Synacra incompleta sp. n. (Figs 15-16) Female. Length: 2.6 mm. Colour black; antenna, mandibles, legs and metasoma dark brown, tibiae and tarsi lighter. Head from in front (Fig. 15) with mandibles forming a distinct beak; malar space 1.5 times the height of an eye; eyes bare. Antenna (Fig. 16) with Al as long as A2-A3 combined, Al apically with prominent angular projections; A2 2.4, A3 4.0, A4 1.8 times as long as wide, Al 1 very slightly as long as wide. Notaulices distinct but fine, missing in posterior one-fifth. Medial keel of propodeum about 1.5 times as long as that of postscutellum. Fore wing slightly reaching over apex of gaster; basalis distinct; marginális slightly as long as its distance from basalis; stigmalis and radialis very short. Petiole transverse (length : width ratio about 13 : 16), metasoma behind petiole 2.1 times as long as wide. Holotype female: Norway (EIS 97), NTI, Mosvik, Kilen 14. VIII-7. IX. 1994, Malaise trap (NINA leg.). Caught at station 17 in the area with coarse grained fragmentation, cf. Tommerâs and Breistein (1995). Synacra incompleta seems to be most similar to 5*. brachialis (Nées) sensu Hellén (1964), but this species has complete notaulices and A2 1.5, A4 2.5 times as long as wide. The name of the new species refers to the incomplete notaulices. REFERENCES Buhl. P. N. (1995): The proctotrupoid wasps of Greenland (Hymenoptera, Proctotrupoidea s. 1.). Ent. Meddr63: 7-10.
