Polana (Varpulana) feitosai

sp. nov.

Polana (Varpulana) feitosai   sp. nov.

( Figs 23–44 View FIGURES 23–35 View FIGURES 36–44 , 69, 70 View FIGURES 67–72 )

Diagnosis. Forewing ( Fig. 26 View FIGURES 23–35 ) translucent light brown with darker veins. Aedeagus ( Figs 34, 35 View FIGURES 23–35 ) 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 View FIGURES 23–35 , 69, 70 View FIGURES 67–72 ) light brown. Crown ( Fig. 1 View FIGURES 1–13 ) with two small rounded black spots behind ocelli, near posterior margin. Pronotum ( Fig. 23 View FIGURES 23–35 ) with six black maculae near anterior margin; posterior margin dark brown. Mesonotum ( Fig. 23 View FIGURES 23–35 ) with lateral angles yellow. Face ( Fig. 2 View FIGURES 1–13 ) yellow, without maculae. Proepimeron ( Fig. 3 View FIGURES 1–13 ), with small black macula below pronotal carina. Forewing ( Fig. 26 View FIGURES 23–35 ) translucent light brown, with brown to dark brown veins; apex smoky. Legs yellow.

Male terminalia. Sternite VIII ( Fig. 27 View FIGURES 23–35 ) 1.4 times wider than long; posterior margin with median third produced and rounded. Valve ( Fig. 28 View FIGURES 23–35 ) with posterior margin broadly rounded. Pygofer ( Fig. 29 View FIGURES 23–35 ) 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 View FIGURES 23–35 ), in ventral view, with small and rounded protrusion near apex. Subgenital plate ( Fig. 31 View FIGURES 23–35 ) 3.8 times longer than wide; lateral margins approximately parallel; apex rounded. Connective ( Fig. 32 View FIGURES 23–35 ) linear, with stalk very long and wide, two times longer than arms width. Style ( Fig. 32 View FIGURES 23–35 ), in dorsal view, with outer lobe small and subacute; in lateral view ( Fig. 33 View FIGURES 23–35 ), 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 View FIGURES 23–35 ) 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 View FIGURES 36–44 ) 1.8 times wider than long; posterolateral corners rounded; posterior margin excavated laterad of rounded median lobe. First valvifer ( Fig. 38 View FIGURES 36–44 ) 1.7 times higher than long. First valvula ( Fig. 40 View FIGURES 36–44 ) gradually tapered toward apex. Second valvula ( Fig. 42 View FIGURES 36–44 ) apex with approximately six small teeth. Other characteristics as in the description of the subgenus.

Etymology. The new species name is in honor of Prof. Dr. Rodrigo M. Feitosa who collected the type-series.

Material examined. Holotype male: “ Brasil, PI, Cel. José Dias\ P.N. Serra da Capivara \ 590m 08º44’3.89”S \ 42º30’10.56”W 08-12.III.\ 2016 RM Feitosa, GP Camacho & FO Martins”, ( DZUP) GoogleMaps   . Paratypes: 18♂, 2♀, same data as holotype, (3♂ DZRJ, 3♂ MZSP, 12♂, 2♀ DZUP); 2♂, “ Brasil, PI, São Raimundo Nonato\ P.N. Serra da Capivara \ 08º30’45.29”S 42º35’43.97”W \ 03-08.III.2016 Coleta Manual\ R. Feitosa et al. col.”, ( DZUP) GoogleMaps   .

Remarks. Polana (V.) feitosai   sp. nov. is most similar to P. (V.) grossii   in having the forewing with darker veins ( Fig. 26 View FIGURES 23–35 ) and the style with the apex rounded and a small dentiform process ( Fig. 33 View FIGURES 23–35 ). However, the new species can be easily separated by the aedeagus with apodemal processes narrow with a rounded subapical dorsal lobe ( Fig. 34 View FIGURES 23–35 ) (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   ).
