Diagnosis. A medium-sized, brown Winnertzia with short antennae. This is the first species of Winnertzia described to have a solid tooth, not a pectinate claw, at the gonostylar apex ( Fig. 43 View FIGURES 41–47 , ↓ 1). (We know of another such species in Costa Rica.) As another peculiarity, the gonostylar apex is blunt-ended, not convex as usually found in Winnertzia (↓ 2). Females and preimaginal stages of W. dentata are unknown.
Other male characters. Body size 1.9 mm. Head. Eye bridge 3–4 ommatidia long dorsally. Antenna half as long as body. Scape and pedicel same size, both concolorous with flagellum. 11 flagellomeres, apical flagellomere long, composed of two nodes, flagellomeres 1–9 with translucent sensilla. Fourth flagellomere: neck 0.7 times as long as node; node 1.5 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 41–42 View FIGURES 41–47 ). Palpus slightly shorter than head height, 4 setae-bearing segments; apical segment longest of all. Labella of normal size. Thorax. Pronotal setae about 30. Anepimeral setae absent. Lateral mediotergal microtrichia large. Parascutellar area bright, vaguely contoured. Wing shorter than body, 2.4 times as long as broad. Costal cell reinforced. M 4 long, gently bent just as CuA, both veins extending to edge of wing. Legs. Scales pointed. Basitarsal spines absent. Fore tibia 1.8 times length T 2. Acropods: claws slightly bent, basal tooth large; empodia vestigial. Abdomen. Pleural membrane setose. Genitalia ( Fig. 43 View FIGURES 41–47 ). Ninth tergite about half gonopodal length; setae largely confined to lateroposterior portions; posterior edge with deep, slightly reinforced emargination; anterior edge indistinct. Gonocoxal synsclerite slightly broader than long; a large ventrobasal portion non-setose; ventrobasal edge straight; ventral emargination U-shaped, sharply contoured and slightly convex basally; ventroposterior portions protruding beyond dorsoposterior portions which are blunt-ended; dorsal apodemes short. Gonostylus 2.5 times as long as broad, nearly parallel-sided; basolateral apophysis large, slightly angulated. Aedeagal apodeme parallel-sided with slightly constricted apex; solid basal portion long. Aedeagal bulge with rows of tiny spikes, its anterior edge well-marked as transverse line. Tegmen vaguely contoured, especially medially, slightly narrowed towards rounded, slightly reinforced and microtrichose apex; flaps inconspicuous, narrow; parameral apodemes large.
Etymology. The Latin adjective dentata means dentate, with reference to the solid gonostylar tooth characteristic of this species.
