( Fig. 8 ) Etymology. Derived from the Indonesian word “kuwat” meaning strong, with reference to the squat body of this species. Diagnosis. Females of this species are characterized by the following combination of characters: F1–F3 anelliform, F4–F5 large, with sensilla; mesosoma strongly convex; ovipositor sheaths about 1/2–1/3 length of hind tibia; pecten about half length of hind tibia. Description. Female. Body length . 0.9–1 mm . Colour . Body brownish-black, without metallic reflections; antenna with scape and pedicel yellowish, flagellum brownish; legs mostly light brown, femora and tips of tarsi darker, coxae and trochanters whitish; eyes pale reddish; mandibles yellow; wings hyaline, tegulae and venation light brown. Head . Head in frontal view 1–1.1× as wide as high. POL 1.5–2.2× OOL. Eye 1.26–1.36× as high as long, with more or less dense pilosity. Malar space about 0.3–0.4× eye height. Antenna with scape distinctly less than eye height and about equal to eye length; pedicel length about 1.7–2× width; combined length of pedicel and flagellum usually at least slightly less than head width. F1–F3 anelliform, without sensilla and progressively increasing in diameter; F4 and F5 large, with sensilla, from about quadrate to about 1.2× as broad as long; clava length about 2.3–2.9× width. Clypeal margin rounded. Mesosoma . In profile strongly arched dorsally, length about 1.2–1.3× width and about 1.3–1.4× height. Fore wing about 2.3–2.4× as long as wide; wing disc uniformly pilose, except with moderately bare areas under S and between this and apical margin; basal cell bare, basal vein with at most 4 hairs; M about 4.4–5.2× S; P from slightly shorter to slightly longer than S. Pecten about half length of hind tibia. Metasoma . Oval, moderately compressed laterally, length including ovipositor sheaths 2.3–3.2× width, from slightly shorter to slightly longer than head plus mesosoma. Hypopygium located from slightly before to slightly after middle of metasoma. Ovipositor sheaths about 1/3–1/2 length of hind tibia. FIGURE 8. Holotype of Macroglenes kuwatus sp. nov. , lateral habitus. Male. Unknown. Variation. Larger females tend to have smaller, less pilose, eyes and thus the OOL is longer compared with smaller females. Comments. Although there is a possibility that the above mentioned variability is inter-specific, other characters seem to suggest this is not the case. In my key to the Palaearctic species of Macroglenes , M. kuwatus would run to couplet 9, being closer to M. noyesi Mitroiu from Japan . It differs from this species mostly by a shorter and higher mesosoma, shorter tibial pecten, and lighter coxae. The Australian species M. ipswichi and M. congener also have two large funicular segments, but from their description they seem to be different from M. kuwatus . Both are described as blue, and with F4 (‘funicle 1’) clearly shorter than F5 (‘funicle 2’) as apparent from the description of M. congener : “As ipswichi but ring-joints larger and of equal length, funicle [1] shorter, a third of 2 instead of one-half, shorter than the ring-joints combined” (Girault 1925: 92).
