Nyctemera muelleri Vollenhoven

Leptosoma muelleri Vollenhoven, 1863, Bijd. Dierke, 1: 41.

Nyctemera muelleri Vollenhoven; Roepke, 1957: 155.

Diagnosis

The male has a modified zone of creamy white scales on the rather expanded, crumpled hindwing dorsal angle. The dark borders of both wings contain white spots, absent in the next two species. All three species have the border of the forewing postmedial white band concave in the spaces; it is convex in all other Bornean Nyctemera.

Geographical range

Sumatra, Peninsular Malaysia, Borneo.

Habitat preference

The species occurs from the lowlands to as high as 2000m, never commonly, both in forest and disturbed habitats.

Biology

The moth is taken flying by day and comes to light at nights.

Taxonomic Note

The evergista‐group of Nyctemera has been revised by de Vos (2002). The range of muelleri has been extended northwards into southeast Asia. The group consists of an array of species that extends east to the Bismarck Is. These species are allopatric except for overlap between muelleri and the mainland Asian carissima Swinhoe, and the distribution pattern of the array is a variant on the theme discussed by Holloway (1987) and Holloway & Nielsen (1998).
