Unveiling the evolutionary history of a puzzling antlion genus Gatzara Navás (Neuroptera: Myrmeleontidae: Dendroleontinae) based on systematic revision, molecular phylogenetics, and biogeographic inference
<p>The antlion genus <em>Gatzara</em> Navás, 1915 is one of the major lineages of the subfamily Dendroleontinae Banks, 1899 (Neuroptera: Myrmeleontidae) from Asia, but having chaotic background of systematics. Here we present a comprehensive systematic revision and mitochondrial phylogenomic analysis to clarify the identity and to unravel the evolutionary history of this genus. Combining morphological and molecular evidence, we separate the species of <em>Gatzara</em> into two clades, and most of these species are transferred to the genus <em>Nepsalus</em> Navás, 1912 herein restored. The dated phylogeny with ancestral area reconstruction indicates that the common ancestor of <em>Gatzara</em> and <em>Nepsalus</em> might have been widely distributed in East Asia and these two genera might have diverged during the late Miocene. The speciation of most <em>Nepsalus</em> species that are allopatric in distribution might have been driven by a series of vicarience events related to the rise of the Himalayas and the formation of the major islands of East Asia during the late Miocene and Pliocene. A new species, namely <em>N. chikuni</em> sp. n., is described from Tibet. New taxonomic changes include the six new combinations: <em>N. caelestis</em> (Krivokhatsky, 1997) comb. n., <em>N. decorillus</em> (Yang, 1997) comb. n., <em>N. decorosus</em> (Yang, 1988) comb. n., <em>N. indicus</em> (Navás, 1914) comb. n., <em>N. insolitus</em> (Walker, 1860) comb. n., <em>N. jezoensis</em> (Okamoto, 1910) comb. n., and <em>N. petrophilus</em> (Miller & Stange, 1999) comb. n.</p>
