The mitochondrial genomes of Macrotermes termites endemic to Ethiopia

The study of the fungus-growing termites genus Macrotermes in Africa remains notably limited, with the genus harboring hidden diversity that has eluded conventional taxonomy. Characterization of the mitochondrial genomes of these termite species represents an important biodiversity resource that could assist in resolving taxonomic ambiguities. The mitochondrial genomes of the two samples we sequenced, nominally Macrotermes subhyalinus (SE7) and Macrotermes herus (WE3), are 16,374 and 16,372 bp long respectively. We report congruent gene order for the two samples. Phylogenetic analysis using all protein coding genes in the mitochondrial genome recovered our WE3 mitochondrial genome as sister to a West African M. subhyalinus (JX144937) while our M. subhyalinus (SE7) mitochondrial genome is sister to M. falciger (KY224460). Our findings largely corroborate previous phylogenetic work on African Macrotermes and highlight the need for taxonomic scrutiny and increased taxonomic sampling of mitochondrial genomes within the clade.
