"Spilosoma" hampsoni (Joicey & Talbot, 1916)
[Diacrisia hampsoni Joicey & Talbot, 1916 (nec Rothschild, 1914)] (holotype: Anggi Lakes, Arfak, in BMNH)
The species was originally described as Diacrisia hampsoni Joicey & Talbot, 1916 but the genus name Diacrisia Hübner, 1819 is only valid for the Palaearctic species sannio Linnaeus, 1758 and related species in Russia, China and Japan. Vladimir Dubatolov suggested that hampsoni is probably related to the species of the Sundanian genus Orhantarctia Dubatolov & Kishida, 2005, but he also stated that it almost certainly belongs to a new genus. Thomas Witt and Wolfgang Speidel will revise this species in the near future (personal comment).
Another Diacrisia hampsoni was described by Rothschild (1914) from India, actually belonging to Spilosoma. Since both species are presumably not congeneric there is no need for a replacement name for the junior hampsoni Joicey & Talbot, 1916.
STATUS: A local species, only few specimens are presently known. It seems to prefer mountainous areas. Its distribution probably continues along the Central Mountain Range.
