SPECIMENS EXAMINED. Holotype – ♀, Iran: Elburs, 50 km S Chalus ,

2800m, 26.VII 1977, leg. J. Gusenleitner, GBIF _ Chr 00018953 [ NMLS]. Paratypes :

Iran: 1♀, same collecting data of holotype [PRC]; Turkmenistan: 5 km N of Kara-

Kala, Tarkhaj canyon, 2.V 1991 , 1♀, leg. V. Kazenas [ZIN].

DIAGNOSIS. Chrysis gertiana sp. n. is a remarkable species, whose insertion in a species group without examination of the male is uncertain; I here consider its placement as provisional. For the edentate shape of the apical margin it may be related to C. curta, C. millenaris, C. phryne or C. rubricata species groups.

Nevertheless, from all these groups it is separated by the short malar spaces and the ill-defined black spots on second metasomal tergum; from the first two groups also by well outlined TFC and large dimensions. It is recognizable for the coloration and the large and triangular mesoscutal antero-lateral corners over mesoscutal trough.

DESCRIPTION. Body length 6.9 mm. Fore wing length 4.5 mm. Female. OOL

= 1.9 MOD; POL = 1.9 MOD; MS = 1.0 MOD; relative length of P:F1:F2:F3 = 1.0:

1.5:0.8:0.7.

Head. In full face view, length 1.6 mm, width 2.0 mm. Apex of clypeus medially markedly notched at obtuse angle, bordered by a thick rim (0.5 MOD); TFC well-

marked, M-shaped; scapal basin hollowed, medially transversely striate, laterally with dense, tiny punctures, covered by short, appressed, silvery setae. Malar space

1.0 MOD, as long as 1/5 of F1. Genal carina fully developed up to mandibular joint.

Subantennal distance about 1 MOD. Ocelli not lidded.

Mesosoma. Length 2.6 mm; width (PPW) 1.8 mm. Pronotum anteromedially with deep groove exceeding half pronotal length; punctation double, with small and medium-sized punctures (0.4 MOD). Mesoscutum with similar punctures, denser and subreticulate; notauli complete and parapsidal lines incomplete, hardly visible.

Mesoscutellum with larger punctures (up to 0.5 MOD), with shining interstices and small to very small punctures among larger punctures; mesoscutal antero-lateral corners over axillary trough large and triangular. Metascutellum with denser and larger punctures. Mesopleuron with dense and irregular punctures; episternal sulcus hardly recognizable only above for 3–4 aligned larger and foveate punctures. Propodeal teeth diverging and pointing backwards.

Metasoma. Length 3.0 mm. Punctation on first tergum with small and scattered punctures, denser along posterior margin, with copious small punctures on interstices.

Second tergum with smaller, deep, geminate punctures, transversally subcontiguous on the anterior half, smaller and scattered on the posterior one, in the middle of the latter almost impunctate, only with minute dots; laterally with tiny punctures on interstices.

dorsal view; 34 – habitus, lateral view; 35 – head, frontal view; 36 – metasoma, dorso-lateral view. Scale bar = 1.0 mm.

Third tergum with irregular punctation; apical margin smooth, edentate; pits of the pit row deep, elongate; post pit row area narrow. Black spots on the second sternum ill-defined and small.

Coloration. Body golden-green; bluish on ocelli area and occiput, median lobe of mesoscutum, sutures and axillary trough, and posterior edge of third metasomal tergum; metasoma pinky red to coppery, first tergum distinctly more green. Body ventrally dark green. Mandibles brown, medially lighter, with metallic green reflections at base. Scape, pedicel and F1 basally metallic green, flagellum black. Legs green with brown tarsi. Tegulae metallic green. Wings light brownish.

Vestiture. Face laterally covered by short, appressed, silvery setae; frons, vertex,

mesosoma and metasoma dorsally covered by short (1.0 MOD), erect, whitish setae. Body ventrally with longer setae.

Male. Unknown.

DISTRIBUTION. Iran, Turkmenistan.

ETYMOLOGY. The species is named after the late Gerti (Gertrude) Heim

(Luzern, Switzerland), who friendly supported my studies on Chrysididae for several years, while studying the Linsenmaier collection.
