Polana (Varpulana) vulgaris   sp. nov.

( Figs 76–96 View FIGURES 76 – 87 View FIGURES 88 – 91 View FIGURES 92 – 96 , 102 View FIGURES 97 – 102 )

Diagnosis. Pronotum ( Fig. 76 View FIGURES 76 – 87 ) with two elongate dark-brown maculae near posterior margin. Style ( Fig. 85 View FIGURES 76 – 87 ) with ventral protrusion of blade short with apex serrated. Aedeagus ( Figs 86, 87 View FIGURES 76 – 87 ) with slender processes arising on each side of shaft near base, apex bifid; shaft without apical or subapical processes, apical third translucent.

Description (male). Length 6.5mm, (n=5), female, (paratype) 7.5mm, (n=5). Head ( Fig. 76 View FIGURES 76 – 87 ) in dorsal view with median length approximately three-tenths interocular width. Other characteristics as in generic description. Coloration. Head and thorax ( Figs 76 View FIGURES 76 – 87 , 93–96 View FIGURES 92 – 96 ) brownish, in life ( Fig. 92 View FIGURES 92 – 96 ) green. Face ( Fig. 77 View FIGURES 76 – 87 ) without maculae. Crown ( Fig. 76 View FIGURES 76 – 87 ) without maculae. Pronotum ( Fig. 76 View FIGURES 76 – 87 ) in dorsal view, with two elongate dark-brown maculae near posterior margin; in lateral view ( Fig. 78 View FIGURES 76 – 87 ), proepimeron with black strip below pronotal carina. Forewing ( Fig. 79 View FIGURES 76 – 87 ) brown with black markings on: cross veins of discal cell, apex of anal veins, crossed veins of second and third apical cells and larger maculae usually on costal margin at mid-length of wing; a transversal darkbrown band on apical third. Legs brown.

Male terminalia. Sternite VIII ( Fig. 80 View FIGURES 76 – 87 ) 1.3 times wider than long; posterolateral corners rounded; posterior margin with middle portion slightly produced and rounded. Pygofer ( Fig. 81 View FIGURES 76 – 87 ) 1.8 times longer than maximum height; dorsal margin with short process at base; apex tapered and rounded; posterior margin ( Fig. 82 View FIGURES 76 – 87 ) in ventral view, with slightly produced protrusion. Subgenital plate ( Fig. 83 View FIGURES 76 – 87 ) 2.4 times longer than wide; oval; apex rounded. Connective ( Fig. 84 View FIGURES 76 – 87 ) T-shaped, with basal width as wide as length of stalk. Style ( Fig. 84 View FIGURES 76 – 87 ), in dorsal view, with outer lobe truncated; in lateral view ( Fig. 85 View FIGURES 76 – 87 ), ventral protrusion short, about as long as maximum width, apex serrated; blade with apical portion slightly curved dorsally and narrower than base, apex acute. Aedeagus ( Figs 86, 87 View FIGURES 76 – 87 ) with atrial processes as long as shaft, apex broad with acute dorsomedial tip; shaft with slender processes arising on each side of shaft near base, with bifid apex, external rami longer than internal rami; shaft sigmoid in lateral view, without apical processes; apex membranous.

Female terminalia. Sternite VII ( Fig. 88 View FIGURES 88 – 91 ) two times wider than long; posterolateral corners rounded; posterior margin excavated laterad of rounded median lobe. Pygofer ( Fig. 89 View FIGURES 88 – 91 ) 1.6 times longer than maximum height. First valvifer ( Fig. 90 View FIGURES 88 – 91 ) 2.1 times higher than long. First and second valvulae ( Figs 90, 91 View FIGURES 88 – 91 ) as in generic description.

Etymology. The specific epithet, vulgaris   (noun in apposition), was chosen because this is a very common species in the locality where it was collected.

Material examined. Holotype male: " Brasil, Paraná, S.[São] J.[José] dos\ Pinhais , 25°36'18"S \ 49°11'37"W 880m \ 09–23.ii.2012 malaise\ A. C. Domahovski leg." ( DZUP) GoogleMaps   ; Paratypes: 18 ♂, 15 ♀, same data as the holotype ( DZUP) GoogleMaps   ; 8 ♂, 6 ♀, same data as the holotype except 21.xii.2011 sweep ( MNRJ) GoogleMaps   ; 7 ♂, 10 ♀, same data as the holotype except 22.i.2012 sweep ( MZUSP) GoogleMaps   ; 8 ♂, same data as the holotype except 23.xi.2013 sweep ( DZUP) GoogleMaps   ; 1 ♂, same data as the holotype except 02–09.xii.2012 ( DZUP) GoogleMaps   ; 1 ♂, same data as the holotype except 30.xi.2011 ( DZUP) GoogleMaps   ; 1 ♂, same data as the holotype except; 23.xi.2013 ( DZUP) GoogleMaps   ; 1 ♂, same data as the holotype except 24.iii.2012 ( DZUP) GoogleMaps   .

Remarks. Polana (V.) vulgaris   sp. nov. is similar to P. (V.) bidens   and P. (V.) tulara   in the shape of aedeagus with sigmoid shaft, without apical or subapical processes and translucent apex. However, it differs in having the aedeagus with atrial processes unbranched apically and the shaft with basal processes bifid apically. The aedeagal shaft lacks processes at mid-length, as in P. (V.) bidens   and P. (V.) tulara   .

The coloration of some specimens can vary in intensity: more pigmented specimens ( Fig. 93 View FIGURES 92 – 96 ) have larger black maculae on the costal margin at the wing mid-length; less pigmented specimens ( Fig. 95 View FIGURES 92 – 96 ) have smaller black maculae on the costal margin and lack the transverse dark-brown band on the apical third; or ( Fig. 96 View FIGURES 92 – 96 ) without black maculae on the costal margin and transverse dark-brown band. The coloration of the holotype is similar to Figure 94 View FIGURES 92 – 96 and is the typical and most frequent coloration. The extremes, very pigmented ( Fig. 93 View FIGURES 92 – 96 ) and very light ( Fig. 96 View FIGURES 92 – 96 ), are less common. More than 100 other specimens, not included in the type-series, all from the same locality, were available for study.
