Xenotrachea albidisca

Xenotrachea albidisca


Diagnosis
. The species is much smaller than species with similar forewing facies, and the reniform element of the pattern formed by the stigmata is broadly white.

Taxonomic note
. Specimens from the Mulu area have less white on the forewing reniform mark than do those from Kinabalu. Kishida & Yoshimoto (1979) state that vesica cornuti range from one to four in number. In most Bornean specimens there is one long one with a very short one adjacent to it, the latter is absent in the lowland specimen dissected (slide 13971).

Geographical range
. India, W. China, Taiwan, Vietnam, Borneo.

Habitat preference
. The species was taken infrequently from 1620m to 2600m on G. Kinabalu and at 1780m (upper montane forest) on G. Mulu. Three rather small specimens were taken in the lowlands, at 180m on G. Mulu and at 250m on G. Api, both in lowland dipterocarp forest.
