It is difficult to get males of some species through the generic key, but the 
females are similar to Trichogonia and to Mesogonia evans: Young, but different 
from other Cicadellini. 
A number of specimens of Stehlikiana halticula (Jacobi) were collected on 
grasses in Chanchamayo, near San Ramon, Peru, by Juan Salazar and Carlos 
Ramirez. Specimens of S. crassa (Walker) were collected on carrots by A. Uni- 
garro, and on potatoes by M. Revelo in Pasto, Colombia. 
My identification of Tettigonia decorata Walker is based on an examination of 
the female lectotype. Signoret renamed this species as a result of secondary 
homonymy when he moved his Dilobopterus decoratus (1850b:285) to Tettigonia. 
Distant (1908a:524) restored the Walker name because the secondary 
homonymy did not exist then, an action not in accord with Article 59 of the In- 
ternational Rules. The lectotype of 7ettogonia crassa Walker, a specimen without 
an abdomen, has also been studied. 
I have studied the female lectotype of Tettigonia gryllula Breddin (fig. 42) and 
the lectotype of Tettgoniella halticula Jacobi (fig. 45). The female lectotype of 
Tettigonia latercula Breddin agrees with the present interpretation of that species. 
My interpretation of Tettigonia medusa Distant is based on an examination of 
the lectotype. I have not seen types of Tettigonia novemnotata Lethierry. Melichar’s 
identification of this species, which agrees well with the original description, is 
followed here. 
I have not seen specimens of the type-series of Tettigonia mirabilis Signoret. I 
have identified this species by comparisons of the series from Bogota, Colombia 
(RMS) with the original illustrations. The male genitalia, not illustrated, are 
very close to those illustrated (fig. 24) for Stehlikiana ramirezi, n. sp. 
My interpretation of 7ettigonia obsoleta Signoret is based on a study of the male 
lectotype (fig. 35), a series of specimens of both sexes from Rancho Grande, 
Aragua, Venezuela, and specimens from Villavicencio, Colombia. 
I have not seen a specimen eligible to be lectotype of Tettigontella obesula Jacobi, 
but my identification agrees with a male from Rioja, Peru, in Jacobi’s collection 
in Dresden, East Germany. I have seen only the female lectotype (fig. 43) of 
Cardioscarta perspicua Melichar. 
My interpretation of Cardioscarta perturbata Melichar is based on a study of the 
lectotype, and a male topotype. 
The illustrations of the abdominal sternum VII of the female were made from 
macerated specimens. The male genitalia of most of the species are so similar — 
that they are not very useful as specific characters.
