Gonatocerus (Lymaenon) karakum Triapitsyn View in CoL , sp. n.

( Figs 99–102 View FIGURES 99 – 102 )

Type material. Holotype female [ UCRC] on slide: ITALY. LAZIO , Roma Prov., Castelporziano Presidential Estate , Fosso di Trafusina , 41°46.670’N 12°24.751’E, 30 m, 11–12.vi.2003, M. Bologna, J. Munro, A. Owen, J.D. Pinto, YPT (marsh, riparian habitat) [ UCRC ENT 294202 ]. GoogleMaps Paratype: TURKMENISTAN. AHAL, Central Kopet Dag Mts., Chuli Canyon , 11.vi.1992, S.V. Triapitsyn [1 Ƥ on slide, UCRC].

Description. FEMALE. Body length (paratype) 910 µm. Head and appendages mostly brown except lateral and posterior edges of midlobe of mesoscutum and four basal segments of all tarsi light brown.

Antenna ( Fig. 99 View FIGURES 99 – 102 ) with radicle 0.27–0.32× total length of scape, rest of scape 2.8–3.1× as long as wide, faintly sculptured; pedicel longer than F1; F1 and F2 shorter than following funicle segments, F7 and F8 subequal and longer and broader than preceding funicle segments; F1–F6 without mps, mps on F7 (1 or 2) and F8 (2); clava with 8 mps (but with 9 mps on one antenna in the holotype), 2.8–3.6× as long as wide, about as long as combined length of F6–F8.

Mesosoma ( Fig. 100 View FIGURES 99 – 102 ). Propodeum with submedian lines moderately close to each other. Fore wing ( Fig. 101 View FIGURES 99 – 102 ) 2.8–2.9× as long as wide; longest marginal seta 0.29–0.32× maximum wing width; disc with a slight brownish tinge, completely bare behind submarginal vein, with just a few setae behind the middle and apex of marginal vein (cubital row of setae not evident, not extending to base of marginal vein, thus leaving a bare area behind base of marginal vein), and densely setose elsewhere except for a very small, narrow bare area just beyond stigmal vein. Hind wing ( Fig. 102 View FIGURES 99 – 102 ) 13–14× as long as wide; disc densely setose and with a slight brownish tinge; longest marginal seta about 1.9× maximum wing width.

Metasoma ( Fig. 100 View FIGURES 99 – 102 ). Gaster longer than mesosoma. Petiole about 2.7× as wide as long. Ovipositor occupying 0.7–0.8× length of gaster, barely exserted beyond its apex; ovipositor length: mesotibia length ratio 1.3– 1.4:1.

Measurements (µm) of the holotype. Mesosoma 375; petiole 25; gaster 467; ovipositor 357. Antenna: radicle 45; rest of scape 121; pedicel 58; F1 27; F2 27; F3 35; F4 33; F5 42; F6 39; F7 52; F8 51; clava 142. Fore wing 867:314; longest marginal seta 90. Hind wing 707:52; longest marginal seta 100.

MALE. Unknown.

Diagnosis. Gonatocerus karakum is the only known Palaearctic species of the subgenus that has the fore wing with the cubital row of setae not extending to the base of the marginal vein ( Fig. 101 View FIGURES 99 – 102 ).

Etymology. The species name (a noun in apposition) is that of Karakum Desert which occupies much of the area of Turkmenistan.

Hosts. Unknown.
