Spilosoma thomasi Holloway sp. n.
Spilosoma procedra Swinhoe sensu Holloway, 1976: 4.
♂♂ 18-20mm (G. Api), 22-23mm (Kinabalu). The facies is similar to that of hosei except the hindwings are a brighter yellow, contrasting with the forewing, and the tornal black markings are somewhat narrower, particularly that posterior to vein CuA2. The male genitalia are very different, with a broad, quadrate base to the valve, terminating in a tapering, finger-like process. The species is named for Dr W. Thomas in appreciation of his assistance with the Spilosoma group.
