CICADELLINAE: PART 2. NEW WORLD CICADELLINI BES. 
The known distribution of Chlorogonalia is southern Mexico, Guatemala, El 
Salvador, Costa Rica, Venezuela, Colombia, Ecuador, Peru and central and 
southern Brazil. Chlorogonalia is closely related to the genus Cicadella Latreille 
from which it differs only slightly. The first posterior tarsite has two rows of 
longitudinal, very small setae, none of which are paleate, in Chlorogonalia; one 
row of setae, some of which are paleate, and the setae of the second row 
longer in Cicadella. The rami of the paraphyses of Chlorogonalia are narrower 
than in Cicadella. Chlorogonalia is also near Draeculacephala Ball and Carneocephala 
Ball, from both of which it differs in lacking an anteapical plexus of veins in 
the forewing. 
My interpretation of Tettigonia coeruleovittata Signoret is based on an 
examination of the lectotype in NMV. Fowler’s delineata has been syn- 
onymized as a result of an examination of the lectotype of that nominal 
species.
