Male genitalia (slides 10695, 10698): Costal arm of harpe curved, 

 sharply pointed; apex of cucuUus rounded; terminal process of sacculus 

 short, bluntly pointed. Uncus narrow. Gnathos less than twice 

 the length of uncus. Aedeagus armed with a short, stout hook. 



Female genitalia (slide 10696): Genital plate strongly sclerotized, 

 narrowed at ostium. Ventral lip of ostium short, evenly rounded. 

 Ductus bursae sclerotized for short distance before ostium. Inception 

 of ductus seminalis at junction of membranous and sclerotized parts 

 of ductus bursae. 



Figures 36-37. — Juania imitator, new species: 36, ventral view of male genitalia with left 

 harpe and aedeagus removed; 36a, aedeagus; 36b, ventrolateral outline of uncus and 

 gnathos; 37, ventral view of female genitalia. 



Type: Masafuera: Quebrada de las Casas (Jan. 16, 1952). 



Described from the type male, 5 cfcf and one cT paratypes all from 

 the same locality with same date.
