Spilosoma hosei

This species is similar to the next but somewhat smaller and distinguished by features listed in the description of the latter. Both can be distinguished from other yellow Bornean taxa by the strong tornal black markings on the hindwing and the widely separate antemedial and postmedial spots on the forewing dorsum. S. borneensis is some that similar but is a browner yellow with a reddish abdomen, and a sinuous brown band marking the forewing postmedial.

Taxonomic notes. This taxon is externally very similar to, and possibly merely a subspecies of the Sumatran S. procedra Swinhoe. But procedra has the valve apex rounded, not asymmetrically excavate, and a less extensive tuft of spines in the aedeagus vesica.

Geographical range. Borneo.

Habitat preference. The species is frequent in a range of lowland forest types. It is replaced at higher altitudes by the next species.
