Sulcomesitius Moczar, 1970

Remarks.

This genus is characterized by the malar space as long as vertex-ocular line, convergent anteriorly, in front view, the anteromesoscutum with median mesonotal line well impressed, the forewing with nebulous Cu and A veins, the hypopygium with branches lobate and long, and the male genitalia with dorsal paramere S-shaped, ventral paramere narrower than dorsal ( Azevedo et al. 2018). However, it was found to be polyphyletic (Figs 4 - 6 ). The same applies to Sulcomesitius nepalensis , which was recovered as sister group to a clade formed by four species of Metrionotus and Brachymesitius krombeini in the partitioned Bayesian analysis and recovered nested within species of Metrionotus in the unpartitioned analysis; and Gerbekas laoensis , which was recovered as sister group to a clade formed by four species of Sulcomesitius in the partitioned Bayesian analysis and as single clade in the unpartitioned analysis. In both cases, the support for such groupings is low, indicated by posterior probability values below 0.4. To solve this problem, Sulcomesitius nepalensis Móczár, 1986 is herein transferred to Metrionotus , M. nepalensis ( Móczár, 1986) comb. nov. and Gerbekas laoensis Móczár, 1975 is herein transferred from Gerbekas to Sulcomesitius , S. laoensis ( Móczár, 1975) comb. nov.
