    Abstract

    Variation among complete cytb sequences (1140 bp) of Aphanius mesopotamicus Coad, 2009 was compared with closely
    related species, to investigate the validity of this taxon as a newly-described tooth-carp based on morphological characteristics.
    Maximum likelihood and Bayesian likelihood trees supported the monophyly of A. mesopotamicus and its sister
    group relationship to A. sophiae. Some 10–16 differences were found when compared to four different population samples
    of A. sophiae, whereas, intraspecific differences were only up to 6 bp. These distances suggest divergence from a common
    ancestor with A. sophiae at roughly 1 million years ago. These results are congruent with morphology-based hypotheses,
    indicating a recent speciation event.

     

    The recent Aphanius-frenzy continues. Would love a copy of this!
