CICADELLINAE : PART I. PROCONTINI 155 



Female abdominal sternum VII slightly to considerably produced 

 with apex variable interspecifically. 



This genus apparendy ranges from Panama to southern Brazil and 

 Peru, but no specimens have been seen from Venezuela. A number of 

 the species are known from only one sex, making the construction of a 

 key impractical at this time. Deselvana is closely related to Rhaphinhinus, 

 Abana, and Omagua with which it shares the distinctive form of the 

 dorsal margin of the pygofer. It differs from Omagua externally by its 

 more produced head and in the male genitalia by the lack of the very 

 large gonopore that occurs in Omagua. It is readily distinguished from 

 Rhaphirrhinus by the lack of the threadlike apical head process in 

 Deselvana. Distinguishing characters for Abana are set forth in the 

 discussion of that genus (p. 150). 



The female lectotype of Deselvana simulans (Schmidt) agrees with the 

 illustration in figure 141, The genitalia of the male holotype of Z). 

 dorsivitta (Walker) agree with male genitalia in figure 143, except for 

 the presence of a moderate number of small spines on the pygofer which 

 were not present in the specimen illustrated.
