the present analysis are compared to previous studies. The tree topology indicates that the genera Moema and Rachovia as presently delimited are paraphyletic; consequently, Aphyolebias and Austrofundulus are respectively placed in the synonymy of Moema and Rachovia. This study also indicates that rachovines were in the past geographically restricted to the Amazonas-Paraguay area where diversification in niche exploitation was constrained by competition with sympatric members of older seasonal fish lineages. Rachovines later reached the Orinoco basin and adjacent coastal drainages by dispersal through the Paleo-Amazonas river basin, when major evolutionary radiation taken place.
