Brachyiulini incertae sedis: "Lohmander (1936) erected Armeniobrachyiulus, a monotypic subgenus of Megaphyllum (=Chromatoiulus auct.), to incorporate this species. The author presented no diagnosis for Armeniobrachyiulus, but he pointed out several gonopodal characteristics of M. sevangense he found sufficiently unusual to create the new subgenus. He also suggested close similarity to the subgenus Omobrachyiulus (here elevated to full genus) of Megaphyllum. Considering the description and drawings of M. sevangense (in Lohmander 1932 & 1936), this looks plausible, especially if the basal protrusion on the anterior side of the opisthomerite in M. sevangense can be regarded as homologous to the better developed mesomeroidal lobe in members of Omobrachyiulus. Examination of females is of key significance for clarifying the systematic position of the species. Revealing the vulval characters would either support or refute its assignment to Megaphyllum."
