frontal prominence than in prolongata, A

14 is slightly less transverse than in prolongata, (length : width ratio about 8 : 9), and relativa has gaster behind petiole fully 2.5 times as long as wide (Fig. 8), in prolongata it is only about twice as long as wide. Antenna of relativa uniformly dark brown. Marginális 0.6 times as long as its distance from basalis, radial cell 2.6 times as long as marginális. Petiole 1.5 times as long as wide (Fig. 8). Differs from A. nigriceps (Kieffer, 1907) in having preapical antennái segments transverse, in having facial furrows, and in having emargination of frontal prominence less deep. Male. Unknown. Holotype female: Norway (EIS 97), NTI, Mosvik, Kilen 14. VIII-7. IX. 1994, Malaise trap (NINA leg.). Caught at station 19 in the control area, cf. Tommerâs and Breistein (1995). Paratypes (5 females): Same data as holotype, 1 female; same data but caught at station 5 in the control area, 1 female; same locality 25. VII—

14. VIII. 1994, caught at station 5 in the control area, 1 female; same data but caught at station 36 in the area with fine grained fragmentation, 2 females. All Malaise trap and NINA leg.
