Figure 32. — Juania byssifera, new species: 32, ventral view of male genitalia with left 

 harpe and aedeagus removed; 32a, aedeagus. 



Male genitalia (slide 10709): Costa of harpe terminating in long 

 curved process; cucuUus broadly triangular, fleshy; sacculus elongate, 

 triangular, terminating in nearly straight, digitate, sclerotized 

 process. Anterior edge of vinculum deeply excavated. Gnathos 

 stout, curved, asymmetrical, less than twice as long as uncus. Uncus 

 broader posteriorly than basally. Aedeagus moderately long, slender, 

 armed with terminal hook. 



Type: Masatierra: El Camote, 600 m. (Jan. 9, 1955). 



Described from the unique male type. The clear-cut uninterrupted, 

 longitudinal stripe at once separates byssifera from other members of 

 the genus. The genitalia of byssifera place it with those species 

 having a vinculum with deeply excavated anterior edge and it is 

 probably nearest chiloma. It is separated from chiloma by the costal 

 process of harpe, slender extension of sacculus and the longer, more 

 slender aedeagus.
