Many illustrations of Hermeuptychia butteries have 
been published, including photographs of most type 
specimens known, the habitus of all species (described and 
undescribed), and male genital structures. Both drawings 
and photographs are from a wide variety of localities and 
habitats of the American continent. Good quality data on 
the immature stages of at least three species are available, 
as well as data on hostplants, behavior, and ecology. e 
amount of data is overwhelming. e preparation of this 
notes has taken nearly ten years, and a supplement with 
the examined material will be timely published. Opinions 
on authority, typication, priority, synonymy, and hom-
onymy followed the provisions of the International Code 
of Zoological Nomenclature (ICZN 1999).

RESULTS
Nomenclature and synonymy of the species belonging to 
Hermeuptychia
e names hermes Fabricius and sosybius Fabricius have 
long been erroneously applied to other Hermeuptychia 
species (and to other taxa belonging to dierent genera) 
in a signicant number of papers and popular books. e 
synonymic citations for these two taxa in this article are 
not exhaustive.
