Domahovski, Alexandre Cruz & Cavichioli, Rodney Ramiro, 2017, Six new Brazilian species of Polana (Varpulana) (Hemiptera: Cicadellidae: Gyponini) with key to males, Zootaxa 4244 (4), pp. 535-555 : 538

Polana (Varpulana) bahiensis sp. nov.

( Figs 4–15 , 97 )

Diagnosis. Forewing ( Fig. 7 ) with six black maculae. Style ( Fig. 13 ) with ventral protrusion short with apex serrated. Aedeagus ( Figs 14, 15 ) with atrial processes very slender and curved dorsally, as long as shaft; shaft with a very slender pair of processes at mid-length of shaft, as long as shaft.

Description (male). Length 6.3mm (n=3). Head ( Fig. 4 ) in dorsal view with median length approximately four-tenths interocular width. Other characteristics as in generic description.

Coloration. Head and thorax ( Fig. 4 ) yellow without maculae. Face ( Fig. 5 ) without maculae. Prothorax with proepimeron ( Fig. 6 ), with black stripe below pronotal carina. Forewing ( Fig. 7 ) yellow and most translucent toward apex with black maculae on: cross veins of discal cell, apex of anal veins and two smoky on near wing apex. Legs yellow.

Male terminalia. Sternite VIII ( Fig. 8 ) 1.9 times wider than long; posterior margin broadly rounded. Pygofer ( Fig. 9 ) 1.6 times longer than maximum height; dorsal margin with a short process at base; apex tapered and rounded; posterior margin ( Fig. 10 ), in ventral view, with slight protrusion near apex. Subgenital plate ( Fig. 11 ) 3.0 times longer than wide; apex tapered and subacute. Connective ( Fig. 12 ) T-shaped, with rami as wide as length of stalk. Style ( Fig. 12 ), in dorsal view, with outer lobe truncated; in lateral view ( Fig. 13 ), ventral protrusion short, about 1.5 times longer than its maximum width, apex serrated; blade the same height along its entire length, apical portion slightly curved dorsally, apex subacute. Aedeagus ( Figs 14, 15 ) with atrial processes very slender and curved dorsally, as long as shaft, somewhat enlarged near base, apex acute; shaft wider near base and slender at apex, with very slender pair of processes at mid-length of shaft, as long as shaft, with acute apex; shaft apex membranous, curved anterad and then posterad, without apical processes.

Female unknown.

Etymology. The new species name refers to the State of Bahia where the type-series was collected.

Material examined. Holotype male: " Brasil, Bahia, 10 Km NE \ Encruzilhada \ 15.483°S 40.824°W \ 830m 15.xii.2012 \ G. Melo & P. Grossi leg" ( DZUP) . Paratypes: 2 ♂, " Brasil, Bahia,\ região de Ilhéus \ 2008-2009 Malaise \ K. Nakayama leg." ( DZUP) .

Remarks. Polana (V.) bahiensis sp. nov. is most similar to P. (V.) pandara in having the atrial processes very slender and aedeagal shaft with processes at mid-length. However in the new species the shaft processes are as long as the shaft itself and in P. (V.) pandara the shaft processes are three times shorter than the shaft.
