Abstract

The aim of this study was to investigate genetic variation and phylogenetic relationships of the Mineus group of
Mycalesis in peninsular Thailand inferred from mitochondrial and nuclear gene markers (COI, EF-1α and wingless). Seven
species and 214 individuals of the genus Mycalesis were collected in six provinces in peninsular Thailand. In this study, two
distinct seasonal morphs were found as wet season form and dry season form. Phylogenetic relationships based on combined
gene sequences indicated that the Mineus group of Mycalesis was monophyletic group. However, M. intermedia, and M.
perseoides might be species complex. Five haplotype patterns were observed in M. perseoides indicating that Chumphon
province was the origin of M. perseoides. Divergence time of the Mineus group in peninsular Thailand was 23.03 mya during
Oligocene period.
