|Chamaesphecia montis (Leech, 1889)|
in Yata, Gorbunov, Aoki & Naoki, 2018.
The systematic position of Aegeria montis Leech, 1889 and Zhuosesia zhuoxiana Yang, 1977 is discussed. Having studied newly collected material, we transfer A. montis to the genus Chamaesphecia Spuler, 1910, subgenus Chamaesphecia s. str. The male of this species and its genitalia are illustrated for the first time. The host-plant of its larvae is assumed to be a species of Euphorbia (Euphorbiaceae).
Zhuosesia Yang, 1977, syn. nov., is shown to be a junior subjective synonym of Chamaesphecia Spuler, 1910 with the new combination of its type species, Chamaesphecia zhuoxiana (Yang, 1977), comb. nov.
