First description of the mitochondrial genomes of the Central American brocket deer Mazama temama (Kerr, 1792) and the Yucatán Peninsula brocket deer Odocoileus pandora Merriam, 1901.

backgroundThe Central American (Mazama temama) and the Yucatán Peninsula brocket deer (Odocoileus pandora) are deer species with cryptic habits, and little is known about their biology. Odocoileus pandora is listed as Vulnerable on the 2015 IUCN Red List of Threatened Species, while M. temama is considered Data Deficient; however, it currently faces a decreasing population trend. METHODS AND

resultsWe assembled the complete mitochondrial genome for two M. temama specimens and one complete and one partial for O. pandora from Illumina 150 bp paired-end reads. The mitogenomes of M. temama and O. pandora have a length of 16,479-16,480 and 16,419 bp, respectively, AT-biased; they consist of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one non-coding control region, most of them follow a transcription direction in the heavy strand of the molecule. The mitochondrial genome of O. pandora shows some particularities compared to other deer species, like a shorter control region of 987-990 bp and a cytochrome b gene with a length of 1,143 bp. Our phylogenetic analyses confirm the close affinity of M. temama to South American M. americana and the nested position of the genus Odocoileus, including O. pandora, into the genus Mazama.

conclusionsHere, we described for the first time the complete mitochondrial genome for these two species. While our study provides additional information about the taxonomic status of the northern neotropical brocket deer, further research is needed to solve the complicated taxonomy of neotropical deer.
