Abstract
The recent description of a distinctive new pimelodid catfish, Pimelabditus moli Parisi & Lundberg, 2009, from the Maroni River basin of Suriname and French Guiana, added an unresolved taxon to the family. Here we include P. moll in ongoing molecular and morphological phylogenetic studies of the Pimelodidae. We sequenced > 7.5 KB of aligned bases from the nuclear rag1 and rag2 genes and the mitochondrial mt-rnr1, mt-rnr2 and mt-cyb genes. Results provide strong support for the placement of P. moli as the sister taxon to Pimelodus ornatus Kner, 1858. We also describe a structurally complex pterotic-epioccipital fossa shared by P. moli and P. ornatus that provides an unambiguous synapomorphy indicating their close relationship. Furthermore, the molecular and morphological data recover the P. moli -P. ornatus Clade as the sister group to the Calophysus-Pimelodus Clade. Pimelabditus moli is a rare species, known from just five specimens. Notes on the provenance, capture and habitat of P. moli are provided.
