6A4514BB3CDC5A7B9FA6B2CAEF273BB2.taxon	diagnosis	Diagnosis. Chrysis arkadyi sp. nov. is recognised by the following characters: body blue with light blue and greenish reflections (Fig. 1), with black median area of mesoscutum, and with wide green bands laterally and posteriorly on terga I-II; metapostnotum T-like, reduced to a small median area, with punctures smaller than those on metascutellum; metasoma with terga I-II extremely elongated compared to other species in the Chrysis splendidula species group; tergum III with polished and elongate post pit row area; black spots on sternum II elongate and sub-ovoid. This new species can be distinguished from other blue coloured Central Asian species of the same species group by reduced metapostnotum, elongated metasomal terga and elongate post pit row area. This species is more closely related to Chrysis nohirai Tsuneki, for the elongate shape of metasomal tergum II (type examination based on pictures taken by T. Mita). However, C. arkadyi sp. nov. is easily distinguished by: transverse frontal carina M-shaped; dense body punctation, in particular on mesonotum, mesopleuron and second tergum; structure of metasomal tergum I elongate, 0.6 x as long as length of tergum II and structure of tergum III with post pit row distinctly elongate (1.5 MOD) (vs. transverse frontal carina medially straight and laterally downcurved; body sparsely punctate, with wide impunctate interspaces on lateral areas of mesoscutum, mesopleuron and second tergum, and unmodified structure of tergum I, 0.4 x as long as length of tergum II and of tergum III, with post pit row not distinctly elongate (1.0 MOD) in C. nohirai).	en	Rosa, Paolo, Baiocchi, Daniele, Halada, Marek, Proshchalykin, Maxim Yu.

Median area of mesoscutum in posterior half with larger punctures and broader polished intervals; lateral areas of mesoscutum with irregularly sized punctures and corrugated interspaces; parapsidal furrow distinctly engraved; notauli as line of sub-square pits, decreasing towards anterior margin of mesoscutum. Mesoscutellum with larger punctures and broad, polished interspaces, locally with tiny punctures; laterally with smaller, dense punctures along metanotal trough. Metanotum slightly convex, with large, polygonal and uneven punctures; anterior margin of metanotum with large impunctate and depressed median area. Mesopleuron almost without trace of episternal sulcus, with large punctures and densely, minutely punctate intervals; scrobal sulcus as deep, polished line (Fig. 1 A); metapostnotum reduced, triangular, T-shaped, with small punctures and with two largely expanded lateral areas, with raised transverse carinae; posterior propodeal projections laterally expanded and downward directed, with basal margin slightly concave. Metasoma. Metasoma densely punctate; puncture diameter about 1 / 2 to 1 / 3 of largest punctures on mesoscutellum; metasomal terga elongate (Fig. 1 C-F), tergum I 0.6 x as long as length of tergum II; tergum III slightly longer than tergum I; tergum II with weak median ridge; pit row of tergum III deep, with elongated, large pits; post pit row distinctly elongate (1.5 MOD); apex of T 3 with four short, triangular teeth; intervals between median and lateral teeth almost equal; black spots on sternum II sub-ovoid, narrow and connected to lateral margins, widely separated medially (Fig. 1 F). Colouration. Body blue to deep blue, almost black on ocellar area, median area of mesoscutum and basally on metasomal tergum II; green on scape, pedicel, first flagellomere, postero-laterally on terga I-II, on tergum III pre pit row, and on sternites (Fig. 1 C-F); other flagellomeres black; tegula light blue; post-tegula bright metallic blue; forewing slightly infuscate, with darkened radial cell.

BDCB6217F04A5089B27DBA654FD7527E.taxon	diagnosis	Diagnosis. The Chrysis splendidula species group includes Palaearctic species recognizable by the last metasomal tergum which is coloured blue or green, usually contrasting with metasomal terga I-II which are red. However, exceptions to this colouration pattern are five Central Asian species with terga I-II blue or blue with green to light blue stripes (Chrysis centralis Semenov-Tian-Shanskij, 1967; C. circassica Mocsary, 1893; C. hyacinthus Semenov-Tian-Shanskij, 1967; C. kokandica Radoszkowsky, 1877; C. serpentula Semenov-Tian-Shanskij, 1967) and a Japanese one (C. nohirai Tsuneki, 1952). Members of the Chrysis splendidula species group can be recognised by the combination of the following characters: transverse frontal carina distinct and raised; apical margin of metasomal tergum III with four sharp teeth, and black spots on sternum II elongate, connected to lateroterga and widely separated in the middle (Fig. 1 F).	en	Rosa, Paolo, Baiocchi, Daniele, Halada, Marek, Proshchalykin, Maxim Yu.

Face with distinct and raised transverse frontal carina, M-like or biconvex, recurved below; scapal basin medially polished to finely wrinkled; malar spaces usually 1.0 - 1.5 x MOD; second flagellomere usually slightly shortened; carina on metasomal tergum II indistinct or as an impunctate line, rarely raised and sharp; tergum III with distinct row of small, round to slightly elongate pits; apical margin of tergum III with four sharp, triangular teeth; black spots on sternum II widely separated and elongate, adjacent to lateral margin.	en	Rosa, Paolo, Baiocchi, Daniele, Halada, Marek, Proshchalykin, Maxim Yu.

95288B6C335B572193FC1394220914D3.taxon	diagnosis	Diagnosis. The Chrysis succincta species group includes more than a hundred species distributed worldwide, with a large majority known in the Palaearctic region, and subdivided into Chrysis succincta s. str. subgroup and leachii subgroup (or leachii group according to Linsenmaier 1959). Usually, Palaearctic species are easily recognised by their slender habitus and by their peculiar colouration, with the body largely red coloured. The most diagnostic feature is anyhow the prominent brow, often ridge-like, and the transverse frontal carina which is usually only partially developed; females scapal basin is always polished medially in the Chrysis succincta s. str. subgroup, whereas it is finely striated in the leachii subgroup, while in males it is finely punctate in both subgroups. The apical margin of tergum III is highly variable, bearing from none to four teeth or two median teeth almost fused together and projecting medially.	en	Rosa, Paolo, Baiocchi, Daniele, Halada, Marek, Proshchalykin, Maxim Yu.
