Type material.

Holotype of Gasteruption lugubre , ♀ (ETHZ) "799", [according to original description from Switzerland, Wallis], " Gasteruption lugubre n. sp., Typ.", " Gasteruption assectator (Linnaeus), ♀, C. Saure, det. 1999". Lectotype of Gasteruption floreum here designated, ♂ (MTMA) "[Croatia], Buccari [= Bakar], 15.vi.", “Jugoslavia”, " Gasteruption floreum Szépl., det. Stohl", "Lectotypus Gasteruption floreum Szépl./ des. Madl, 1987"; 1 ♂ paralectotype (MTMA) "[Romania], Orsova, Transylvania", is much damaged and probably belongs to Gasteruption undulatum (Abeille de Perrin).

Additional material.

*Turkey (Pasli, 50 km S of Kars; Nevşeher, 10 km E of Ürgüp, W of Aksalur, 1350 m).

Diagnosis.

Apex of ovipositor sheath with a distinct white or ivory band, 1.5-1.9 times as long as hind basitarsus; dorsally head in front of occipital carina with minute medial depression (Fig. 290), in lateral view flat and occipital carina very narrow medio-dorsally and non-lamelliform (Fig. 284) or narrowly lamelliform; antesternal carina with narrow lamelliform rim, antesternal carina and prepectal carina medio-ventrally similarly developed (Fig. 295); head ventrally elongate below eyes (Figs 289, 298), gradually narrowed behind eyes in dorsal view and temples slightly convex (Fig. 290); temple about half as long as eye in dorsal view; fourth and fifth antennal segments of ♀ 1.6-1.7 and 1.4-1.6 times as long as third segment, respectively; fourth segment of ♀ 1.0-1.1 times as long as second and third segments combined; head parallel-sided below eyes and malar space about 0.9 times as long as second antennal segment (= pedicellus); vertex and frons rather matt, finely and densely aciculate-rugulose; propleuron with satin sheen, 0.8 times as long as mesoscutum in front of tegulae, densely rugose or rugulose and stout (Fig. 286); pronotal side largely rugulose; antero-lateral teeth of pronotum small and rather acutely angled; mesoscutum slender and sparsely setose (Fig. 286), with satin sheen and largely finely and densely transversely rugulose, without separate punctures and medio-posteriorly rugose; hind femur narrow and nearly parallel-sided (Fig. 291); hind coxa mainly granulate, but rugulose dorsally (Fig. 297); ovipositor sheath 0.8-1.0 times as long as body, 1.2-1.3 times as long as metasoma and 3.7-3.9 times as long as hind tibia; hind coxa and pronotal side dark brown or blackish; hind basitarsus dark brown or black (dark form) or partly ivory (pale form); length of body 8-11 mm. Male has third antennal segment twice as long as second segment, fourth segment 1.6 times as long as third segment and as long as second and third segments combined (Fig. 302); malar space slightly longer than basal width of third antennal segment.

Distribution.

Mountainous parts of C. Europe and Turkey. New for the fauna of Turkey.

Biology.

Unknown. Collected in June-July and rarely encountered.

Notes.

The holotype of Gasteruption lugubre is mutilated and the metasoma is missing. According to the original description the ovipositor sheath is longer than the metasoma, shorter than the body and black with white apex. And the fourth antennal segment ("drittes Geisselglied") of the female holotype as long as second and third segments combined. The surviving part shows an elongate head and in combination with the characters mentioned above it is obvious that it concerns most likely the dark form of Gasteruption floreum Szépligeti.
