Figs 51–53 Diagnosis. A robust, medium-sized, brown Winnertzia with broad wings. Male genitalic structures characteristic of this species are as follows ( Fig. 51 ). The gonocoxal synsclerite has a sharply contoured, V-shaped emargination framed by a broad, darkly pigmented margin (↓ 4 ); the gonocoxal apodemes are short-subtriangular (↓ 5 ); the elongate, apically rounded gonostylus has a fairly long and narrow pectinate claw, whose position is slightly subapical (↓ 6 ); and the aedeagal apodeme is uniformly broad. Females and preimaginal stages of W. normalis are unknown. Other male characters. Body size 2.1–2.5 mm . Head. Eye bridge 5–6 ommatidia long dorsally. Antenna longer than half body. Scape slightly larger than pedicel, both concolorous with flagellum. 12 flagellomeres, translucent sensilla present on flagellomeres 1–11. Fourth flagellomere: neck 0.5 times as long as node; node 1.6 times as long as broad; sensory hairs numerous; both lateral and medial translucent sensilla obliquely aligned, elongate leaf-shaped, for the most part closely adpressed to flagellomeral body ( Figs 52–53 ). Palpus as long as head height, 4 setae-bearing segments; apical segment longest of all. Labella normal size. Thorax. Pronotal setae 20–22. Anepimeral setae absent. Lateral mediotergal microtrichia large. Parascutellar area bright, vaguely contoured. Wing shorter than body, 2.2 times as long as broad. Costal cell reinforced. M 4 long, gently bent, CuA strongly bent, both veins extending to edge of wing. Legs. Scales pointed. Basitarsal spines absent. Fore tibia 1.2 times length T 2 . Acropods: claws slightly bent, basal tooth large; empodia vestigial. Abdomen. Pleural membrane setose. Genitalia ( Fig. 51 ). Ninth tergite shorter than half gonopodal length; setae confined to posterior portion; posterior edge slightly concave and reinforced medially; anterior edge indistinct. Gonocoxal synsclerite slightly broader than long; setae near base of emargination conspicuously large; a small portion ventrobasally non-setose; ventrobasal edge straight; ventro- and dorsoposterior portions ending at same level. Gonostylus almost 2.5 times as long as broad, nearly parallelsided; basolateral apophysis small, angulated. Solid basal portion of aedeagal apodeme moderately long. Aedeagal bulge with closely spaced rows of tiny spikes. Tegmen largely membranous, vaguely contoured except for basal half which is more sharply outlined, slightly narrowed towards broadly rounded apex; flaps large, clearly contoured, without microtrichia; parameral apodemes of moderate size. Etymology. The Latin normalis means normal, an allusion to the fact that this species lacks any eye-catching features. Type material. Holotype .
