Almost all neotropical Theclinae species are placed in the Eumaeini.
The tribe is not particularly well represented in collections, so
until fairly recently a high percentage remained unstudied, and were
inappropriately filed away in the 'convenience' genus
Thecla. Many taxonomists have attempted
to rationalise the systematics of the Eumaeini, the most recent
being Robbins who published a revision in 2004, reclassifying the
taxa into 83 genera. Currently there are 1058 known species. Taking
into account their small size, secretive behaviour, and the great
similarities between many species, it is estimated that about
another 200 species probably remain to be discovered.
The genus Nicolaea comprises of about
40 species, variously distributed from Mexico to Paraguay and
Argentina. The males of most species have dark earthy brown
uppersides flushed with metallic blue. In females the blue areas are
paler, and confined mainly to the hindwings. The undersides of most
species are similar to the illustrated pyxis,
although some such as fabulla have the
band on the hindwing broken up into large irregular blotches.
Nicolaea pyxis is endemic to Colombia.
This species is found in rainforest at elevations between about
