Gonçalves, Clayton C., Dietrich, Christopher H. & Takiya, Daniela M., 2019, Contribution to the tribe Pentoffiini (Cicadellidae: Evacanthinae) with descriptions of two new species and the male of Evanirvana aurea Hill, 1973, Zootaxa 4688 (2), pp. 271-281 : 276

Evanirvana tambopata sp. nov.

( Fig. 15–22 , 37–40 )

Diagnosis. Crown ( Fig. 39 ) with anterior margin acute; pale yellow with a X-shaped dark macula on anterior portion and triangular dark macula on posterior margin (extended over basal third of pronotum). Aedeagus ( Figs 21–22 ) with shaft depressed dorsoventrally; laterally expanded at apical fourth, with pair of long lateral preapical processes; apex narrow with slightly concave margin.

Description of holotype. Measurements (mm). Total length: 6.5.

Coloration. Pale yellow ( Figs 37, 38 ). Crown ( Fig 39 ) with an X-shaped dark macula on anterior portion and a diamond-shaped dark macula extending from posterior third of crown to basal third of pronotum. Forewing hyaline white ( Fig. 16 ) with a dark brown longitudinal band extending from mid-clavus to half-length of apical cells, narrow at base and widening towards the apex. Legs ( Fig. 38 ) pale yellow, except for black ventral surfaces of protibiae.

External morphology. Crown ( Fig. 39 ) with anterior margin acute. Coronal suture ( Figs 39–40 ) strongly elevated.

Male terminalia. Pygofer ( Fig. 17 ) approximately as high as long; macrosetae distributed only on posterior margin. Subgenital plate ( Fig. 18 ) extended beyond pygofer apex. Aedeagus ( Figs 21–22 ) with elongate, slightly sinuous, dorsally curved pair of atrial processes, shorter than shaft length; shaft depressed dorsoventrally, laterally expanded at apical fourth with pair of long lateral preapical processes, ventrally directed, about one-third of shaft length; apex narrow with slightly concave margin.

Female unknown.

Material examined. Male holotype, “ Peru, MD [Reserva Nacional Tambopata], Albergue \ Refugio Amazonas \ 12°52’30”[S]/ 69°24’35”[W]\ 231m, 03.xi.2016 \ D.Couceiro ”, ( MUSM) .

Etymology. The new species name is in reference to the type locality, Reserva Nacional Tambopata.

Notes. Evanirvana tambopata sp. nov. is easily distinguished from E. aurea by the shape of the maculae on the crown and pronotum, shape of anterior margin of the crown, forewing without supranumerary costal veins, and morphology of the aedeagus.
