Xenochroa annae

The forewings have fine striae throughout, an angled distal margin and diagnostic submarginal silvering that strengthens towards the tornus. The hindwings below have oblique, dark, crimson-red striae and bands on a pinkish ground.

Taxonomic note. The species was transferred to
Diehlea by Kobes (1997) but this placement is not supported. The male genitalia have more of the features of Calymera Moore and Xenochroa Felder, with a row of ten cornuti in the aedeagus vesica. The tymbal organs (Fig 233) are as complex as in these genera and have very broad apodemes. The female has a large but squat signum of the golf-tee type. The characters on balance indicate that transference to Xenochroa is preferable.

Geographical range. Peninsular Malaysia, Sumatra, Borneo, Sulawesi.

Habitat preference. The species is found up to 1618m. It is never common but has a high ecological amplitude, being found in dipterocarp forest as well as heath and coastal forest in the lowlands, and has been taken in secondary forest and cultivated areas. During the Mulu survey it was more frequent on the transect up the limestone G. Api to 1200m.

Biology. Yunus & Ho (1980) gave Eugenia (Myrtaceae) as a larval host-plant.
