Archigonatocerus longivena Huber , sp. n.

( Fig. 40 )

Type material. Holotype ♀ ( AMNH), box containing amber inclusion labelled “ Holotype ♀ Archigonatocerus longivena Huber ”. The type locality is somewhere in the present day Baltic region.

Diagnosis. Archigonatocerus longivena is a slightly larger species than A. balticus . The main differences are the longer venation and ovipositor sheaths, and presence of mps on fl3 and fl4.

Description. FEMALE. Body length 1715 (holotype). Colour. Body probably brown, but entirely covered by a thin cloudy film of air so head, mesosoma, metasoma and legs appear yellow. Head. Eye large, ventrally moderately separated from back of head. Gena width at level of lower margin of eye much narrower than eye length. Occiput apparently without transverse suture. Antenna. Funicle segments fl3–fl8 apparently with 2 mps; clava undoubtedly with mps but these not visible. Antennal measurements (length/width): scape 350/60, pedicel 80/50, fl 1 70/30, fl 2 90/30, fl3 90/40, fl4 80/40, fl5 80/40, fl6 70/40, fl7 70/50, fl8 70/60, clava 210/70. Scape with ventral margin slightly convex, and with radicle 130, about 0.37× scape length. Wings. Fore wing length 1610, width 565, length/width 2.86, longest marginal setae 150. Venation length 970, 0.60× wing length. Parastigma + stigmal vein length 540. Hind wing length 1075, width 130, longest marginal setae 110. Mesosoma. As in generic description. Metasoma. Petiole presumably short (not visible). Gaster about 2.5× as long as mesosoma. Ovipositor sheath length 1435, 2.34× metatibial length (615) and slightly exserted (300) beyond gaster apex.

MALE. Unknown.

Etymology. The species name refers to the long venation. It is treated as a noun in apposition.
