Review of the Southeast Asian millipede genus Antheromorpha Jeekel, 1968 (Diplopoda, Polydesmida, Paradoxosomatidae)

Abstract. 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.
