Type material.

Lectotype of Gasteruption minutum here designated, ♀ (MHNG) "[Switzerland], Peney, [near Genève], vii.[18]75", "Cn Tournier", “Type”, Foenus minutus Tourn., ♀", "Lectotypus, des. Madl, 1987"; Paralectotypes (4 ♀, MHNG) and all from Peney, 2 ♀ collected vii.1876, 1 ♀ vii.1875 and 1 ♀ 10.vi.1875; the paralectotypes from France and Italy were not found. Lectotype of Gasteruption longigena ♀, (ZIL) “Rõn”, [= Rönnemölla, Skane-Norrland], "Lectotypus Foenus longigena Thoms., ♀, K.-J. Hedqvist, det. 1972". Lectotype of Gasteruption boreale here designated ♂ (ZIL) from Lappland ( “Lpl.”, “borealis”); the female lectotype from Norway designated by Hedqvist (1973) is invalid because it is not from the type locality. The type series of Gasteruption abeillei from Pereneese and Landes should be in the Abeille de Perrin collection, but no specimen was found. Kieffer gives in his description as main character the short ovipositor ("Bohrer etwas kürzer als das 1. Segment"), which fits better with G. boreale/minutum than with Gasteruption assectator .

Additional material.

*Iran (Kerman, Sirac, 1640 m; Isfahan, Najafabad); *Turkey (27 km SE of Aksaray, Ihlara; Van, 30 km N of Baskale, 2700 m; Tunceli, 17 km W of Ovacik, 1250 m; Kerman, Sirac, 1640 m; Bolu, lake).

Diagnosis.

Apex of ovipositor sheath blackish or slightly brownish, if rather pale apically then pale part distinctly shorter than hind basitarsus; ovipositor sheath 0.5-0.9 times as long as hind tibia and 0.3-0.6 times as long as hind tibia and tarsus combined; occipital carina obsolescent (Figs 315, 323) and hardly protruding ventro-posteriorly; head in anterior view protruding below lower level of eyes by about basal width of mandible and mandibular condylus distinctly below lower level of eyes (Figs 320, 327), either subparallel (= typical form) or narrowed ventrally (f. boreale)); in lateral view condylar incision of malar space remains far removed from eye (Fig. 329); antesternal carina narrow; head, mesosoma laterally and scapus black; clypeus with small depression or depression obsolescent; apical antennal segment at most 1.2 times as long as third antennal segment and its colour similar to colour of medial segments; antenna of ♀ slightly shiny and blackish or dark brown; mesoscutum and head similarly coriaceous, at most mesoscutum superficially rugulose; hind coxa very densely and finely sculptured dorsally; hind tibia stout, with a distinct subbasal ivory ring and swollen, resulting in a distinctly convex ventral border (Fig. 322); hind basitarsus stout to slender (Figs 322, 325); hind tibial spurs yellowish-brown or brown; hind tarsus brown, dark brown or blackish; incision of hypopygium shallow. Males have third antennal segment usually rather long, significantly longer than second segment (Fig. 326) and fourth antennal segment shorter than second and third segments combined.

Distribution.

Europe, Iran, Turkey. New for the fauna of Iran and Turkey.

Biology.

Probably predator-inquiline of Hylaeus nests (Wall, 1994). Collected from end of May till early August.
