TECHNICAL NOTE
The complete mitochondrial genome of the surubim Pseudoplatystoma corruscans (Siluriformes: Pimelodidae) and mitochondrial phylogenomics of catfishes confirm monophyly of Siluriformes families Francisco Prosdocimi1 · Violeta Perini1 · Ana Teresa Nogueira Dumans1,2 · Carolina Furtado3 · Daniel Cardoso de Carvalho4 Received: 6 February 2017 / Accepted: 10 March 2017 © Springer Science+Business Media Dordrecht 2017
Abstract Surubim (Pseudoplatystoma corruscans) is a large catfish that can reach 120 Kg. Their populations have been declining lately. Here, we describe for the first time the complete mitochondrial genome for an individual from this species. The circularized mitogenome followed the expected pattern for vertebrates, being 16,123 bp in length. It contained 13 protein-coding genes, 2 rRNA genes, 22 tRNAs and a putative non-coding control region. A maximum-likelihood phylogenomic tree was constructed using a supermatrix dataset contaning all protein-coding genes concatenated for the mitogenome of 36 Siluriformes species and 2 outgroups. The tree provided insights about the relationship of surubim to other catfishes and it is consistent with previous phylogenies. It evidenced monophyly for all 11 catfish families analyzed. Further studies using nuclear markers should be performed to clarify sister relations inside Siluriformes clade. Keywords Surubim · Mitogenome · Phylogenomics · Siluriformes

The catfish Pseudoplatystoma corruscans, commonly named surubim or pintado, is a large piscivorous fish that can reach 120 kg (Sato et al. 2003). P. corruscans is a migratory species and their schools can swim many kilometers to spawn in the rainy season (Carolsfeld et al. 2003). It is one of the most important fishery resources from the South American river basins of (i) Paraná and (ii) São Francisco (Godinho and Godinho 2003; Godinho et al. 1997). Distinct Evolutionary Significant Units were previously reported to inhabit each river system (Carvalho et al. 2012). Their populations have been declining mainly because of overfishing and river damming (Godinho et al. 2007). In the present study, we describe for the first time the complete mitochondrial genome for an individual from this species and explore the phylogenomic relationships among 36 Siluriformes species that present their complete mitochondrial genome available in GenBank. Specimens of P. corruscans were collected in Pandeiros river located at the São Francisco ri
