Papaverodinia willkeniae gen. et sp. nov. urn:lsid:zoobank.org:act: D1B5CFAB-3CFA-454B-9CB5-E6EB120A744B Figs 48–72, 77–78, 81 Diagnosis The 3 rd pair of fronto-orbital setae originated at the level or above of the anterior ocellus. Fronto-orbital plate entirely yellow. Cercus with opening in inverted V-shape. Inner and outer surstyli weakly fused at proximal end. Inner surstylus, slightly backward curved following curvature of the anterior margin of the outer surstylus, in lateral view. Outer surstylus enlarged distally, ‘ice cream ladle-shaped’ in lateral view.

Description Measurements (Figs 48–55). Body length 4.6 mm; wing: length 0.4 mm, width 0.5 mm. Male HEAD (Figs 48–51). Height 1.6 × length and 1.2 × as wide as high. Frons 1.4 × as wide as long, with lateral margins yellow from 3 rd pair fronto-orbital seta and encompassing bases of 1 st and 2 nd pair fronto-orbital setae, 3 rd pair of fronto-orbital setae originated at level or above of anterior ocellus; fronto-orbital plate either entirely yellow (Fig. 50). Lunule 0.2 mm high; 0.4 × height or length of frons. Antenna entirely brown except for yellow-orange proximal region (Figs 50–51). THORAX (Figs 48–49, 52). Mesonotum and scutellum brown, with dark brown pruinosity (Figs 49, 52). Pleuron light brown (Fig. 49). LEGS (Fig. 49). Tibia predominantly dark, except yellow at distal and proximal tips. WING (Fig. 53). Length 3.3 mm and width 1.2 mm (= 2.7 × as long as wide); veins brown. ABDOMEN (Fig. 48). Tergites brown. MALE TERMINALIA (Figs 54 –64, 77–78, 81). Epandrium brown, length and height subequal; surstylus dark yellow to light brown (Fig. 61). Cercus with opening in inverted V-shape, medial membrane slightly infuscated yellow, extended up to ½ its length, or to proximal end of cercal opening (Figs 54 –61, 77). Inner and outer surstyli weakly fused at proximal end. Inner surstylus, slightly backward curved following curvature of anterior margin of outer surstylus, in lateral view (Figs 55, 61). Outer surstylus with basal part narrow, less than ¼ of distal lobe height, enlarged distally, ‘ice cream ladle-shaped’ in lateral view (Figs 55, 61). Subepandrial sclerite with anteromedial margin in open U-shape, and posterior margin in inverted V-shape, with an angle of approximately 94° (Fig. 78). Angle of pregonite 120° (Fig. 81). Female Similar to male (in external morphology of head, thorax, wings, legs and abdomen), except as noted below: TERMINALIA (Figs 65–72). Tergite 6 entirely brown, proximal ⅔ glabrous, distal ⅓ with long and strong setae, spiracle slightly away from anteroventral margin with area of membranous insertion. Sternite 6 membranous, with anteromedial sclerotization ‘top hat-shaped’, lateromedian area subquadrangular, posterior margin with row of 9 setae (3 median, 1 pair submedian, 2 lateral pairs), subequal in length and diameter, except very short and weak submedian setae. Tergite 7 strongly fused to sternite 7; tergite 7 almost entirely membranous, except for strongly sclerotized subproximal band extending ventrally forming ring, straight on posterodorsal margin; sternite 7 concave on posteroventral margin, with short, sparse setae. Variation Male (n = 4): body length 4.0− 5.3 mm, mean 4.6 mm; wing length 3.3−4.5 mm, mean 3.9 mm; wing width 1.2−1.6 mm, mean 1.4 mm.
