摘要

The family Spinturnicidae belongs to the suborder Monogynapsida, superfamily Dermanyssoidea, and exclusively parasitizes the body surface of bats. In the present study, we determined the complete mitochondrial genome of Spinturnix psi, a species of bat mite, and subsequently conducted a comprehensive analysis of its genomic information. The mitochondrial genome of S. psi has a length of 16,299 bp, an AT content of 76.63%, an AT skew of -0.01, and a GC skew of -0.23. Analysis of RSCU revealed a clear usage preference for codons such as AAA, UUU, AAU, UAU, AUU, and UAA. A gene rearrangement involving trnQ was observed. Phylogenetic analysis indicated a close genetic relationship between S. psi and the family Laelapidae. These findings contribute to the molecular data available for Spinturnicidae and provide useful references for species identification. Additionally, these results lay the foundation for future studies on the potential transmission of pathogens carried by bat mites.
