In the present study, mitogenomes of the species Trachypenaeus curvirostris and Parapenaeus fissuroides (Decapoda: Dendrobranchiata: Penaeidae) were sequenced. The total lengths of the two species were 15,956 bp and 15,937 bp in length with A + T biases of 67.08% and 67.69%, respectively. Both two species showed positive AT skews (0.016, 0.058) and negative GC skews (-0.254, -0.310). Both mitogenomes contained 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes. Results of phylogenetic analyses support close relationships among Aristeidae, Benthesicymidae and Solenoceridae. The family Sicyoniidae was observed to be deeply nested within Penaeidae. Within Penaeidae, T. curvirostris and P. fissuroides were most closely related to the genus Parapenaeopsis and Metapenaeopsis, respectively, indicated that these two species belong to Penaeidae. These results will help to better understand the evolutionary position of Penaeidae and provide reference for further phylogenetic research on Penaeoidea species.
