CICADELLINAE: PART 2. NEW WORLD CICADELLINI Soil 
chamber without sclerites. Ovipositor with second valvula expanded and bear- 
ing teeth beyond basal curvature, primary teeth widely spaced near base, 
slightly more closely spaced near apex, primaries bearing minute denticles 
which continue over areas between primaries, with dorsal anteapical denticu- 
lations before acute apex. Pygofer narrowed and subacute apically, with a 
number of macrosetae on posterior half. 
Specimens of Scopogonalia vary from sordid light green to darker green or 
yellowish-olive, to dark with paler green or yellow markings. All of the species 
have an apical black spot on the head. 
Specimens of Scopogonalia have been examined from Venezuela, Colombia, 
Peru, Bolivia, southern Brazil, Paraguay, and northern Argentina. The vena- 
tion of the forewings and the long connective are similar to Tylozygus Fieber, 
but the connective is subdivided in the latter, and the female genitalia do not 
support a close relationship. The long connective, the articulation of the 
paraphyses with both the connective and the aedeagus, and the form of the 
pygofer processes in Scopogonalia are similar to Plerogonalia, new genus, a 
relationship supported by the form and chaetotaxy of the female pygofer and 
to some extent by the form of the second valvulae of the ovipositor. Species of 
Plerogonalia are much larger and have no open anteapical cells. 
Small green or yellowish neotropical Cicadellini are likely to belong in 
Scopogonalia, Caldwelliola, new genus, or in Chlorogonalia ultima, n. sp. 
My interpretation of Cicadella interruptula Osborn rests on a male with an 
‘“allotype” label in CM. The specimen is darker than the female labeled 
“type” but probably conspecific. My interpretation of Tettigonia subolivacea Stal 
is based on a male in MHNP which was from the type-locality and agreed 
with a sketch I had made earlier of the female lectotype in RMS.
