Species of the genera Acompomintho and Tricogena (Diptera: Calliphoridae: Rhinophorinae), and their phylogenetic position based on molecular and morphological data

Abstract: Acompomintho carmanica Ziegler sp. nov. from Iran and Acompomintho gavryushini Ziegler sp. nov. from Kazakhstan are described, illustrated and compared with the other known species of the genus. The male of Acompomintho sinensis (Villeneuve, 1936) is described and illustrated for the first time, and Acompomintho lobata Villeneuve, 1927 is re-described. The following new combinations are proposed: Tricogena caucasica (Villeneuve, 1908) comb. nov. [transferred from Acompomintho] and Tricogena grandiloba (Kugler, 1978) comb. nov. [transferred from Oplisa]. Tricogena caucasica and Tricogena rubricosa (Meigen, 1824) are re-described and illustrated. Keys to the species of Acompomintho and Tricogena are provided, and the delimitation of these genera is redefined. Additions to the key to the world genera of Rhinophorinae of Cerretti et al. (2020) are given, which allows identification of the redefined genera Acompomintho and Tricogena. The following new country records are also listed: Oplisa oldenbergi Herting, 1961 and Tricogena caucasica (Villeneuve, 1908) from Armenia, Oplisa nudiseta Zeegers, 2011, Paykullia nubilipennis (Loew, 1847), and Tromodesia vibripennis Rondani, 1862, from Greece, Acompomintho sinensis (Villeneuve, 1936), Stevenia fausti (Portschinsky, 1875), and Tricogena caucasica (Villeneuve, 1908) from Iran, and Tromodesia setiventris (Rohdendorf, 1935) from Kyrgyzstan. The phylogenetic relationships within the subfamily Rhinophorinae have been reconstructed. The results are based on BI and RAxML analyses. The Rhinophorinae appear with strong support as a monophyletic group, as do the two tribes Phytonini and Rhinophorini. All non-monotypic genera examined with more than one species included Acompomintho Villeneuve, 1927, Phyto Robineau-Desvoidy, 1830, Tromodesia Rondani, 1856, Paykullia Robineau-Desvoidy, 1830, Oplisa Rondani, 1862, Tricogena Rondani, 1856, and Stevenia Robineau-Desvoidy, 1830, proved to be monophyletic with strong support. The genera in question, Acompomintho and Tricogena, together with the genera Azaisia Villeneuve, 1939, Oplisa, Rhinomorinia Brauer & Bergenstamm, 1889, and Stevenia, come out in the Rhinophorini branch and are genetically and morphologically a very well-founded monophylum. The genus Acompomintho is probably a sister group of Stevenia, and the sister group of these two is Tricogena.
