( Figs 23–44 , 69, 70 ) Diagnosis. Forewing ( Fig. 26 ) translucent light brown with darker veins. Aedeagus ( Figs 34, 35 ) with apodemal processes with rounded subapical lobe at dorsal margin; shaft without processes at mid-length, with pair of acute subapical processes. Measurements (mm). Holotype male: total length 6.8. Paratype (male), 6.2−6.8; (female), 7.2−7.4. Description. A s in description of the subgenus. Coloration. Head and thorax ( Figs 23 , 69, 70 ) light brown. Crown ( Fig. 1 ) with two small rounded black spots behind ocelli, near posterior margin. Pronotum ( Fig. 23 ) with six black maculae near anterior margin; posterior margin dark brown. Mesonotum ( Fig. 23 ) with lateral angles yellow. Face ( Fig. 2 ) yellow, without maculae. Proepimeron ( Fig. 3 ), with small black macula below pronotal carina. Forewing ( Fig. 26 ) translucent light brown, with brown to dark brown veins; apex smoky. Legs yellow. Male terminalia. Sternite VIII ( Fig. 27 ) 1.4 times wider than long; posterior margin with median third produced and rounded. Valve ( Fig. 28 ) with posterior margin broadly rounded. Pygofer ( Fig. 29 ) short, 1.5 times longer times longer than maximum height; dorsal margin with short process at base; ventral margin broadly rounded; apex broad; posterior margin ( Fig. 30 ), in ventral view, with small and rounded protrusion near apex. Subgenital plate ( Fig. 31 ) 3.8 times longer than wide; lateral margins approximately parallel; apex rounded. Connective ( Fig. 32 ) linear, with stalk very long and wide, two times longer than arms width. Style ( Fig. 32 ), in dorsal view, with outer lobe small and subacute; in lateral view ( Fig. 33 ), ventral protrusion long, approximately two times longer than wide, apex serrated; blade slightly curved dorsally, not tapered toward apex; apex rounded with small dentiform process. Aedeagus ( Figs 34, 35 ) with apodemal processes slender and directed dorsally, almost as long as shaft length, dorsal margin with rounded subapical lobe, apex very narrow and acute; shaft slightly curved dorsally, without processes at mid-length, with pair of short acute subapical processes; shaft apex membranous and rounded. Female terminalia. Sternite VII ( Fig. 36 ) 1.8 times wider than long; posterolateral corners rounded; posterior margin excavated laterad of rounded median lobe. First valvifer ( Fig. 38 ) 1.7 times higher than long. First valvula ( Fig. 40 ) gradually tapered toward apex. Second valvula ( Fig. 42 ) apex with approximately six small teeth. Other characteristics as in the description of the subgenus. FIGURES 23–35. P.

Scale bars in mm. Remarks. Polana (V.) feitosai sp. nov. is most similar to P. (V.) grossii in having the forewing with darker veins ( Fig. 26 ) and the style with the apex rounded and a small dentiform process ( Fig. 33 ). However, the new species can be easily separated by the aedeagus with apodemal processes narrow with a rounded subapical dorsal lobe ( Fig. 34 ) (apodemal processes very wide in P. (V.) grossii ) and the shaft without processes at mid-length (with two pairs of processes at mid-length of shaft in P. (V.) grossii ).
