Diagnosis. Chrysis storozhenkoi sp. nov. belongs to the maculicornis group. Due to its unusual colour pattern ( Figs 5A, C, E View FIGURE 5 ), it may be confused with Chrysis kizilkumiana Rosa, 2015 ( Figs 5B, D, F View FIGURE 5 ), also described from Uzbekistan. However, C. kizilkumiana belongs to the C. cerastes group and the two species can be easily separated by the following characters: flagellomeres light brown dorsally in C. storozhenkoi ( Fig. 5A View FIGURE 5 ) ( vs black in C. kizilkumiana , Fig. 5B View FIGURE 5 ); transverse M-shaped frontal carina in C. storozhenkoi ( Fig. 5A View FIGURE 5 ) ( vs inverted U-shaped in C. kizilkumiana , Fig.5 B View FIGURE 5 ); the differently shaped and coloured apical margin of the third tergum, which is blue, contrasting in colour with the rest of the third tergum and with spiny or acute teeth in C. storozhenkoi ( Fig. 5E View FIGURE 5 ) ( vs concolours and with short teeth in C. kizilkumiana , Fig. 5F View FIGURE 5 ), and for the short genital capsule, with short aedeagus and gonostyle, as in species of C. distincta subgroup in C. storozhenkoi ( Fig. 6D View FIGURE 6 ) ( vs elongate genital capsule, with long aedeagus and gonostyle, similar to C. cerastes Abeille de Perrin, 1877 and C. mutabilis du Buysson, 1887 in C. kizilkumiana , Fig. 6E View FIGURE 6 ). Compared to other Central Asian species of the maculicornis group, C. storozhenkoi sp. nov. can be distinguished by its unique colour pattern: first tergum and anterior part of the second tergum green fading into golden and red in the posterior half, third tergum flame red with blue apical margin ( Fig. 5B View FIGURE 5 ). It also differs by having antennae with light brown flagellomeres F2–F11 (F2 brown in C. speciosa and all brown to black in some species such as C. svetlana ), and unusual long hairs on first and second flagellomere ( Fig. 6A View FIGURE 6 ) (unmodified in other species); the third tergum has small pits in the pit row and short teeth, with a particular narrow postero-pit row area ( vs large pits and elongate post-pit row area in C. speciosa ).

Description. Holotype ♂. Body length 6.9 mm; anterior wing length 4.2 mm;

Head. Vertex and ocellar area with dense and small punctures (0.2–0.3× MOD); frontal carina strong, raised, M-shaped ( Fig. 5A View FIGURE 5 ); frons largely polished below frontal carina to scapal basin; scapal basin deep below upper margin, medially and apically, close to clypeus, impunctate, fully polished; laterally densely and finely punctate, each puncture bearing white short seta; pilosity partially covering side of face and malar space; malar space finely and densely punctate; genal carina sharp, fully developed from middle eye to mandibular insertion; subantennal space 0.9× MOD; apex of clypeus straight, slightly arcuate upward with narrow, dark brown rim; posterior ocelli with lateral deep fovea, as long as ocellus length; postero-laterad posterior ocelli with larger polished area as large as 1× MOD. Narrow distance between anterior ocellus and margin of upper transverse frontal carina = 0.5× MOD. Subantennal distance: 0.8× MOD. OOL 1.4× MOD; POL 2.3× MOD; MS 0.9× MOD; relative length of P:F1:F2:F3 = 1.0:0.9:0.7:1.2. The type is damaged and lacks the right flagellomeres F3–F11.

Mesosoma. Medial pronotal furrow shallow, undefined, reaching half pronotal length ( Fig. 5C View FIGURE 5 ); pronotum with double punctures, small to medium sized (0.1–0.5× MOD), evenly sparse medially, denser and deeper laterally, with dots on interspaces; on mesoscutum with even and relatively sparse punctures, with polished and shining interspaces (1–2 PD) without small punctures or dots between punctures; lateral area of mesoscutum with denser punctures around tegula; notauli formed by deep, blue metallic pits, subsquare basally, and rounded apically, as large as larger punctures basally and decreasing in size apically ( Fig. 5C View FIGURE 5 ); parapsidal signum deep and distinct; scutellum with punctures similar to those at base of mesoscutum, but more spaced medially, with wide polished anteromedian area; scutellar-metanotal suture deep, formed by longitudinally elongate foveae, with large fovea medially; metanotum densely and deeply punctate, with round punctures separate by polished, narrow interspaces; posterior propodeal projections slightly divergent; mesopleuron with episternal sulcus formed by large, subconfluent foveae, as large as one to two punctures, not confluent with adjacent points.

Metasoma. Punctures on terga even, deep, with sparse dots or small punctures on interspaces; longitudinal median carina sharp on second tergum ( Fig. 5E View FIGURE 5 ); third tergum with small, round and shallow pits of pit row, median pits as large as other punctures on tergum, lateral pits larger and deeper ( Fig. 5E View FIGURE 5 ); apical margin quadridentate, with sharp teeth; interval between median teeth subequal to interval between median and lateral tooth ( Fig. 6B View FIGURE 6 ); black spots on second sternum small, suboval, covering 2/5 of sternum length; spots medially separated by narrow metallic line, 0.5× MOD ( Fig. 6C View FIGURE 6 ). Genital capsule similar to other species of the maculicornis group, without distinctive features ( Fig. 6D View FIGURE 6 ).

Colouration. Head, mesosoma, first tergum and basal part of second tergum green, rest of second tergum golden to red; third tergum red to flame red or violet, apical margin contrasting blue; legs greenish, tarsi brownish; tegula metallic green; scape and pedicel green, and first flagellomere dark brown, apically light brown; other flagellomeres light brown ventrally and largely dark brown dorsally, light brown basally.

Vestiture. Setae whitish and short (at least 1.0× MOD) on head and mesosoma dorsally; slightly longer (up to 1.5× MOD) on metasoma posteriorly. First two flagellomeres with unusual, whitish setae ( Fig. 6A View FIGURE 6 ).

Female. Unknown.

Etymology. The specific epithet storozhenkoi is dedicated to the entomologist Prof. Dr. Sci. Sergey Yurievich Storozhenko (Vladivostok, Russia) in recognition of his professional work. As Chief Editor of the journal Far Eastern Entomologist, he contributed to the study and publications of the first author on Russian Chrysididae .

Distribution. Uzbekistan.
