Type-species Evanirvana aurea Hill, 1973 View in CoL by monotype
Diagnosis. Medium-sized leafhoppers. Crown ( Figs 35, 39 View FIGURES 33−44 ) with median longitudinal carina complete extending from the anterior to posterior margin. Pronotum and base of clavus ( Figs 35, 36 View FIGURES 33−44 ) punctate. Forewing ( Figs 2 View FIGURES 1−8 , 16 View FIGURES 15−22 ) costal margin with supranumerary R branches along apical half. Subgenital plate ( Figs 4 View FIGURES 1−8 , 18 View FIGURES 15−22 ) narrow and elongated. Aedeagus ( Figs 8 View FIGURES 1−8 , 22 View FIGURES 15−22 ) with elongate dorsally curved pair of atrial processes; shaft with apical portion expanded with pair of lateral processes.
Coloration. Dull yellow ( Figs 11–13 View FIGURES 9−14 , 33–40 View FIGURES 33−44 ) with dark maculae on crown that may extend to pronotum ( Figs 35, 39 View FIGURES 33−44 ). Forewing milky hyaline; male with smoky median longitudinal band extending from the clavus to apical cells, absent in female ( Figs 2 View FIGURES 1−8 , 11 View FIGURES 9−14 , 16 View FIGURES 15−22 ).
External morphology. Head ( Figs 35, 39 View FIGURES 33−44 ), in dorsal view, distinctly narrower than pronotum. Crown ( Fig. 35, 39 View FIGURES 33−44 ) moderately produced anteriorly, expanded laterad anterad of eyes; coronal suture carinate and elevated towards apex; surface depressed between coronal suture and lateral margins of crown, texture with numerous longitudinal and oblique striations; anterior margin rounded or angled with distinct carina at crown-face transition; lateral margins, adjacent to eyes, raised and carinated. Frons, in lateral view ( Figs 36, 40 View FIGURES 33−44 ), oblique and slightly convex; inflated; with median longitudinal carina dorsally. Antenna moderately long; flagellum approximately one-fourth length of body. Antennal ledge carinate, in frontal view ( Figs 1 View FIGURES 1−8 , 13 View FIGURES 9−14 , 15 View FIGURES 15−22 ) narrow, flap-like; in lateral view ( Figs 36, 40 View FIGURES 33−44 ) slightly oblique. Gena broadly rounded, not emarginated below eye ( Figs 1 View FIGURES 1−8 , 13 View FIGURES 9−14 , 15 View FIGURES 15−22 ). Clypeus ( Figs 1 View FIGURES 1−8 , 13 View FIGURES 9−14 , 15 View FIGURES 15−22 ) rectangular; with parallel lateral margins; ventral margin straight or slightly arched.
Pronotum ( Figs 35, 39 View FIGURES 33−44 ) punctate; lateral margins carinate and strongly convergent anteriorly. Forewing ( Figs 2 View FIGURES 1−8 , 16 View FIGURES 15−22 ) hyaline; venation distinct; costal margin with supranumerary R branches along apical half; s crossvein slightly anterior to r-m 2; r-m 1 absent; three or more m-cu crossveins present; three anteapical cells (median one open or closed) and four apical cells; inner apical cell narrow and elongate; clavus with base punctate; appendix narrow, extending to second apical cell. Hind wing with veins R 4+5 and M 1+2 separated by short crossvein; crossvein m-cu short. Hind femur with macrosetal formula 2+1+1; tibia with AD row with two or three intercalary microsetae between macrosetae; tibia with AV row with 5–6 macrosetae restricted to distal half; first tarsomere with two parallel rows of small setae on plantar surface; apex with three platellae; second tarsomere apex with two apical platellae.
Male terminalia. Male pygofer ( Figs 3 View FIGURES 1−8 , 17 View FIGURES 15−22 ) slightly angulate posterodorsally; without lobes or processes; macrosetae restricted to apical area. Valve subrectangular; with sclerotized median line. Subgenital plate ( Figs 3–4 View FIGURES 1−8 , 17–18 View FIGURES 15−22 ) narrow; ventral surface with scattered fine setae. Connective ( Figs 5 View FIGURES 1−8 , 19 View FIGURES 15−22 ) T-shaped. Style ( Figs 5–6 View FIGURES 1−8 , 19–20 View FIGURES 15−22 ) with apodeme long; apophysis short and stout; apex hooked on inner side and with distinct long spine on outer side. Aedeagus ( Figs 7–8 View FIGURES 1−8 , 21–22 View FIGURES 15−22 ) with pair of long dorsally curved atrial processes; shaft depressed dorsoventrally, with pair of preapical lateral processes; gonopore apical.
Female terminalia. Sternite VII ( Fig. 9 View FIGURES 9−14 ) wider than long; posterolateral angles reduced. First valvula ( Fig. 10 View FIGURES 9−14 ) sculpturing pattern with dorsal area strigate and ventroapical area maculose. Second valvulae ( Hill, 1973: Figs C, D) with irregular teeth crowded apically.
Distribution. Brazil: Rio de Janeiro, Santa Catarina; Peru: Madre de Dios.
