Rekoa palegon  CRAMER, 1780
Family - LYCAENIDAE
subfamily - THECLINAE
Tribe - EUMAEINI
Rekoa palegon Tony Hoare
Introduction
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 8 Rekoa species, all of which are neotropical in distribution. Five of them - marius, abeja, stagira, zebina and bourkei are 'typical' hairstreaks - their undersides are plain brown, marked with red tornal spots on the hindwings, and the hairline streak from which the popular name "hairstreak" is derived. Another species meton has striking tiger-stripes, and a 'cat's eye' mark on the hindwing. The remaining two -  palegon and malina, have a series of suffused dark lines on the undersides. Males of all Rekoa species have iridescent blue uppersides. Females are brown with only a vague pale blue sheen.
Rekoa palegon is distributed from Mexico to northern Argentina.
