Butterflies of the
Amazon and Andes
Family - LYCAENIDAE
subfamily - THECLINAE
Tribe - EUMAEINI
Satipo, Peru ©
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 currently 44 known Strephonota
species. Many have only very recently been discovered, and only 25
of them have so far been given scientific names. The most widespread
syedra and ambrax, all of which
are distributed from Mexico to the Amazon basin.
Both sexes of most species have dazzling metallic blue uppersides.
The undersides are greyish or pale brown, either marked with a
broken 'hairstreak' line similar to that of
purpurantes, or marked like strephon
and ericata with a conspicuous solid
hairstreak line extending from mid-way along the strongly bowed
costa of the hindwing.
is endemic to the eastern Andes of Peru.
