Dysaethria subflavida

The upperside is dark brown with strongly angled fasciae, particularly the forewing antemedial. The hindwing has a marginal pale fleck between the tails and another, smaller one by the more posterior tail. The underside is of a more ochreous yellow-brown.

Taxonomic notes. The facies indicates the species is related to D. moza Butler comb. n. (Japan) and allies in the Himalaya and Taiwan (D. suisharyonis Strand comb. n.). It is larger, with a yellower tinge to the underside. The male genitalia have the uncus broad as moza but with the paired processes differently shaped, the more basal pair broader. The valve has the setae centrally and more evenly distributed rather than divided into two fields with the setae in the larger, more distal field more robust. The aedeagus is narrower, with the cornutus slender rather than short, robust. D. suisharyonis has only the robust field of setae on the valves and the cornutus is larger. The female genitalia have a longer ductus and the two signa near the base of the bursa are more robust, more stoutly spined, well separate rather than united across a broad triangle of sclerotisation.

Geographical range. Java, Borneo, Peninsular Malaysia (FRIM colln).

Habitat preference. A single specimen has been taken at 1760m on G. Kinabalu.

Biology. The larva of D. moza was illustrated by Sugi (1987). It is stout, bluish white, with prominent setae and a ring of black spots (pinacula for the setae) round each segment, some linked by weaker longitudinal black lines. The larva of suisharyonis, illustrated by Chen (1997), is similar, but with the black spots more confluent, the dorsal ones forming a continuous row of crosses along the central part of the body.

The host-plants recorded in each case were species of Viburnum (Caprifoliaceae).
