Species of Artemiaare regionally endemic branchiopod crustaceans composed of sexual species and parthenogenetic lineages, and represent an excellent model for studying adaptation and speciation to extreme and heterogeneous hypersaline environments. We tested hypotheses of whether populations from the Tibetan Plateau belong to A. tibetianaAbatzopoulos, Zhang & Sorgeloos,1998and whether a population from Kazakhstan is a new species, using other Asian species of Artemiaas outgroups. We conducted a multitrait phylogenetic study based on the complete mitogenome, mitochondrial (COI, 12S, 16S) and nuclear (microsatellites, ITS1) markers, and a suit of uni- and multivariate morphological traits. Our results led to the discovery of two new species, one from the Tibetan Plateau (Haiyan Lake) in China (Artemia sorgeloosin. sp.) and a second from Kazakhstan (Artemia amatin. sp.). Our analysis demonstrate that A. tibetianaand A. amatin. sp.are monophyletic, whereas A. sorgeloosin. sp., and A. tibetianaare polyphyletic. Evolutionary relationships based on mitochondrial and nSSR markers suggest that A. tibetianamay have arisen from a past hybridization event of a maternal ancestor of A. tibetianawith A. sorgeloosin. sp.or its ancestor. We present the complete mitogenome of A. tibetiana, A. amatin. sp., and A. sorgeloosin. sp.We also provide a novel taxonomic identification key based on morphology, emphasizing the phenotype as a necessary component of the species concept. |
