Reduviidae is the second largest family of Heteroptera and most of them are important natural enemies of agricultural and forest pests. Most of the sequenced mitochondrial (mt) genomes in this family have the typical gene arrangement of insects and encode 37 coding genes (13 protein-coding genes, 22 tRNA genes and two rRNA genes). In the present study, we sequenced the mt genome of Phalantus geniculatus from the subfamily Peiratinae through high-throughput sequencing and encountered the duplication of tRNA genes for the first time in this subfamily. We identified 23 tRNA genes, including 22 tRNAs commonly found in insect mt genomes and an extra trnT (trnT2), which has high sequence similarity (96.9%) to trnT1. The presence of a "pseudo-trnP" in the non-coding region between trnT1 and trnT2 supports the hypothesis that the presence of two of an extra trnT can be explained by the tandem duplication-random loss (TDRL) model. Phylogenetic results inferred from mt genome sequences supported a sister relationship between Phymatinae and the remaining sampled subfamilies, as well as a paraphyletic Reduviinae. The present study highlights the utility of mt genomes in the phylogenetic study of Reduviidae based on the large scale taxon sampling in the future.

Proteins encoded by the mitochondrial genome or proteins encoded by the nuclear genome that are imported to and resident in the MITOCHONDRIA.
Double-stranded DNA of MITOCHONDRIA. In eukaryotes, the mitochondrial GENOME is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins.
Processes occurring in various organisms by which new genes arise, i.e. the duplication of a single gene. In contiguous gene duplication, the duplicated sequence coexists within the boundaries set by the start and stop signals for protein synthesis of the original, resulting in a larger transcription product and protein at the expense of the preexisting protein. In discrete gene duplication, the duplicated sequence is outside the start and stop signals, resulting in two independent genes (GENES, DUPLICATE) and gene products. Gene duplication may result in a MULTIGENE FAMILY; supergenes or PSEUDOGENES. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
