CICADELLINAE: PART 2. NEW WORLD CICADELLINI 39 
Female abdominal sternum VII with a narrow median notched posterior pro- 
jection. Genital chamber without sclerotization in dorsal membrane. Ovipositor 
with second valvulae as in Ortega truncatipennis (Signoret) (fig. 8, k, m, n). Pygofer 
with diagonal broad group of macrosetae parallel to posteroventral margin. 
Specimens belonging to the genus Aguana Melichar have been studied only 
from southeastern Brazil. Aguana species are rare in collections, and the above 
description has been based on seven specimens, only one of which was a female. 
Aguana is clearly related to Ortega Melichar, from which it may be dis- 
tinguished readily by the presence of paraphyses and apical aedeagal processes 
in the male and the more produced apical margin of sternum VII of the female, 
all of which differ from Ortega. 
The male genitalia of the holotype of Tettigonia sanguinans Walker agree with 
the illustrations of the Signoret-determined specimen of A. imbricata (Signoret) 
published here.

FIGURE 7 
Length of male 11.3-13.2 mm. Head with disk of crown longitudinally con- 
cave, with an M-shaped elevation bordering posterior margin, antennal ledges 
not carinate dorsally. Male pygofer with posterior margin broadly convex, 
pygofer process slender, slightly curved subapically, disk with a few macrosetae 
near middle of posterior half and another group parallel to ventral margin; plates 
extending almost as far posteriorly as pygofer apex in macerated specimens; style 
extending posteriorly farther than apex of connective; aedeagus narrowed 
somewhat abruptly anteapically in lateral view, with slender paired apical pro- 
cesses each of which is once-branched; paraphyses slender, almost straight, 
slightly divergent. Other structural characters of male as in generic description. 
Color of crown, pronotum, and forewings black, heavily spotted and vermicu- 
late with dull, dark red. Forewings with a conspicuous yellow spot in corium op- 
posite midlength of brachial cell, broadly and irregularly bordered with black, 
with an oblique dark reddish marking extending from outer anteapical cell pos- 
terolaterally to wing margin, broadly and irregularly bordered with black. Face 
black, heavily and variably marked with dull yellow or red. Propleura black 
lightly marked with yellow or red. Legs black. 
Holotype male, ‘‘Ribeirdéo”’ [Ribeira] Pires, Sdo Paulo, Brazil (E. Gounelle), 
November, 1898 (MMB), and two additional male specimens, both from Sdo 
Paulo (MMB and IZP).
