Idiochlora berwicki Holloway

Diplodesma berwicki Holloway, 1976: 62.

Diagnosis

The wings are centrally rather translucent, revealing the irregular grey bands of the underside.

The hindwing margin has a secondary ‘tail’ near the apex as well as the usual central one.

Taxonomic Notes

The translucence, grey banding and bidentate hindwing margin are also seen in I. xanthochlora Swinhoe (India, with similar taxa in Sulawesi and Timor, ssp. timida Prout (probably a good species)), but I. berwicki is larger with slightly narrower grey bands and more produced tails.

In the male genitalia the valves are much larger with the costal angle more distal.

The saccular process is longer, more slender and regularly curved, and there is no scobinate lobe just basal to its apex: this is a feature of typical xanthochlora.
