CICADELLINAE: PART 2. NEW WORLD CICADELLINI SET 
closed anteapical cells, their bases more proximal than claval apex, with four 
apical cells of which base of fourth is more proximal than base of third (ex- 
cept in amissa), without an anteapical plexus of veins, texture coriaceous ex- 
cept apically, without sculpturing; forewings of female in rest position ex- 
ceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1 or 
2:1:1:1, length of first tarsomere greater than combined length of two more 
distal tarsomeres and with two parallel rows of setae on plantar surface. 
Male genitalia: Pygofer strongly produced, posterior margin convex, with 
numerous macrosetae on posterior half, without processes. Plates short, not 
extending posteriorly nearly as far as pygofer apex, narrowed near midlength, 
with uniseriate macrosetae. Style with posterior extent compared to connective 
variable interspecifically, usually with a lobe near midlength (preapical in A. 
duodecimpunctata (Germar)). Connective variable. Paraphyses present, sym- 
metrical. Aedeagus short, much broader apically than at base, with a dorso- 
apical lobe developed to a degree that varies interspecifically, occasionally 
with apicoventral portion angular or with short processes. 
Female abdominal sternum VII varying interspecifically from slightly to 
moderately produced, apical margin from regularly convex (acute in amissa, n. 
sp.) to transverse and slightly emarginate. Dorsal membrane of genital cham- 
ber uniformly sclerotized, without sclerites. Ovipositor with teeth throughout 
dorsal margin of second valvula beyond basal curvature, the more basal teeth 
convexly rounded, teeth near midlength very broad, those near apex narrower, 
apex usually truncate, ventral margin of valvula usually convex. Pygofer with 
numerous macrosetae on apical half, or in a narrow group parallel to apical 
and apicoventral margin. 
Specimens of Amblyscartidia are red, brown, or (most commonly) black, and 
marked with yellow or gray spots (exception: A. juliacoides, n. sp., which has 
wings marked mostly with longitudinal lines.) All of the species except amissa 
have a pale transverse arc extending up the antennal ledges and at least part- 
ly across the disk of the crown. 
Amblyscartidia, new genus, is known only from Venezuela and southern 
Brazil. Amblyscartidia is similar in habitus, and in some characteristics of the 
male genitalia (for example the numerous setae of the pygofer, the form of the 
style and connective, the presence of paraphyses, and the broadened aedeagal 
shaft) to Dilobopterus Signoret where similar conditions are found among the 
large number of species of the latter. The development of the dorsal lobe of 
the aedeagus occurs also in Dilobopterus (although it occurs also in other 
genera not considered closely related). The form of the second valvulae of 
Amblyscartidia is also compatible with the suggested relationship. Amblyscartidia 
differs from Dzilobopterus in its symmetrical paraphyses, the broader hind- 
wings, and in that its posterior meron is concealed by the forewings in repose. 
Amblyscartidia is closely related to Paratubana, new genus (q. v. for dis- 
tinguishing features). 
My interpretation of Tettigonia albofasciata Walker is based on a study of the 
male holotype. I compared a male with the female holotype of 7. auriplena 
Walker, and have identified auriplena in the sense of these two specimens. 7. 
argentigutta is identified here in the sense of the female holotype. The genitalia
