Dysaethria flavida
(everetti form)

Dysaethria flavida
(typical form)


The facies, with purplish grey patches on a pale yellow ground, is unmistakable. The male antennae are serrate, lamellate.

Taxonomic notes. The taxon everetti was based on more heavily marked material from Borneo and Sumatra. Since its description, material was collected from lower elevations in Borneo that matches the type specimen from Peninsular Malaysia more closely, being a slightly paler yellow and less heavily marked. Both forms are illustrated. No significant differences in the male genitalia were noted, but it cannot be excluded that two closely related species are involved.

Geographical range. Peninsular Malaysia, Borneo, Sumatra.

Habitat preference. One specimen referable to typical flavida was taken during the Mulu survey in lower montane forest at 1000m on G. Mulu, and two more from lowland forest (30-60m, 300m) in Brunei. The original specimens of everetti were from 1620-1930m on G. Kinabalu, with further singletons taken at 1790m on G. Mulu and at 1670m on Bukit Pagon. Only everetti is known from Sumatra, taken at a similar altitude.
