CICADELLINAE: PART 2, NEW WORLD CICADELLINI 1025 
Thorax with pronotal width less than, or equal to transocular width of 
head, lateral margins convergent anteriorly, scutellum not transversely striate 
behind transverse sulcus; other thoracic characters and forewings as in 
Coronigonalia. 
Male genitalia: Pygofer moderately produced, with apex bilobate (excep- 
tion: S. remota, n. sp), with macrosetae occurring in a band parallel to and 
near posterior margin; pygofer process arising near middle of posterior margin 
or slightly more ventrally on posteroventral margin, extending mesally, or dor- 
sally and mesally and crossing median line. Plates very slender, gradually 
tapering to narrowly rounded apices, extending posteriorly a variable (inter- 
specifically) distance in relation to pygofer apex, with setae very small, uni- 
seriate or nearly so. Style extending posteriorly beyond apex of connective, 
rounded apically, without a lobe in basal half of shank. Aedeagus varying in- 
terspecifically, usually without processes. Paraphyses asymmetrical or absent, 
branched or not when present. 
Female (unknown in S. quepelana, n. sp., and S. remota, n. sp.) abdominal 
sternum VII deeply trilobate at apex, the median lobe broader and more 
broadly rounded apically than the lateral lobes. Genital chamber with a large 
median sclerite, oriented vertically in a transverse plane, contiguous with first 
valvifer on each side. Second valvulae each toothed through most of portion 
beyond basal curvature, the teeth widely spaced and each bearing numerous 
secondaries, apex acute and with dorsal anteapical denticles (much as in illus- 
tration of Graphogonalia clypealis, n. sp., fig. 810m). Pygofer acutangular dorso- 
apically in lateral view, with setae few, arising on apical half. 
Species of Stephanolla, new genus, have a red to orange band at the margin 
of the crown, as in Coronigonalta. 
The range of Stephanolla is southern Mexico, Nicaragua, Costa Rica, Pan- 
ama, and Ecuador. Stephanolla is related to Coronigonalia, new genus, from 
which it may be separated readily by the shorter male pygofer with the setae 
fewer and closer to the apical margin, by the more slender male plates, and 
by the trilobate abdominal sternum VII of the female, all of which differ from 
Coronigonalia. The male genitalia of Stephanolla are very similar to those of 
Mielsonia, new genus, but the styles of Stephanolla are more slender and 
elongate. Females of Nielsonia do not have the trilobed abdominal sternum 
VIL. 
The present interpretation of Tettigonia rufoapicata Fowler is based on a 
study of the male lectotype.
