MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 43 



narrowed anteriorly, terminating in two curved points. Aedeagus 

 straight, armed with short, sharp, apical hook. 



Type: Masatierra: El Camote, 600 m. (Mar. 17, 1951). 



Described from the unique male type.

Figure 35. — Juania imperfecta, new species: 35, ventral view of male genitalia with left 

 harpe and aedeagus removed; 35a, aedeagus. 



Despite the damage to the forewings the species is so distinct it 

 merits description. This species also falls in the chiloma group but 

 can be distinguished from the others primarily by its symmetrical 

 gnathos. In pattern imperfecta somewhat resembles byssifera, but 

 imperfecta is a larger insect and the median longitudinal streak does 

 not retain its linear form all the way to termen as in byssifera. 



Juania imitator, new species
