Ethiopian (southern Africa). The South African genera are closely 

 alhed with Friseria. Sattler (1960) has shown that none of the 

 Palearctic species of the Gelechia complex are referable to the Lita 

 group with the exception of two species of Lita. Also, no Indo- 

 AustraUan or Neotropical gelechiid examined to date is a member of 

 the Lita group. 



Key to the Genera of the Lita Group 



1. Valva consisting of a simple lobe 2 



Valva consisting of a compound lobe or two or more lobes 4 



2. Valva very broad at base, apex narrow Araeovalva Janse 



Valva linear, slightly expanded apically 3 



3. Lobes of juxta separate (figs. 100, 103) Eudactylota Walsingham 



Lobes of juxta connected (at least by membrane) nearly to apex (fig. 66). 



Lita Treitschke 



4. Aedeagus linear, length more than 10 times maximum width . . Aria Clarke 

 Aedeagus stout or with expanded base 5 



5. Caudal setae of uncus scalariform Neodactylota Busck 



Caudal setae of uncus not flattened 6 



6. Valva consisting of two simple lobes, each linear and somewhat expanded 



distally 7 



Valva consisting of two or more lobes, lobes complex or saccal lobe very 

 broad basally 8 



7. Aedeagus broad basally, very slender on distal three-fourths; costal lobe of 



valva shorter than medial lobe Rifseria, new genus 



Aedeagus stout, narrowest beyond middle, apex somewhat expanded; costal 

 lobe of valva longer than medial lobe Sriferia, new genus 



8. Costal lobe of valva slender, simple; saccal lobe very broad basally, becoming 



narrow, then relatively slender to apex Schizovalva Janse 



Costal lobe of valva with medial or basal projections 9 



9. Uncus emarginate medially Leuronoma Meyrick 



Uncus even or produced medially 10 



10. Hook of gnathos curved before one half, then straight and gradually tapering 



to apex Parapsectris Meyrick 



Hook of gnathos curved at or beyond middle, abruptly turned just before 

 apex Friseria Busck
