The endemic Sulawesi amathusiine Faunis menado Hewitson (Lepidoptera, Nymphalidae) is divisible into two morphospecies

Abstract

Faunis menado (Nymphalidae, Satyrinae, Amathusiini), a butterfly endemic to Sulawesi, is separated into two morphotypes, one distributed in the north, the other in the south of the island. Morphological differences between their male and female genitalia and wing markings are as great as those seen between some other Faunis species. The ranges of the two morphospecies overlap, and some evidence suggests that they segregate locally as the result of differential responses to solar radiation intensity, and to altitude.
