FIGURE 260.—Punahuana dyscnta, n. sp. (a, ¢, f, from holotype; remainder from 
specimen from Callanga, Peru; setae not shown in ¢). 
Holotype male, “‘Sinchono”, Peru (DeLong collection, OSU). One female, 
Callanga, Peru (NCS). One female, ‘“Toungas de la Paz”, Bolivia; “1903- 
188”’ (BM). One male, Yungas de la Paz, Bolivia; one female, Marcapata, 
Peru; and one female, Cochabamba, Bolivia, ‘‘Germain’’, “‘Noualhier’’, 1898 
(MMB). 
Punahuana dyscrita is very close to P. brunneatula (Osborn) from which it may 
be separated by the characters in the key. In a series of mixed specimens, 
dyscrita may be separated by its less robust form.
