Gonatocerus (Lymaenon) ? beshbarmak Triapitsyn, 2013

( Figs 11–14 )

Gonatocerus (Lymaenon) beshbarmak Triapitsyn 2013: 58 –60. Type locality: Teke-Uyuk Ravine, 41°29’12’’N 74°35’50’’E, 1850 m, Dzhalal-Abad, Kyrgyzstan.

Material examined. GREECE. MACEDONIA, Mount Olympus, Agios Dionysios, 7.vii.1983, A. Donev [1 ♀, PUPB]. PELOPONNESE: Leonidio, 11.vii.1983, A. Donev [1 ♀, PUPB]. Mount Taygetus, 11.vii.1983, A. Donev [1 ♀, PUPB].

Redescription (based on females from Greece). FEMALE. Body length 1110–1140 µm. Head, mesosoma, legs, and most of antenna and gaster brown; radicle and base of gaster light brown.

Antenna ( Figs 11 , 12 ) with radicle 0.29–0.32× total length of scape, rest of scape about 3.5× as long as wide, faintly scuptured; pedicel longer than F1, F1 as long as F2 and a little shorter than following funicle segments, F4 longer than F3 and about as long as F8, without mps; F5 with 0 or 1 mps, F6 with 1 or 2 mps, F6 or F7 the longest of funicle segments, the latter with 2 mps, F8 usually the broadest funicle segment and with 2 mps; clava with 8 mps, 3.0–3.1× as long as wide, a little longer than combined length of F7–F8.

Mesosoma ( Fig. 11 ). Mesoscutum and scutellum apparently smooth. Fore wing ( Figs 11 , 13 ) 2.8–3.1× as long as wide; longest marginal seta 0.21–0.22× maximum wing width; disc with setae a little sparser between marginal vein and cubital row of setae then elsewhere but without any distinct bare area behind marginal vein. Hind wing ( Figs 11 , 13 ) about 23× as long as wide; disc unevenly setose (more so apically); longest marginal seta about 3.0× maximum wing width.

Metasoma. Gaster ( Figs 11 , 14 ) longer than mesosoma. Petiole about 1.6× as wide as long. Ovipositor occupying about 0.9× length of gaster, not or just barely exserted beyond gastral apex posteriorly; 1.7–1.8× length of mesotibia.

MALE. Unknown from Greece.

Diagnosis. Specimens from Greece are very similar to G. (Lymaenon) beshbarmak Triapitsyn (known from Kyrgyzstan) and key to that species in Triapitsyn (2013). The antennae of the Greek females either lack mps or have 1 mps on F5 and 1 or 2 mps on F6, whereas those from Kyrgyzstan usually have 2 (but occasionally only 1) mps on F5 and 2 mps on F6. Also, the base of gaster of the females from Crete appears to have relatively less yellow than that of those from Kyrgyzstan. We treat these differences as intraspecific variability within G. beshbarmak because presence (and number) or absence of mps, paticularly on the proximal funicle segments of the female antenna, is often prone to such variability in G. ( Lymaenon ). Therefore we tentatively assign the Greek specimens to G. beshbarmak . However, we also cannot rule out that these minor morphological differences could be indicative of two separate species, although that is less likely.

Distribution. Greece [new record (if our tentative identification is correct)], and Kyrgyzstan (Triapitsyn 2013).

Hosts. Unknown.
