The Complete Mitochondrial Genome of Northeast Asian Rove Beetle, Lordithon arcuatus (Solsky, 1871) and Performance of Site-Specific Mixture Models in Building the Mitogenomic Phylogeny of Staphylinidae (Insecta: Coleoptera)

Lordithon species are typically mushroom-dwelling rove beetles that devour maggots. This study presents the mitogenome of a arcuatus specimen was procured from Changbai Mountain in Jilin Province China. The is 18,290 bp long and comprises 13 protein-coding genes, 22 tRNAs, 2 rRNAs. base composition as follows: A = 38.80%, T 37.93%, G 8.94%, C 14.32%. Maximum likelihood Bayesian phylogenetic trees were constructed using 68 representative staphylinid species, which showed Lordithon, Bolitobius, Ischnosoma form stable fully supported Mycetoporinae clade, whereas there no consensus regarding relationships among Tachyporinae taxa. Additionally, performance site-specific mixture models for inferring phylogeny staphylinids mitogenomic data assessed. results suggest heterotachy should be used with caution, they may result incorrect topology delusive precedence AIC- or BIC-based model selection.
