Gonatocerus janzeni Huber , sp. n.

( Fig. 108 View FIGURE 108 )

Type material. Holotype ♀ ( AMNH), box with Baltic amber inclusion labelled: “ Holotype ♀ Gonatocerus janzeni Huber ”. The type locality is somewhere in the present day Baltic region.

Diagnosis. Among fossils species of Gonatocerini (two species of Archigonatocerus and three of Cosmocomoidea ), G. janzeni differs by the combination of relatively slender funicle segments, narrow fore wing, and long gaster and ovipositor sheaths ( Fig. 108 View FIGURE 108 a).

Description. FEMALE. Body length 780 (holotype). Colour. Body dark brown; scape, radicle and legs brown ( Fig. 108 View FIGURE 108 a). Head. Eye large, ventrally separated moderately from back of head. Gena width in lateral view at level of lower margin of eye less than eye length. Occiput without transverse sutures. Antenna. Funicle segments fl5–fl8 with 2 mps; clava undoubtedly with mps but these not visible. Antennal measurements (length/ width): scape ~95/34, pedicel 49/36, fl 1 38/18, fl 2 39/20, fl 3 42/20, fl 4 47/22, fl 5 60/24, fl 6 59/24, fl 7 64/24, fl 8 62/31, clava 144/40. Scape with ventral margin moderately convex and with radicle ~40, about 0.33× scape length. Mesosoma. As in generic description. Wings. Fore wing length 475, width 122, length/width 3.89, longest marginal setae 58. Venation length 200, about 0.42× wing length. Parastigma + stigmal vein length 150, hypochaeta not visible (broken off?) ( Fig. 108 View FIGURE 108 b) but presumably present. Hind wing length ~340, width 12, longest marginal setae 55. Metasoma. Petiole short (not visible). Gaster about 1.3× as long as mesosoma. Ovipositor sheath length 580, 2.1× metatibia length (276) and slightly exserted (40) beyond gaster apex.

MALE. Unknown.

Etymology. The species is named after Jens-Wilhelm Janzen, Seevetal, Germany, a dedicated collector and identifier of amber fossils, whose collection is now in AMNH.
