Polana (Varpulana) intricata   sp. nov.

( Figs 32–43 View FIGURES 32 – 43 , 99 View FIGURES 97 – 102 )

Diagnosis. Pronotum with two small black spots behind eyes, near anterior margin. Subgenital plate ( Fig. 39 View FIGURES 32 – 43 ) elongated, 4.2 times longer than wide. Style ( Fig. 41 View FIGURES 32 – 43 ) with ventral protrusion of blade elongated. Aedeagus ( Figs 42, 43 View FIGURES 32 – 43 ) with atrial processes elaborated and shaft strongly curved anterad.

Description (male). Length (holotype) 6.7mm, Head ( Fig. 32 View FIGURES 32 – 43 ) in dorsal view with median length approximately three-tenths of interocular width. Other characteristics as in the generic description.

Coloration. Head and thorax ( Fig. 32 View FIGURES 32 – 43 ) brownish. Face ( Fig. 33 View FIGURES 32 – 43 ) without maculae. Crown ( Fig. 32 View FIGURES 32 – 43 ) with two small rounded black spots behind ocelli on posterior margin. Pronotum with two small black spots behind eyes, near anterior margin; in lateral view ( Fig. 34 View FIGURES 32 – 43 ) proepimeron with a black elongate macula below pronotal carina. Forewing ( Fig. 35 View FIGURES 32 – 43 ) pale brown with black maculae on crossed veins of discal and apical cells and apex of anal veins. Legs brownish.

Male terminalia. Sternite VIII ( Fig. 36 View FIGURES 32 – 43 ) 1.1 times wider than long; posterior margin with middle portion slightly produced and rounded. Pygofer ( Fig. 37 View FIGURES 32 – 43 ) 1.6 times longer than maximum height; dorsal margin with short process at base; apex rounded; posterior margin ( Fig. 38 View FIGURES 32 – 43 ) in ventral view, with small rounded protrusion near apex. Subgenital plate ( Fig. 39 View FIGURES 32 – 43 ) elongated, 4.2 times longer than wide; apex rounded. Connective ( Fig. 40 View FIGURES 32 – 43 ) T-shaped, with rami shorter than stalk; stalk very elongate. Style ( Fig. 40 View FIGURES 32 – 43 ), in dorsal view, with outer lobe small and rounded; in lateral view ( Fig. 41 View FIGURES 32 – 43 ), ventral protrusion elongated, approximately three times longer than its maximum width, apex curved ventrally and serrated; blade elongated, same height along its entire length, apical third slightly curved dorsally, apex acute. Aedeagus ( Figs 42, 43 View FIGURES 32 – 43 ) with atrial processes elaborated, narrow basally and acute apically, anterior margin with small tooth at basal third, posterior margin with conspicuous process at mid-length, partially involving the aedeagal shaft and with two cute tips: one small directed anterad and one larger directed posterad; shaft elongated and strongly curved anterad with two flattened processes arising on dorsal margin at basal twothirds, apex acute and curved laterally; aedeagal apex membranous without processes.

Female unknown.

Etymology. The specific epithet, intricata   comes from the Latin “intricatus” and means complicated. It refers to the aedeagus with a complex shape.

Material examined. Holotype male: " Brasil, Bahia,\ Encruzilhada \ XI.1975 \ M. Alvarenga leg." ( DZUP).  

Remarks. Polana (V.) intricata   sp. nov. is similar to P. (V.) sapitanduva   sp. nov. and P. (V.) naja   sp. nov. in having the style with a more elongated ventral protrusion than the other Varpulana species. However, the new species is most similar to P. (V.) sapitanduva   sp. nov. in having the style with blade slightly curved. Polana (V.) intricata   sp. nov. differs from the other species in the more elongated subgenital plate and the atrial processes with a conspicuous middle process, partially involving the aedeagal shaft.
