We describe and illustrate two new species of Sosibia from China: Sosibia gibba sp. nov. and Sosibia ovata sp. nov. This report includes a key to Sosibia species from China and a description of the distribution area in China. The two mitochondrial genomes of these new Sosibia species were sequenced and annotated for the first time. The compositional biases, codon usage, nucleotide composition, and construct tRNA secondary structures of the two mitogenomes were analyzed. The phylogenetic relationships based on the mitogenomes using Bayesian inference and maximum likelihood methods supported the monophyly of Necrosciinae and divided it into two distinct clades: A: (Sipyloidea + [Sosibia + Calvisia]); and B: (Neohirasea + Micadina).
