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.
are 18 species of
all confined to the neotropical region. All have a similar pattern
of brown or black stripes radiating from the tornus of the hindwing
and terminating at points along the forewing costa. In many species
including separata and
togarna the stripes are well defined
and stand out in high contrast against a white ground colour. In
others such as dolylas the effect is
more subtle and serves to disrupt the outline of the butterfly,
rendering it invisible as it rests on soil, or among dead leaves.
Arawacus dolylas is found in Colombia,
Venezuela, Surinam and Ecuador.
This species is found in sunny areas along forest trails, at
altitudes between about 400-1200m.
