Holotype ♀; Mongolia: Kobden (Khovd) (ISEA-PAS) (examined) ( comparata group). Mocsary 1889 : 426 (cat., descr., Mongolia). Chrysis mocsaryi : Dalla Torre 1892 : 78 (cat., Mongolia); Kimsey and Bohart 1991: 440 (cat., Mongolia: Kobden, comparata- Chrysis scutellaris group); Rosa et al. 2015 : 41 (cat., type series), 42 (fig. 4); 2020: 66 (cat.). Material examined. Mongolia : Khovd , 1 ♂ , 20 km SE of Altaj , Elkhon , 26.VII.1970 , leg. M. Kozlov (ZIN) . Diagnosis. Male (hitherto unknown). Body length 6.7 mm. Head . Transverse frontal carina raised, with two lateral branches encircling the anterior ocellus (Fig. 2A and B ); punctation in this area shallow to undefined; F1 as long as F2 and slightly metallic only basally; subantennal spaces elongate, 1.3 x MOD. Mesosoma . Anteromedial pronotal area widely depressed and anteromedian line indistinct (Fig. 2B ); pronotum and mesonotum with even punctures, larger on the latter and polished interspaces; notauli as narrow, deep line; posterior propodeal projections narrow, apically acute and slightly divergent; mesopleuron with scrobal sulcus formed by wide, triangular and impunctate area; episternal sulcus deep and fully developed (Fig. 2D ); fore wing with radial sector almost reaching wing margin; tarsi light yellow, meso- and meta-basitarsus whitish. Metasoma . Terga with dense punctures and polished interspaces (Fig. 2F ); T1 dorsally, T2-T3 apicolaterally greenish to golden-greenish (possibly red in nature), contrasting with dark blue to black anteromedian area; apical margin of T3 blue after pit row; pits of pit row small, deep and rounded; apical margin quadridentate, with short, acute teeth (Fig. 2E ); interval between median teeth slightly wider than interval between median and lateral tooth; metasomal longitudinal carina faint; black spots on S2 small, subrectangular, medially largely separated (Fig. 2G ); genital capsule similar in structure to other species of the C. scutellaris group. Figure 2. Chrysis mocsaryi Radoszkowski, male A head, frontal view B habitus, dorsal view C genital capsule D habitus, lateral view E metasoma, posterior view F metasoma, postero-lateral view G metasoma, ventral view. Scale bars: 1 mm. Distribution. Mongolia (Khovd) (Radoszkowski 1889). Remarks. The specimen examined (Fig. 2A-G ) belongs to the Chrysis scutellaris species group and it is here considered as the unknown male of Chrysis mocsaryi , based on the unusual metasomal colouration, similar to that of the female. Examination of more material is anyway needed to confirm this identification.
