Gonatocerus ( Lymaenon) mediterraneus Donev & Triapitsyn , sp. n.
( Figs 8–10 View FIGURE 8 View FIGURES 9, 10 )
Type material. Holotype: female ( Fig. 8 View FIGURE 8 ) on slide [PUPB] labeled: 1. “20.07– 10.08.00, Creet [sic] Island, Iraklio, Greece, Leg. D. Petrov”; 2. “Fam. Mymaridae Gonatocerus mediterraneus sp. n.? holotype ♀ Det. At. Donev”; 3. [red] “ Gonatocerus ( Lymaenon) mediterraneus Donev & Triapitsyn HOLOTYPE ♀”. The collecting locality is Heraklion (Iraklion), Crete Island, Crete, Greece; the specimen was captured 20.vii–10.viii. 2000 in a Malaise trap. The holotype is in fair condition although insufficiently cleared, mounted laterally.
Paratype: GREECE. CRETE, Crete Island, Heraklion, 10–20.vii.2000, D. Petrov [1 ♀ on slide, PUPB]. The paratype lacks one fore wing.
Description. FEMALE ( holotype and paratype). Body length 1107–1218 µm. Head, mesosoma and apical 0.75 or so of gaster brown; remainder of gaster, antenna, and legs light brown or golden brown to brown.
Antenna ( Figs 8 View FIGURE 8 , 9 View FIGURES 9, 10 ) with radicle 0.26–0.29× total length of scape, rest of scape 3.1–3.2× as long as wide, faintly scuptured; pedicel longer than F1and F2 together; F1 and F2 shorter than following funicle segments, F3 a little longer than F2, F4 longer than F3 and shorter than F8 when lacking mps but as long as F8 when bearing a mps, F5 as long as F6 and a little longer than F7, and notably longer than F8, F5, F6, and F7 about 2× as long as wide; mps on F4 (usually 0 but 1 on one antenna in the holotype), F5 (2), F6 (2), F7 (2), F8 (2); clava with 9 mps, 3.5–3.6× as long as wide, a little shorter than combined length of F6–F8.
Mesosoma ( Fig. 8 View FIGURE 8 ). Propodeum laterally slightly convex. Fore wing ( Fig. 8 View FIGURE 8 ) 2.6–2.9× as long as wide; longest marginal seta 0.16–0.2× maximum wing width; disc completely bare behind submarginal vein, with just a few setae behind the middle and apex of marginal vein (cubital row of setae composed of just a few setae, not extending to base of marginal vein, thus leaving a bare area behind base of marginal vein, Fig. 10 View FIGURES 9, 10 ), and densely setose elsewhere except for a very small, narrow bare area just beyond stigmal vein. Hind wing ( Fig. 8 View FIGURE 8 ) 18–19× as long as wide; disc with a few scattered setae; longest marginal seta about 2.0–2.3× maximum wing width.
Metasoma. Gaster ( Fig. 8 View FIGURE 8 ) longer than mesosoma. Ovipositor occupying about 0.9× length of gaster, not or just barely exserted beyond its apex; ovipositor 2.2× length of mesotibia.
Measurements (µm) of the holotype. Body 1107; head 191; mesosoma 412; gaster 554; ovipositor 541. Antenna: radicle 51; rest of scape 124; pedicel 58; F1 25; F2 24; F3 28; F4 30 (42); F5 57; F6 57; F7 52; F8 42; clava 145 (148). Fore wing 935:320; longest marginal seta 67. Hind wing 680:36; longest marginal seta 83.
MALE. Unknown.
Hosts. Unknown.
Diagnosis. In Triapitsyn (2013), G. mediterraneus keys to the same couplet as G. ( Lymaenon) karakum Triapitsyn (known from Italy and Turkmenistan), the only other described Palaearctic species of G. ( Lymaenon Walker ) that has the fore wing with the cubital row of setae not extending to the base of the marginal vein ( Fig. 10 View FIGURES 9, 10 ). Females of G. mediterraneus differ from those of G. karakum by having 2 mps on F5 and F6 (without mps on F5 and F 6 in G. karakum ), and also by a notably longer ovipositor, which is 2.2× as long as mesotibia (1.3–1.4× as long as mesotibia in G. karakum ) (Triapitsyn 2013). The following couplet is thus modified accordingly in Triapitsyn’s (2013: 39–40) key to females of G. ( Lymaenon ) to accommodate G. mediterraneus :
6(3) Fore wing with cubital row of setae not extending to base of marginal vein ( Fig. 10 View FIGURES 9, 10 ) [and Fig. 101 in Triapitsyn (2013)]... 6’ - Fore wing with cubital row of setae extending to base of marginal vein........................................... 7 6’(6) F5 and F6 without mps...................................................... G. ( Lymaenon) karakum Triapitsyn - F5 and F6 each with 2 mps................................. G. ( Lymaenon) mediterraneus Donev & Triapitsyn sp. n.
