Polana (Varpulana) sapitanduva  sp. nov.

( Figs 60–75View FIGURES 60 – 71View FIGURES 72 – 75, 101View FIGURES 97 – 102)

Diagnosis. Forewing ( Fig. 63View FIGURES 60 – 71) brownish with U-shaped dark brown maculae on basal half. Style ( Fig. 69View FIGURES 60 – 71) with ventral protrusion of blade elongated. Aedeagus ( Figs 70, 71View FIGURES 60 – 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. 60View FIGURES 60 – 71) in dorsal view with median length approximately half as long as interocular width. Other characteristics as in generic description.

Coloration. Head and thorax ( Fig. 60View FIGURES 60 – 71) brown without maculae. Face ( Fig. 61View FIGURES 60 – 71) without maculae. Prothorax, in lateral view ( Fig. 62View FIGURES 60 – 71), with proepimeron without maculae. Forewing ( Fig. 63View FIGURES 60 – 71) 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. 64View FIGURES 60 – 71) 1.4 times wider than long; posterolateral corners rounded; posterior margin with middle portion produced and rounded. Pygofer ( Fig. 65View FIGURES 60 – 71) 1.8 times longer than maximum height; dorsal margin with short process at base; apex blunt; posterior margin ( Fig. 66View FIGURES 60 – 71) in ventral view, with produced and rounded protrusion and rounded notch. Subgenital plate ( Fig. 67View FIGURES 60 – 71) 3.0 times longer than wide; apex tapered and rounded. Connective ( Fig. 68View FIGURES 60 – 71) T-shaped, with rami shorter than stalk; stalk wide. Style ( Fig. 68View FIGURES 60 – 71), in dorsal view, with outer lobe rounded; in lateral view ( Fig. 69View FIGURES 60 – 71), 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, 71View FIGURES 60 – 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. 72View FIGURES 72 – 75) 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. 73View FIGURES 72 – 75) 1.6 times longer than maximum height. First valvifer ( Fig. 74View FIGURES 72 – 75) 2.1 times higher than long. First and second valvulae ( Figs 74, 75View FIGURES 72 – 75) as in generic description.

Etymology. The new species name refers to the Reserva Biológica de Sapitanduva  where the holotype was collected.

Material examined. Holotype male: "Antonina—PR [Paraná]\ Reserva Sapitanduva  \ Brasil 25.V.1987 \ Lev. [Levantamento] Ent.

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.
