The genus Antheromorpha is redefined and shown to comprise 11 valid species: Antheromorpha
miranda (Pocock, 1895), Antheromorpha
bistriata (Pocock, 1895), Antheromorpha
comotti (Pocock, 1895), Antheromorpha
festiva (Brölemann, 1896), Antheromorpha
harpaga (Attems, 1937), Antheromorpha
mediovirgata (Carl, 1941), Antheromorpha
minlana (Pocock, 1895), Antheromorpha
pardalis (Pocock, 1895), Antheromorpha
paviei (Brölemann, 1896), comb. n., Antheromorpha
rosea Golovatch, 2013 and Antheromorpha
uncinata (Attems, 1931). Three new synonymies are proposed: Antheromorpha
bivittata (Pocock, 1895) and Antheromorpha
melanopleuris (Pocock, 1895) are synonymized under Antheromorpha
miranda (Pocock, 1895), and Antheromorpha
orophila (Carl, 1941) under Antheromorpha
comotti (Pocock, 1895). Detailed descriptions and illustrations of fresh material from Thailand and Malaysia are given, especially regarding colour patterns which appear to be crucial for accurate species identifications. Two Antheromorpha species proposed by Attems are redescribed, based on type material. The genus is rediagnosed and a key and a distribution map are also provided. At least in Thailand, adult Antheromorpha
rosea have been found to occur every year only for one or two weeks in September or October, disappearing thereafter.
