Marumba spectabilis
(.65 natural size)


Diagnosis.
This is a more rufous brown species than the rest, with a very strong tornal loop to the forewing and extra, more irregular, weak fasciae between the ones characteristic of other species, There are conspicuous rufous orange areas at the torni of both wings on the underside.

Taxonomic notes. Sundanian material belongs to ssp. malayana.

Geographical range. Himalaya, S. China, Taiwan; Sundaland; Sulawesi.

Habitat preference. This may well be an exclusively montane species, being taken infrequently from 2100m to 2600m on G. Kinabalu and from 1000-1800m on G. Mulu. The Sulawesi race is found at lower altitudes.

Biology. In India (Bell & Scott, 1937) the larva is bright yellowish green above the spiracles, with yellow tubercles; below the spiracles the body is watery green with white tubercles, separated from the dorsal part by a bright yellow subspiracular stripe that is edged ventrally by brown, most intense on the thorax, weak or absent over the abdominal segments. The oblique bands are formed by yellow or red tubercles. The horn is bright green.

The recorded host-plant (Bell & Scott) is Meliosma (Meliosmaceae).
