Mitochondrial and Nuclear Gene Phylogeny of Pseudotrapelus (Sauria: Agamidae) with Considerations on the Hybridization and mtDNA Introgression between Species

Ekaterina Melnikova, Daniel Melnikov, Natalia Ananjeva

Abstract


Presented is first preliminary data on mitochondrial (mt) (COI) and nuclear (RAG1) DNA phylogeny of Pseudotrapelus. Pseudotrapelus is a monophyletic genus, being sister to south Arabian Acanthocercus yemensis. Two species of Xenagama and Acanthocercus annectens from Horn of Africa are form two sister clades to Pseudotrapelus + Acanthocercus yemensis. Acanthocercus genus is polyphyletic. There is no genetic difference in nuclear sequences between Xenagama taylori and Xenagama wilmsi. In Pseudotrapelus there are two sister groups — Afro-Arabian P. sinaitus + African P. chlodnickii and Arabian — {[(Pseudotrapelus aqabensis + Pseudotrapelus jensvindumi) + Pseudotrapelus dhofarensis] + Pseudotrapelus sp.}. There is an mtDNA introgression from P. sinaitus to Pseudotrapelus sp. was found in the Al Mudawarra vicinity, south-eastern Jordan, where agamas with mt and nuclear DNA of P. sinaitus occur together with agamas with mtDNA of P. sinaitus and nuclear DNA of Pseudotrapelus sp.
