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.
There are 17 known Ostrinotes species.
Many have only recently been discovered, and only 9 have so far been
given scientific names. The most widespread are
halciones, both of which are distributed across most of the
The males of all Ostrinotes species are
chocolate brown on the upperside, with a brilliant royal blue sheen
across the hindwings and lower half of the forewings. In females the
blue areas are a paler sky blue. The undersides of all species are
greyish or pale brown, marked with a broken hair streak line similar
in contour to that of halciones.

adults are more easily observed than those of many other hairstreaks
due to their larger size. They are usually encountered as singletons,
settled on the foliage of bushes or saplings in forest-edge habitats.
