Lymantria (Lymantria) subrosea Swinhoe

Lymantria singapura Swinhoe, 1906, Ann. Mag. nat. Hist. (7), 17: 547.

Lymantria singapura Swinhoe; Holloway, 1976: 50.

Diagnosis

The fasciation of the male forewing is strong and even, the discal chevron conspicuous. The hindwing is diagnostically pinkish with a strong grey border: two specimens from mangrove in Brunei have the pink area of the hindwing more greyish but do not differ in genitalia. The female has similarly strong but more block-like markings on the forewing. The discal mark is a simple chevron: in the next two species it has additional elements distally.

Geographical Range

Sundaland, Lombok.

Habitat Preference

Most records are from lowland forest, including mangrove forest, but one specimen was taken at 1200m on G. Kinabalu.

Biology

The larva has been recorded from Pinus (Pinaceae) in Peninsular Malaysia (unpublished FRIM records).

Taxonomic note

L. singapura Swinhoe is treated by Schintlmeister (2004b: 91) as a subspecies of L. subrosea Swinhoe, with niasica Strand as a new synonym of singapura. Schintlmeister extended the range of singapura north to S. China and the N.E. Himalaya and further east to the Philippines and along the Lesser Sunda chain to Timor. He also indicated (fig 287) that it occurred on Seram, and the author has taken it in Sulawesi. The nominotypical subrosea occurs in Sri Lanka and the extreme south of India.
