Introduction
About 120 members of the cosmopolitan subfamily Polyommatinae occur in the neotropical region. Most are confined to the temperate grasslands of the high Andes, although a few species occur at much lower altitudes.
The exact number of Hemiargus species is uncertain due to differing opinions about the taxonomic rank of various races of hanno. Lamas only recognises 2 Hemiargus species i.e. hanno and ramon; and lists ceraunus, gyas, filenus, antibubastus, hanno, astenidas and bogotana as subspecies of hanno. The latest research seems to indicate however that there are at least 6 species i.e. martha, huntingtoni, ceraunus, hanno, ramon and another currently unnamed species from Peru.
Hemiargus ramon is believed to be endemic to Ecuador but it is possible that in time it may also be discovered in northern Peru.
