However, Zlobin (1995) considered color characteristics of the abdomen unstable and unreliable for identification of the two species according to those specimens from the East Palaearctic, but the subsequent researchers still used the color characteristics of the abdomen for separating the two species (Papp and Černý 2017; Warrington and Perry 2020). Contrary to morphological classification, the host preferences of two species are clearly distinct. The host plants of M. scutellata are Carex spp. ( Cyperaceae), which are widely distributed in temperate and wetland globally. The sampling habitat supports four Carex species: Carex angarae Steud., C. meyeriana Kunth, C. pediformis C. A. Mey. and C. korshinskyi Kom. The host plant of M. junci is Juncus gerardii Loisel. ( Juncaceae) in von Tschirnhaus (1981), as the statement by Warrington and Perry (2020) reported “ M. junci is known to utilize Juncus, chiefly J. gerardii Loisel., saltmarsh rush ”. The sampling locality also harbors four Juncus species: Juncus bufonius L., J. gracillimus (Buchenau) V. I. Krecz. &amp; Gontsch., J. papillosus Franch. &amp; Sav., and J. turczaninowii (Buch.) V. I. Krecz. Unfortunately, our specimens were only collected with Malaise traps and not directly collected from the host plants.</p><p>The Maximum-Likelihood and Neighbor-Joining phylogenetic trees (Figs 7, 8) show that the species M. scutellata consists of two clades, one from the Palaearctic Region (China, Finland, Montenegro) and another from the Nearctic Region. Although M. junci is clustered with the Palaearctic clade of M. scutellata, it is first clustered with M. nigriorbita (Hendel, 1931) as a single clade.</p><p>The newly examined specimen of M. scutellata (accession number PZ 742162) from Inner Mongolia, China — characterized by a predominantly brown abdomen and tergites 2–4 with broad lateral yellow markings — is nested within the Palaearctic clade of M. scutellata . Moreover, our generated sequence shares up to 98 % identity following alignment with publicly available M. scutellata sequences. Based on the above analysis, it is confirmed that our specimens belong to M. scutellata, but this does not prove that M. scutellata and M. junci are conspecific.</p></div>	https://treatment.plazi.org/id/DB8F70A73FDD528BBF55867DD5A6C1B1	Public Domain	No known copyright restrictions apply.
