C. longicaudata Japoshvili & Guerrieri sp. nov

( Figs. 1–6 )

Description. Holotype Ƥ (length including ovipositor 5.8 mm, without ovipositor 2.9 mm). Head mesoscutum, pronotum and gaster with golden-green reflections; scutellum, axilla and mesopleuron with purple and golden reflections; tegula pale yellow; antenna dark brown, scape with faint green and golden reflections; legs yellow, with mid- and hind coxae brown, fore tibia dark yellow, mid- and hind tibiae brown, last 2 segments of mid and hind tarsi brown. Head 2.2× as wide as frontovertex; mouth opening 0.5× as wide as head width and 1.1× as wide as frontovertex; FV 1.3× as long as wide in frontal view, ocelli forming an angle of about 60º; antenna ( Fig. 2 ) with scape 8× as long as broad, F1 4× as long as broad, pedicel as long as F1 and 3× as long as broad; all funicular segments longer than broad, F6 the shortest; clava elongate with sutures transverse. Relative measurements: HW 39, FV18, OOL 2 OCL 4, POL 10, OD 2.

Forewing about 3× as long as broad. Ovipositor ( Fig. 4 ) exserted, the exserted part 2.5× as long as midtibia.

Paratype Ƥ (length including ovipositor 4.4 mm, without ovipositor 2.4 mm). Fore wing venation as in Fig. 3 ; hypopygium very similar to that of C. boucheanum ( Fig. 21 ), distinctly elongate, about 2.4× as long as broad; ovipositor 3.7× as long as midtibia; gonostyli 0.67× as long as ovipositor and 2.4× as long as midtibia. Paratype 3 (length 1.9 mm). Very similar to female except for antenna ( Fig. 5 ) and genitalia ( Fig. 6 ).

Holotype and paratypes deposited at the Natural History Museum, Oslo University, Oslo, Norway.

Biology. Unknown.

Distribution. Norway.

Comments. Females of C. longicaudata are very similar to those of C. terebrator Mayr, 1876 , both having very long, exserted ovipositors, but the former can be separated by sutures on clava transverse (parallel in C. terebrator , compare Figs 2 and 7 ), and ovipositor at least 3.7× as long as midtibia (3.1× in C. terebrator ). Males of the two species can be separated by the relative length of the parameres of the genitalia (compare Figs 6 and 8 )
