A study was conducted to investigate the evolutionary relationships of from Oman, in the southeastern part of the Arabian Peninsula. Sequences of the mitochondrial and the nuclear large-subunit ribosomal RNA (LSU rRNA, ) genes were used to investigate the populations of across their distribution in Oman to determine their relationships with other species. Our findings indicate that in Oman is a member of an East African clade, distinct from those in West Africa. Analyses of the showed that there is base composition bias among the taxa (non-stationarity) that has not been considered in earlier studies. We provide the first report of pseudogene copies of in that are differentially amplified.
