Material examined. Holotype ♀; IRAN, Golestan province: Elburs 40 km S of Shahpasand Tilabad , 1600m, 16.vii.1977, leg. A.W. Ebmer / bei heraklionica spec.? Coll. Linsenmaier / GBIF _ Chr 00019822 ( NMLU).

Diagnosis. Chrysis crenulata sp. nov. belongs to the succincta group and is related to Chrysis heraklionica Linsenmaier, 1968 from Crete, as already noticed by Linsenmaier on his identification label. The main differences between these two species are body punctation, spaced in C. crenulata sp. nov., in particular well visible on mesonotum and metasoma ( vs. deep, dense, without polished interspaces in C. heraklionica ); scapal basin medially crenulate and not typically polished as in all the other species of the succincta group; impuncate area of scapal basin T-shaped, not largely polished as in other species ( Fig. 11B); colour pattern with scutellum green, contrasting mesoscutum ( Fig. 11C); green to golden-green on head, pronotum posteriorly, metanotum and propodeum (red non-contrasting and other segments blue in C. heraklionica ); antenna with scape, pedicel and first flagellomere basally metallic (non-metallic in C. heraklionica ).

Description. Holotype ♀ ( Fig. 11A–F). Body length 7.4 mm; anterior wing length 4.2 mm ( Fig. 11A).

Head. Vertex, ocellar area and brow with dense and small punctures (0.2–0.3× MOD); from posterior ocelli to temples with similar punctures but separated by polished wide interspaces of 1 puncture diameter; posterior ocelli with postero-lateral deep fovea confluent in a lateral, narrow fovea, as long as ocellus length; postero-laterad posterior ocelli with larger polished area as large as 1× MOD; scapal basin deep below upper margin, medially and apically relatively flat for females in this group; impunctate T-shaped area below upper margin and medially (width of 2× MOD) not fully polished, but unusually crenulated; laterally densely and finely punctate as in males of this group, each puncture bearing white short seta, but pilosity not covering face and malar spaces, still clearly visible; malar space finely and densely punctate; frontal carina weak ( Fig. 11B), irregular, barely visible as impunctate stripe between punctures, with darker coloration; genal carina sharp, straight, fully developed from middle eye to mandibular insertion; subantennal space short, 0.6× MOD; apex of clypeus straight, slightly arcuate upward with narrow, dark brown rim. Distance between anterior ocellus and margin of upper transverse frontal carina = 2.5× MOD. OOL 1.6× MOD; POL 2.0× MOD; MS 0.9× MOD; relative length of P:F1:F2:F3 = 1.0:1.7:0.8:0.7.

Mesosoma . Medial pronotal furrow deep, reaching 3/4 of pronotal length; pronotum with uneven punctures, small to medium sized (0.1–0.5× MOD), shallow on anterior margin, denser and deeper laterally, with occasional dots on interspaces; on mesoscutum with relatively shallow punctures, larger postero-medially on median area, distinctly smaller antero-medially ( Fig. 11C); median area with polished interspaces without small punctures or dots; lateral area of mesoscutum with denser punctures, in particular denser and deeper at sides; notauli formed by deep, blue metallic, round, and very small foveae, as large as the smaller adjacent punctures; parapsidal signum deep and distinct; scutellum with punctures similar to those at base of mesoscutum, with large triangular, polished area antero-medially; scutellar-metanotal suture deep, formed by longitudinally elongate foveae; metanotum densely and deeply punctate, with small punctures on narrow interspaces; posterior propodeal projections subparallel; mesopleuron with episternal sulcus formed by large, subrectangular foveae, as large as two punctures and confluent with adjacent points ( Fig. 11D).

Metasoma. Punctures on terga even, deep without dots or small punctures on interspaces; longitudinal median carina faint; third tergum with large, deep pits of pit row, two median pits larger than other punctures on tergum, others as large or slightly larger than largest punctures on tergum ( Fig. 11E); apical margin quadridentate, with median ones closer each other than lateral and median one; median teeth blunt, lateral ones acute; black spots on second sternum large, covering half of sternum length; spots fused only medially with posterior margin convex ( Fig. 11F).

Colouration. Body with typical colour pattern of succincta , with pronotum anteriorly, mesoscutum and metasoma red, excluding the apical margin blue; head and other parts green to golden green; legs greenish to reddish; black on median area of metascutum and antero-medially on second tergum; tegula non-metallic; scape, pedicel, and first flagellomere basally metallic.

Vestiture. Setae whitish and long (at least 1.5× MOD) on head and mesosoma dorsally; longer (up to 3× MOD) on metasoma laterally and on femora and tibiae, here erect on both and outer side.

Male. Unknown.

Etymology. The specific epithet crenulata derives from the New Latin adjective crenulatus (crenulate) and refers to the microsculpture on the scapal basin of the female, usually polished in the succincta species-group.

Distribution. * Iran ( Golestan).
