Characterization of the complete mitochondrial genome of the invasive tramp ant Cardiocondyla obscurior (Hymenoptera: Formicidae: Myrmicinae)

Abstract

Cardiocondyla obscurior is native to Southeast Asia but has become successfully established throughout the tropics and subtropics. Here, its mitochondrial genome was assembled from Illumina sequencing data. The genome is 15,213 bp long with a highly asymmetric nucleotide composition, and harbors the typical set of 37 mitochondrial genes and one noncoding control region. All PCGs are initiated with typical ATN codons and are terminated with TAA, TAG or the incomplete T(aa) codon. The control region has a remarkably high A + T content (90.8%) and harbors a 34-bp-long tandem repeat (TA)₁₇. Phylogenetic analysis suggests that it is closely related to Pristomyrmex punctatus.
