Abstract: Based on the external characters, genital structures, distribution, and
intermediate individuals from contact zones, the endemic species Amathuxidia
morishitai Chou & Gu, 1994 from Hainan, China is treated as conspecific
with A. amythaon (Doubleday, 1847) and is downranked to a subspecies of the
latter, i.e., Amathuxidia amythaon morishitai stat. nov. Meanwhile, two
subspecies groups of A. amythaon are recognized by morphological and genetic
evidence, termed amythaon-group (A. a. amythaon + A. a. dilucida (Honrath,
1884)) and annamensis-group (A. a. morishitai + A. a. annamensis Talbot, 1932)
with the latter group showing a deeper divergence than normal on a subspecific
level genetically.
