Description of the complete mitochondrial genome of the Van Gelder's bat Bauerus dubiaquercus (Chiroptera: Vespertilionidae)

Bauerus dubiaquercus is a vespertilionid bat species found from Mexico to Costa Rica, including insular populations on the Tres Marias Islands. It has an insectivorous diet and inhabits tropical evergreen, tropical deciduous, tropical subdeciduous, and cloud forests. In this study, we assembled and characterized the complete mitochondrial genome of B. dubiaquercus. The publication of this mitogenome represents a valuable contribution to the genetic data available for this genus and may serve as a reference for future molecular studies on Bauerus or its relationship with other species in the family Vespertilionidae. The mitogenome is 16,446 bp long and contains the typical 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, two origins of replication, and a control region (CR). Its gene order is identical to that previously reported for bats. The secondary structure of the tRNA genes exhibits the typical cloverleaf shape, except for tRNA-Serine-1, which lacks the DHU arm. Nucleotide composition and codon usage patterns are consistent with those reported for Chiroptera. Selective pressure analysis of the protein-coding genes indicates strong purifying selection across all genes. Within the control region, we identified three microsatellites and one tandem repeat. A phylogenomic analysis supports the placement of Bauerus dubiaquercus within the tribe Antrozoini, closely related to the genus Rhogeessa, consistent with previous taxonomic proposals.
