description: Polana (Varpulana) sapitanduva sp. nov.
(Figs 60–75, 101)
Diagnosis. Forewing (Fig. 63) brownish with U-shaped dark brown maculae on basal half. Style (Fig. 69) with ventral protrusion of blade elongated. Aedeagus (Figs 70, 71) with atrial processes elongated, approximately as long as shaft; shaft elongated and curved dorsally, with anteapical spiniform processes arising on apical fifth; apex translucent.
Description (Male). Length 7.1 mm, (n=3), female, (paratype) 8.1 mm, (n= 5). Head (Fig. 60) in dorsal view with median length approximately half as long as interocular width. Other characteristics as in generic description.
Coloration. Head and thorax (Fig. 60) brown without maculae. Face (Fig. 61) without maculae. Prothorax, in lateral view (Fig. 62), with proepimeron without maculae. Forewing (Fig. 63) brownish with U-shaped dark brown maculae on basal half of corium and darkened maculae on apex of anal veins, base of appendix and apex of fifth apical cell; transverse dark brown band on apical third. Legs brownish.
Male terminalia. Sternite VIII (Fig. 64) 1.4 times wider than long; posterolateral corners rounded; posterior margin with middle portion produced and rounded. Pygofer (Fig. 65) 1.8 times longer than maximum height; dorsal margin with short process at base; apex blunt; posterior margin (Fig. 66) in ventral view, with produced and rounded protrusion and rounded notch. Subgenital plate (Fig. 67) 3.0 times longer than wide; apex tapered and rounded. Connective (Fig. 68) T-shaped, with rami shorter than stalk; stalk wide. Style (Fig. 68), in dorsal view, with outer lobe rounded; in lateral view (Fig. 69), ventral protrusion elongated, approximately four times longer than maximum width, apex curved ventrally and serrated; blade elongated and nearly straight, same height along entire length, apex rounded. Aedeagus (Figs 70, 71) with atrial processes approximately as long as shaft, curved dorsad and then anterad, wider subapically; apex acute; shaft elongated and curved dorsally, with anteapical spiniform processes arising on apical fifth; apex membranous.
Female terminalia. Sternite VII (Fig. 72) two times wider than long; posterolateral corners rounded; posterior margin with broad median lobe, slightly more produced posteriorly than lateral angles and nearly straight. Pygofer (Fig. 73) 1.6 times longer than maximum height. First valvifer (Fig. 74) 2.1 times higher than long. First and second valvulae (Figs 74, 75) as in generic description.
Etymology. The new species name refers to the Reserva Biológica de Sapitanduva where the holotype was collected.

Remarks. Polana (V.) sapitanduva sp. nov. is most similar to P. (V.) naja sp. nov. in the style, which has the ventral protrusion of the blade elongated and arising more basally compared with the other species of Varpulana; the shape of the aedeagal shaft elongated and curved and the shape of female sternite VII. However, the new species can be easily separated from other Varpulana species by the long and curved atrial processes.
