Material examined. Holotype ♀; IRAN, Mazandaran province: 75 km S of Chalus [ Elburs], 2400m, 12.vii.1977, leg. J. Gusenleitner ( NMLU).

Diagnosis. Chrysis chamrosh sp. nov. belongs to the succincta group. It is closely related to the Central

Asian Chrysis irenes Semenov-Tian-Shanskij & Nikol’skaya, 1954, known from Tajikistan, whose type is illustrated in Rosa et al. (2017a, plate 67). Chrysis chamrosh sp. nov. can be separated by its colour pattern, an important diagnostic character in this species group ( Linsenmaier, 1959a; Rosa & Makris, 2023), by the shape of the apical margin of the third tergum, the pit row and the body punctation. The body colour is green with red to purplish areas on anterior margin of pronotum, mesonotum, metanotum and propodeum ( Fig. 10A) ( vs. red only on mesonotum, with a small golden hue anteromedially on scutellum in C. irenes ); the scapal basin is largely polished ( Fig. 10B) ( vs. densely micropunctate laterally); the mesonotal punctation is spaced and shallow ( Fig. 10C) ( vs. dense and deeper); the metasomal punctation is distinctly shallower and sparser in the second half of the tergite ( vs. uniformly dense); the third tergum has small, shallow and spaced pits of the pit row ( Fig. 10E) ( vs. pits of the pit row deep and elongate); the black spots on second sternum are fused medially in both species, but in C. chamrosh there is a greenish median spot before the apical margin ( Fig. 10F).

Description. Holotype ♀ ( Fig. 10A–F). Body length: 6.3 mm; wing length: 3.8 mm.

Head. Frons with dense, weakly impressed, small punctures (0.2–0.4 MOD), larger and more spaced on temples between lateral ocelli and eyes, denser and smaller on ocelli area and occipital area; lateral ocelli with two deep lateral foveae; frontal carina weak, as a dark line with vaguely M-shaped between frontal punctures ( Fig. 10B); punctures between scapal basin and frontal carina larger than on those between anterior ocellus and frontal carina, not elongate; scapal basin deep, impunctate and polished medially with scattered, small punctures laterally ( Fig. 10B); malar space long (1.1.MOD) covered by small, dense punctation; subantennal space short (0.6 × MOD); genal carina sharp, fully developed from temple to mandible insertion; apex of clypeus with thin brown rim. OOL 1.8 × MOD; POL 2.0 × MOD; MS 1.1 × MOD; relative length of P: F1: F2: F3 = 1.0: 1.6: 1.0: 0.8.

Mesosoma . Medial pronotal line weak, reaching 1/3rds of pronotal length; pronotum as long as scutellum, with small to medium punctures (0.1 – 0.6 × MOD), the latter larger than punctures of head; punctures on pronotal scutum weak and irregularly shaped; mesoscutum with similar puncture, sparser and weaker on median area and between notauli and parapsidal lines, with wide polished interspaces; notauli formed by small, deep foveae, subrectangular basesally and small and rounded towards apex, parapsidal signum as deep, dark line; mesoscutellum with spaced and shallow punctures; scutellar-metanotal suture deep, formed by longitudinally elongate foveae; metanotal punctures denser, without polished interspaces; posterior propodeal projections slightly divergent; with blunt apex; mesopleuron with punctures larger and shallower on mesepimeron; episternal sulcus formed by small, subsquare foveae, partially confluent each other.

Metasoma. Terga with even, geminate punctures (punctures appearing as two merged together, as the typical metasomal sculpture of Trichrysis Lichtenstein, 1876 ), smaller than those on mesoscutum; on first tergum slightly larger, on second tergum smaller and sparser on second half; on third tergum sparser; median longitudinal carina faint; pits of the pit row small, black and rounded ( Fig. 10E); apical teeth short, triangular, bordered with hyaline rim; black spots on second sternum fused medially, covering almost 2/3 rd of sternal length and with greenish median spot before the apical margin ( Fig. 10F).

Colour. Head and mesosoma green with red to purplish areas on anterior and lateral margin of pronotum, mesonotum, metanotum and propodeum; tegula slightly metallic red along inner margin; notauli blue; scutellar-metanotal suture blue to green; mesopleuron green with golden hue medially; legs pinkish; metasoma red to purplish with apical margin of all tergites green; sterna red; wings hyaline with brown nervures.

Male. Unknown.

Etymology. The specific epithet chamrosh (masculine, in apposition) is the name of a mythological bird in Persian mythology said to live on the summit of Mount Alborz, close to the type locality area where the holotype of this Chrysis species was collected, in Mazandaran Province.

Distribution. Iran ( Mazandaran).
