The complete mitogenome sequence of the Chinese longsnout catfish Leiocassis longirostris was determined using long-polymerase chain reaction (long-PCR) and directly sequenced with primer walking method. The complete mtDNA was 16,534 bp in length and contained 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control region (D-loop), the gene composition/order of which was identical to that observed in most other vertebrates. Phylogenetic relationship of 15 ostariophysan fishes was reconstructed using Bayesian inference and maximum likelihood methods based on a total of 15,658 nucleotides from all the 13 protein-coding, two rRNA, and 22 tRNA genes, using recently developed models of rate autocorrelation, which resolved the phylogenetic relationship of the major ostariophysan lineages with a high statistical support. The present result was consistent with some previous molecular cladistic work which supported the grouping of (((((Characiformes, Gymnotiformes), Siluriformes), Cypriniformes), Gonorynchiformes), outgroup). The Chinese longsnout catfish together with the Bagrid catfish (both from the same family Bagridae) had a closer affinity with Amblycipitidae than with other four analyzed catfish families. The relaxed molecular clock method incorporated into the program BEAST vl.5.3 was used to estimate divergence dates among ostariophysan lineages, which revealed that the major ostariophysan lineages diversified in the middle Jurassic (around 164.5 million years ago (Mya)) and the split of Leiocassis/Pseudobagrus occurred in the Oligocene to Miocene (8.9-25.1 Mya). The time-calibrated tree generated in this study would provide a powerful evolutionary tool for broad-scale comparative studies of the catfishes and the ostariophysan fishes.
