CICADELLINAE: PART 2. NEW WORLD CICADELLINI 319 
Female abdominal sternum VII moderately produced with posterior margin 
broadly convex. Ovipositor with second valvula bearing numerous dorsal teeth 
beyond basal curvature almost to apex, the primaries bearing minute second- 
ary denticles, apex acute with minute regular anteapical denticles on dorsal 
and posteroventral margins. 
Specimens of Punahuana are dark orange with black markings. The range of 
the genus is Peru and Bolivia. The relationships between Punahuana and other 
genera are difficult to assess. The venation of the forewing, the simple form of 
the styles and the distribution of setae on the pygofer are somewhat like these 
features in Jrichogonia Breddin, but the marked differences in the female 
genitalia indicate that there is not a close relationship. The male genitalia 
have features in common with Backhoffella Schmidt in the discussion of which 
distinguishing characters are treated. 
In the illustration of the type of Punahuana brunneatula (Osborn) (fig. 259), 
the broader apex of the pygofer, as compared with that of dyscrita, n. sp., is 
misleading and peculiar to that particular specimen. The form illustrated for 
the latter species is common in both species.

Length of male 8.9-10.9 mm, of female 8.9-10.1 mm. 
Head with median length of crown varying from slightly more than four- 
tenths to slightly less than six-tenths interocular width and from three-tenths 
to almost four-tenths transocular width; surface of disk with lenticular im- 
pressions (holotype) or not. Other structural characters as in generic descrip- 
tion and like Punahuana brunneatula (Osborn), including male genitalia (fig. 
259) except that aedeagal processes are apical instead of anteapical. 
Ground color of dorsum, including the forewings, dark orange, crown with 
a basal and an apical median transverse spot (fused in holotype), usually a 
large spot occupying most of disk of pronotum, and a median spot in base of 
scutellum, black; clavus and inner portion of corium with dark streaks in the 
cells and an additional broader longitudinal dark stripe in corium and be- 
coming broader apically to the wide dark wing apex; face, propleura, and 
basal portions of legs concolorous with ground color of dorsum, tibiae and 
tarsi darker.
