SPECIMENS EXAMINED. Holotype – ♂, Turkmenistan: Kara-Kala [=Makh-

umkuli], 6.VII.1955, leg. A. Ponomareva [ZIN]. Paratypes: 1♂, same locality, 7.VII

1955 [ZIN]; 3♂, 9.VIII.1955 [ ZIN, PRC] ; 1♂, 10.VII 1955 [ ZIN] .

DIAGNOSIS. Chrysis vittoriorosai sp. n. belongs to the C. aestiva species group. It is separated from C. aestiva Dahlbom, 1854, C. aurelia Balthasar, 1953,

C. maderi Linsenmaier, 1959, C. rosai Arens, 2017 and C. martinella du Buysson,

1900 by elongate teeth on apical margin of T3 and shape of genital capsule; from C.

interjecta du Buysson, 1895 by wider face; longer F1; deeper and larger metasomal punctures; third metasomal segment with no aligned pits of the pit row; inner apical teeth distinctly longer than lateral ones; body colouration and shape of genital capsule.

DESCRIPTION. Body length 7.5 mm. Fore wing length 5.0 mm. M ale. OOL =

1.6 MOD; POL = 2.2 MOD; MS = 1.7 MOD; relative length of P:F1:F2:F3 = 1.0:

1.7:1.1:0.9.

Head. In full face view, length 1.7 mm, width 2.2 mm. Apex of clypeus almost straight, bordered with a broad, brown rim (0.4 MOD); TFC straight, medially raised and laterally faint; brow distinctly swollen over scapal basin; scapal basin slightly hollowed, medially with a narrow, polished stripe; elsewhere densely punctate, with minute punctures of increasing diameter towards compound eye, and covered with silvery, appressed setae. Vertex with small, reticulate punctures almost polished in front of mid-ocellus, with a deep, narrow, elongate fovea lateral to posterior ocelli.

Malar space long, 1.7 MOD, yet shorter than F1. Genal carina fully developed up to mandibular joint. Subantennal distance about 1 MOD. Mandible with subapical tooth.

Mesosoma. Length 3.0 mm; width (PPW) 2.1 mm. Pronotum anteromedially depressed, with relatively deep and narrow anteromedian groove, exceeding half pronotal length; reticulate punctation, with punctures twice as large as those on vertex,

with scattered small punctures on interstices. Mesoscutum basally with larger punctures, denser and subreticulate; on lateral lobes with double punctation and punctures smaller than those on median lobe; notauli and parapsidal lines complete; notauli as deep lines. Mesoscutellum with large, reticulate punctures (up to 0.5 MOD), with shining interstices; metascutellum with denser and larger punctures, without interstices. Mesopleuron with dense, irregular punctures; episternal sulcus well marked.

Propodeal teeth small, subparallel and pointing backwards.

habitus, lateral view; 29 – head, frontal view; 30 – metasoma, postero-lateral view. Scale bar

= 1.0 mm.

Metasoma. Length 3.4 mm. Punctation on T1 with large, scattered punctures, polished interstices with some shallow, tiny punctures. T2 with large, deep punctures,

with tiny punctures on interstices; punctures smaller and scattered on the posterior third; longitudinal median carina present. T3 with reticulate punctures; pits of the pit row large, round and deep, not aligned, because median ones are lifted up; median carina present. Black spots on S2 large, subrectangular, covering almost the whole sternum length, medially separated by a thin line.

Coloration. Body green to light blue; deep blue on the second half of T3 , including pit row and apical teeth. T2 and anterior part of T3 from golden-greenish to red in some paratypes. Body ventrally green, darker to bluish on sterna. Mandibles brown, basally green. Scape, partly green, pedicel and flagellum black. Legs green with brown tarsi. Tegulae metallic green. Wings hyaline, with light brown nervures .

Vestiture. Body covered by short (1.0 MOD), erect, whitish setae.

Female. Unknown.

DISTRIBUTION. Turkmenistan.

ETYMOLOGY. The species is named after my father, Vittorio Rosa (Bernareggio, Italy), renowned Italian entomologist, who introduced me in the study of

Entomology and Chrysididae in particular.
