Figure 28. — Juania abbreviata, new species: 28, ventral view of male genitalia with left 

 harpe and aedeagus removed; 28a, aedeagus. 



Male genitalia (slide 10689) : Typical of the group but with a stout, 

 overall appearance. Gnathos more than twice the length of uncus 

 Costal process of harpe fingerlike, apex rounded. Sacculus strongly 

 sclerotized, broad, ventral edge emarginate. Aedeagus armed with 

 a long, slender hook. 



Type: Masafuera: La Correspondencia, 1300 m. (Jan. 20, 1952). 



Described from the unique male type. The white hindwings, 

 with the contrasting fuscous terminal band, distinguish abbreviata 

 from all the other similar small species of Jminia. In male genitalia 

 it is nearest grisea but can be distinguished from it by the longer, 

 parallel-sided cucuUus, broader sacculus, and the more slender hook 

 of the aedeagus.
