Material examined. Holotype ♂; IRAN, Kerman province: N of Deh Bakri , 29°07'40"N, 57°55'99"E, 1825m, 26–27.v.2012, leg. D. Baiocchi ( MSNM).

Diagnosis. Chrysis edentata sp. nov. belongs to the succincta group and is somehow related to Chrysis mavromoustakisi Trautmann, 1929 from Cyprus due to the general habitus, similar to Chrysis grohmanni Dahlbom, 1854 and without apical teeth on the last visible tergum. Also the short second flagellomere (shorter than the third) and male genitalia are related to C. mavromoustakisi , but the genital capsule of C. edentata is narrower, the gonostylus shorter and the apex of gonostylus simple, digitate, not bifurcate as in C. mavromoustakisi ( Figs 16A, B); apical margin of third tergum edentate, unmodified ( Fig. 15E), whereas in C. mavromoustakisi is pulled out, with elongate pits of the pit row ( Fig. 16G); black spots on second tergum medially fused in C. edentata , with straight margin, covering less than half sternum (vs. separate medially, with oblique margin and covering more than half sternum); besides other characters, also the colour pattern of Chrysis edentata sp. nov. is significantly different, being entirely green ( Fig. 15A) and clearly distinct from the contrasting red and blue colour of Chrysis mavromoustakisi ( Figs 16G, compare also the picture in Rosa et al., 2017d:fig. 7B).

Description. Holotype ♂ ( Figs 15A–F). Body length 6.3 mm; anterior wing length 3.5 mm ( Fig. 15A).

Head. Vertex, ocellar area and brow between anterior ocellus and upper branch of transverse frontal carina with dense and small punctures; postero-laterad posterior ocelli with polished area as large as 1× MOD; posterior ocelli with postero-lateral deep and small fovea ( Fig. 15C); scapal basin deep and medially polished for a width of 1× MOD, laterally densely and finely punctate, each puncture bearing white seta; white pilosity covering face and malar spaces ( Fig. 15B); malar space finely and densely punctate; frontal carina double, upper transverse frontal carina substraight, slightly curved downwards medially, downcurved to connect lower part laterally ( Fig. 15B); lower carina toping scapal basin and weakly produced, compared to upper one; genal carina sharp, straight, fully developed from middle eye to mandibular insertion; subantennal space short, 0.6× MOD; apex of clypeus arcuate upward with narrow, dark brown rim. Clypeus sparsely micropunctate with white setae laterally. Distance between anterior ocellus and upper margin of frontal carina 1.2× MOD; distance between anterior ocellus and upper margin of scapal basin = 2.0× MOD. OOL 2.0× MOD; POL 2.1× MOD; MS 1.0× MOD; relative length of P:F1:F2:F3 = 1.0:1.0:0.7:1.2.

Mesosoma . Medial pronotal furrow deep, narrow, reaching half of pronotal length; pronotum with dense, deep and even punctures of medium size (0.5× MOD), with occasional small punctures between punctures; row of smaller punctures along posterior margin; punctation on mesoscutum and scutellum deep, with larger punctures (up to 0.8× MOD) postero-medially, spaced medially on mesoscutum, with polished interspaces ( Fig. 15C); punctation on lateral areas of mesoscutum denser; notauli formed by deep, black, round, and small foveae, as large as half of larger punctures on mesonotum; parapsidal signum deep and distinct; punctures on scutellum denser with polished area along posterior margin; scutellar-metanotal suture deep, with large, irregular median fovea; posterior propodeal projections pointed, divergent, with lateral sides slightly concave; mesopleuron with episternal sulcus formed by large, irregular foveae, as large as two or three punctures and confluent with adjacent points ( Fig. 15D).

Metasoma. Punctures on terga dense, deep and slightly smaller than those on metanotum, with dots on interspaces; punctures becoming smaller towards apical margin; longitudinal median carina weak and barely visible at base of second tergum ( Fig. 15E); third tergum with small, deep pits of pit row; apical margin sinuous, with a lateral concavity before weak median indentation; margin bordered by narrow but distinct hyaline rim; black spots on second sternum relatively small, covering less than first half of sternum length; spots medially fused with posterior margin straight ( Fig. 15F); genital capsule narrow, elongate, with simple gonostylus, digitate distally, not bifurcate ( Fig. 16A).

Colouration. Body entirely emerald green including tegulae, legs, scape, pedicel, first and second flagellomere.

Vestiture. Setae whitish and long (at least 2× MOD) on head and mesosoma dorsally, on metasoma laterally; on femora; on tibia long and erect only on outer side.

Female. Unknown.

Etymology. The specific epithet edentata derives from the Latin adjective edentatus (toothless) and refers to the simple apical margin of the last metasomal tergum without teeth.

Distribution. * Iran (Kerman).
