Euchroeus purpuratus (Fabricius, 1787)

Chrysis purpurata Fabricius, 1787: 283. Neotype ♀ (designated by Pavesi & Strumia 1997: 195); France (Turin) (examined).

Material examined.

Mongolia: Dornod, 2 ♂♂, 20 km W of Choibalsan , 48°01'N; 114°14'E, 800 m alt., 24.VII.2007, leg. MH (MHC) ; Khentii, 1 ♂, 100 km NE of Ondorkhaan, Kerulen River , 970 m alt., 22.VII.2007, leg. JH ( PRC) ; Sukhbaatar , 1 ♂, 100 km SSW of Baruun-Urt, 1100 m alt., 30.VII.2007, leg. MH ( PRC) .

Remarks.

The Mongolian population of Euchroeus purpuratus is clearly separated from the western form by different punctation of clypeus, with small punctures and polished interspaces without micropunctation (vs. denser punctures, micropunctate on interspaces); elongate, spiniform process on propleuron and antero-ventrally on mesopleuron; metasoma mostly without darker bands. Future barcoding analysis will clarify the affinities between the western and Mongolian populations. Interestingly, another Mongolian species close to the genus Euchroeus , namely Spinolia spinosa Rosa & Halada in Rosa et al. 2020, shares similar spines on propleuron.

Distribution.

*Mongolia (Dornod, Khentii, Sukhbaatar); West-Palaearctic from Western Europe to Central Asia ( Rosa et al. 2019).
