microsctae, without processes. Plates separate throughout length or 

 fused basally, not extending as far posteriorly as pygofer apex, tri- 

 angular, with numerous dispersed microsetae. Style extending farther 

 posteriorly than apex of connective, with preapical lobe, rounded 

 apically, with lateral microsetae arranged serially behind preapical 

 lobe. Connective Y-shaped, with arms not widely divergent, stem 

 longer than arms and not strongly carinate. Aedeagus symmetrical, 

 with a pair of elongate slender processes or paraphyses arising basi- 

 ventrally, extending parallel to shaft, which is curved gradually postero- 

 dorsally; shaft with a pair of retrorse processes or an unpaired process 

 near midlength. Paraphyses — see above, under aedeagus. 



Female abdominal sternum VII produced and with apical margin 

 broadly rounded or slightly emarginate apically, 



Splonia is known only from Ecuador and Venezuela. The holoty^e of 

 Splonia acutalis Melichar, in the Signoret collection in Vienna, bears the 

 erroneous locality label "Senegal." The posterior femora are unusually 

 long for proconiinc leaflioppers. The generic affinities are unknown, 

 and Splonia appears to occupy a position well apart from other 

 proconiine genera.
