Polana (Varpulana) naja View in CoL sp. nov.

( Figs 44–59 View FIGURES 44 – 55 View FIGURES 56 – 59 , 100 View FIGURES 97 – 102 )

Diagnosis. Forewing ( Fig. 47 View FIGURES 44 – 55 ) with median black maculae on costal margin. Style ( Fig. 53 View FIGURES 44 – 55 ) with ventral protrusion of blade elongated. Aedeagus ( Figs 54, 55 View FIGURES 44 – 55 ) with atrial processes short and membranous; shaft elongated, curved dorsally with anteapical pair of spiniform processes at posterior surface.

Description (male). Length 6.3, (n=5), female, (paratype) 7.0mm, (n=5). Head ( Fig. 44 View FIGURES 44 – 55 ) in dorsal view with median length approximately four-tenths interocular width. Other characteristics as in generic description.

Coloration. Head and thorax ( Figs 44 View FIGURES 44 – 55 ) brownish. Face ( Fig. 43 View FIGURES 32 – 43 ) without maculae. Crown ( Fig. 44 View FIGURES 44 – 55 ) with two small rounded black spots behind ocelli, near posterior margin. Prothorax with proepimeron ( Fig. 46 View FIGURES 44 – 55 ), with a black strip below pronotal carina. Forewings ( Fig. 47 View FIGURES 44 – 55 ) brown with black markings on: cross veins of discal cell, apex of anal veins, and a larger maculae on costal margin at half length of wing; transverse dark brown band on apical third. Legs yellow.

Male terminalia. Sternite VIII ( Fig. 48 View FIGURES 44 – 55 ) 1.4 times wider than long; posterior margin broadly rounded. Pygofer ( Fig. 49 View FIGURES 44 – 55 ) 1.9 times longer than maximum height; dorsal margin with short process at base; apex tapered and rounded; posterior margin ( Fig. 50 View FIGURES 44 – 55 ), in ventral view, with a rounded protrusion. Subgenital plate ( Fig. 51 View FIGURES 44 – 55 ) 2.8 times longer than wide; apical third tapered; apex subacute. Connective ( Fig. 52 View FIGURES 44 – 55 ) Y-shaped, with rami shorter than stalk; stalk elongate. Style ( Fig. 52 View FIGURES 44 – 55 ), in dorsal view, with outer lobe small and rounded; in lateral view ( Fig. 53 View FIGURES 44 – 55 ), ventral protrusion elongated, approximately four times longer than maximum width, apex curved ventrally and serrated; blade elongated, same height along its entire length, apical third bent dorsally, apex with acute tip. Aedeagus ( Figs 54, 55 View FIGURES 44 – 55 ) with atrial processes short, elongated and membranous, one-fifth of shaft length; shaft elongated, flattened in lateral view and with apex wide in posterior view, an anteapical pair of spiniform processes arising from posterior surface on apical fifth, apex with membranous projection directed ventrally.

Female terminalia. Sternite VII ( Fig. 56 View FIGURES 56 – 59 ) 1.5 times wider than long; posterolateral corners rounded; posterior margin with broad median lobe, slightly more produced posteriorly than lateral angles, and with very small Vshaped notch at middle. Pygofer ( Fig. 57 View FIGURES 56 – 59 ) 1.6 times longer than maximum height. First valvifer ( Fig. 58 View FIGURES 56 – 59 ) 2.4 times higher than long. First and second valves ( Figs 58, 59 View FIGURES 56 – 59 ) as in the generic description.

Etymology. The new species name refers to the shape of the aedeagus in posterior view, which resembles an elapid snake of the genus Naja .

Material examined. Holotype male: " Brasil, Minas Gerais,\ Itamarandiba-\ aeroporto 09–16.II.2013 \ Malaise \ G. Melo leg." ( DZUP) ; Paratypes: 4 ♂, same data as the holotype ( DZUP) ; 1 ♂, " Encruzilhada BA \ Brasil IX-1975 \ M. Alvarenga " ( DZUP) ; 1 ♂, S.[São] Gonçalo Rio Abaixo ,\ MG (Est. Amb.\ Peti-Cemig) 10.V.2002 \ A.F. Kumagai col." ( DZUP) ; 1 ♂, same data except 14.VI.2002 ( DZUP) ; 1 ♂, same data except 05.VII.2002 ( DZUP) ; 1 ♂, same data except 30.VIII.2002 ( DZUP) ; 1 ♂, same data except 13.IX.2002 ( DZUP) ; 1 ♂, same data except 04.X.2002 ( MZUSP) ; 1 ♀, same data except 11.X.2002 ( DZUP) ; 1 ♂, same data except; 01.XI.2002 ( MZUSP) ; 1 ♀, same data except 06.XI.2002 ( DZUP) ; 1 ♂, 1 ♀, same data except 08.XI.2002 ( DZUP) ; 1 ♀, same data except 10.I.2003 ( DZUP) ; 1 ♀, same data except 24.I.2003 ( DZUP) ; 1 ♂, same data except 28.II.2003 ( MZUSP) ; 1 ♀, same data except 02.V.2003 ( MZUSP) ; 2 ♂, same data except 11.VII.2003 ( MNRJ) ; 1 ♂, same data except 27.VI.2003 ( MNRJ) ; 1 ♀, same data except 19.IX.2003 ( MNRJ) ; 1 ♀, same data except 19.XII.2003 ( MNRJ) .

Remarks. Polana (V.) naja sp. nov. is most similar to P. (V.) sapitanduva sp. nov. in having the aedeagal shaft, elongated and curved with a pair of short processes on the posterior surface. However, the new species can be easily separated from other species of Varpulana by the very short and membranous atrial processes and the aedeagal shaft with apex flattened in lateral view and wide in posterior view.
