Syrphoctonus rhysus ( Momoi, 1973)

Two females from the same locality match the description of the holotype, one is here designated as lectotype.

Type material. Lectotype: Mongolia - Central aimak, Tosgoni ovoo, 5–10 km N from Ulan-Baator, 1500– 1700 m, 19–20., 23–24. 0 7.1967. Labelling of the lectotype: MONGOLIA: Central aimak; Tosgoni ovoo, 5–10 km N; von Ulan-Baator, 1500–1700 m; Exp.Dr.Z.KASZAB, 1967 // Nr. 926; 19–20., 23–24.; VII. 1967 // Homotropus ; rhysus ; Det. S. MOMOI,`// Lectotypus; Homotropus Ψ; rhysus Momoi ; label: S.Klopfstein '06. Paralectotype: 1 Ψ from the same locality (all HNHM).

Diagnosis. This species belongs to the pictus -group of Syrphoctonus , and is like S. liparus very close to S. pictus and S. megaspis . Characters that distinguish it from these two species are the darkened front coxae, the more intensely striated second tergite and the more strongly coriaceous mesopleurae.
