ETYMOLOGY. Named in honor of Gordon Ramel in recognition of his collecting effort in the Kerkini Lake National Park and his contribution to the knowledge of the biodiversity of Greece.

DESCRIPTION. FEMALE. Holotype Ƥ: length 1.65 mm. Head ( Fig. 3 View FIGURES 1 – 6 ) green, with golden, coppery, and magenta reflections on vertex and a wide, transverse, bright magenta stripe between anterior ocellus and upper limit of scrobal depression, and rest with golden and coppery reflections under some angles, especially on scrobal depression; maxillary and labial palpi white. Antenna with scape pale-brown with magenta and green lustres under some angles of light and darker dorsal and ventral margins and extreme base; pedicel and F1 concolorous with scape, F2–F6 white, F7, F8 and clava dark brown ( Fig. 52 View FIGURES 45 – 54 ). Mesosoma ( Figs 13 View FIGURES 7 – 16 , 23 View FIGURES 23 – 30 ) with pronotum yellowishbrown dorsally and yellow laterally, with faint metallic lustre under some angles of light and a small, almost black spot on lateral corner anterior to each spiracle; mesoscutum brown with strong golden-green reflections, with a blue hue on convex anterior part and intense copper reflections on median depressed area; scutellum and axillae contrasting in color, the axillae yellow and scutellum green with golden and coppery reflections; prepectus, tegula, dorsellum and propodeum brown, the latter with some metallic lustre; acropleuron brownish-yellow, mesepisternum with some brown tinges. Fore wing with pale brownish venation except median part of submarginal vein lighter; disc not conspicuously infuscate, with a brownish tint at base of basal cell, pale brownish beyond parastigma and with a darker, fuzzy spot behind it ( Figs 23 View FIGURES 23 – 30 , 49 View FIGURES 45 – 54 ). Legs with contrasting light and dark regions, fore leg yellowish except brownish claws, posterior surfaces of apical half of femur and tibia, and dirty-white knee; mid leg with yellowish-brown coxa, trochanter and tarsus, and whitish-yellow femur and tibia except femur with a brown spot on apical half of posterior surface extending slightly on the dorsal surface and tibia with a brown subbasal ring; hind leg with brownish coxa and femur except ventral side paler, tibia with dirty-white basal half, whitish-yellow apex, and a large brown subapical ring interrupted ventrally, tarsus whitish-yellow, with brownish last tarsomere. Metasoma with Mt1 brownish, Mt2 and Mt3 translucent, whitish, with a broad brownish band across Mt2, Mt4–Mt8 brown, with faint multicolored metallic lustres. Ovipositor sheath with a broad, dirty-white ring, and brown basal 2/5 and apical 1/5.

Head shiny, with alutaceous sculpture on lower face, occipital area, gena and temples, but area near malar sulcus more polished, frontovertex shining with sparse setiferous pinprick-like punctures; scrobal depression shallow and wide, slightly Ω-shaped, imperceptibly merging into frons, in lateral view with undifferentiated lower parascrobal region, uniformly coriaceous-granular with granules slightly smaller than an ommatidium ( Figs 3 View FIGURES 1 – 6 , 50 View FIGURES 45 – 54 ); setae on frontovertex black and recumbent, those on lower face translucent. Frontovertex 0.4× head width, with ocelli arranged in a nearly right triangle. Eye inconspicuously microsetose with setae slightly shorter than an ommatidium. Toruli with upper margin in line with lower orbit. Scape in dorsal view strongly curved, in outer view about 3× as long as wide, wider medially with ventral and dorsal margins symmetrically evenly curved and with an inconspicuous ventral lamina; in outer view pedicel 1.8× as long as wide, F1 clearly transverse, F2 only slightly longer than wide, and following segments all longer than wide, of similar length but gradually broadened toward clava; clava 2.75× as long as wide, only slightly shorter than two and a half apical funiculars; pedicel plus flagellum 1.5× HW. Relative measurements: HW 29, FV 12, HL 15, HH 22, EL 15.5, EW 11.5, MS 9.5, LOL 3, OOL 2, POL 4, MPOD 3, SL 14.5, SW 5.

Mesosoma with pronotum medially divided, with inconspicuous alutaceous sculpture and sparse semierect setae, 10 of which are longer and arranged in a line along posterior margin; mesoscutum smooth and shiny except for a few longitudinal rugae in front of anterior angle of scutellum, with 4 setae on this sculptured area and with one longer seta on each side of it, with median depressed area bare in rest, convex median lobe inconspicuously coriaceous and with sparse translucent short setae, lateral lobes carinate at extreme posterior end, inconspicuously coriaceous dorsally and on sides, and with sparse translucent short setae. Axillae obliquely alutaceous with narrow cells, appearing striate, with anterior edge in same plane as scutellum base, and convexly sloping posteriorly; scutellum convex, dorsally circularly reticulate (mesh size much smaller than an ommatidium), but becoming semicircularly imbricate-coriaceous posterodorsally and posterior surface with gradually effaced sculpture; setation of axillae and scutellum inconspicuous, with 4 setae on scutellum (2 on each side) and 5 setae on posteriorly sloping surface of axilla. Dorsellum with a large rounded median lobe covering apex of scutellum. Propodeum with narrow and abruptly sloping plical depression, plical region narrow, anteriorly with broadly Ushaped and posteriorly with Λ-shaped carinae nearly touching medially and with a very short median carina, posterior carina raised into low triangular translucent flange; callar region slightly convex with sparse, long white setae in outer half, and moderately large spiracle much smaller than a posterior ocellus and separated from anterior margin by distance equal to its own smallest diameter. Acropleuron with sparse translucent setae only below prepectus, imperceptibly alutaceous in extreme anterior end and rest polished; cuticle very thin so that attachment site of mesotergal-mesopleural muscle clearly visible; mesepisternum alutaceous, with sparse white setae except for extreme anterior region, the setae longer in front of mid coxa and along acropleural sulcus. Hind coxa smooth, with sparse, long, translucent setae along ventral margin of outer surface and with a few setae along dorsal edge. Mesotibia with 4 apical pegs. Fore wing 2.7× as long as wide; basal cell entirely microsetose, the setae dark at base and translucent elsewhere; costal cell with a few setae at base on ventral side and with a single median line of small, inconspicuous setae; distal end of costal cell, parastigma and area behind it with longer, darker setae than rest of disc which is evenly setose with short, brownish setae; venation with long uncus and stigma not enlarged ( Figs 36 View FIGURES 31 – 40 , 51 View FIGURES 45 – 54 ), cc: mv: stv: pmv: uncus: u-pmv = 3.6: 4.9: 1: 1.8: 0.55: 0.7.

Metasoma with terga finely reticulate, sparsely setose on sides; Mt7 reticulate-polished basally and polished in apical half; Mt8 (syntergum) polished, with sparse, long, erect black setae on ventrolateral side; Mt2–Mt4 emarginate medially, Mt5 only slightly emarginate; Mt8 (syntergum) with a distinct dorsal surface anterior to emargination surrounding posteriorly facing anal sclerite. Ovipositor sheath 0.8× hind tibia length. Relative measurements: MTL 48, MTW 26, OL 23.
