Tinkerbella nana Huber & Noyes

Female. Body length 225–250 μm (n=6). Colour. Very pale, the scape, pedicel, pronotum laterally, gaster laterally, and legs except apical tarsomere sometimes lighter, almost white; head, mandibles, mesoscutum, anterior scutellum and propodeum with a pale yellow or pale brown tinge, occasionally head and mesosoma, especially mesoscutum, more uniformly and extensively brown; trabeculae and a minute spot next to fore wing base dark brown; eyes and ocelli distinctly reddish (Fig. 3). Fore wing with brown tinge behind most of venation except its apex (Fig. 6). Hind wing fairly uniformly light brown from just before hamuli to slightly lighter apex. Head. 65–99 wide, with transverse reticulate sculpture on face (Fig. 9), vertex (Fig. 12), and occiput (Fig. 12). Antenna. Flagellum (Figs 5, 13) with 1 mps on fl4, 1 mps on fl5, and 4 mps on clava. Fl1–clava length/width (n=2–width or 4–length): scape, 25–30/13–14, pedicel 19–27/17–18, fl1 8–10/7–8, fl2 12–21/6–7, fl3 11–16/7–8, fl4 8–24/9, fl5 23–31/10–11, clava 59–65/15–17. Mesosoma. Mesoscutum (Figs 7, 16, 17) with slightly longitudinal, reticulate sculpture and raised meshes. Scutellum smooth anteriorly, frenum slightly wrinkled. Dorsellum smooth to slightly wrinkled. Wings. Fore wing with a few scattered microtrichae behind venation from proximal macrochaeta on, and 3 or 4 just beyond venation (Fig. 6). Fore wing length 195–240 (n=5, card mounts at 200×), width 30–50, longest marginal setae 100–155; hind wing length 145–200, width 5–10, longest marginal setae 105–130. Metasoma. Petiole 34 wide, 7 long (n=1). Gaster with segments somewhat wrinkled and sometimes transversely creased posteriorly (Figs 7, 18); gt2–gt6 each with a few fairly long, suberect setae dorsally and laterally. Male. Body length 210–230 μm (n=2). Colour light brown (Fig. 4). Fl3 and fl5 the shortest segments, less than half length of the segment following and without mps (Fig. 15).
