Ecpatia alleni Holloway sp. n.

♂♂ 10mm.

This is the smallest Bornean species, with the white basal area of the hindwing relatively small.

The forewing pattern is less clearly defined than in the previous seven species, dark, but generally variegated paler, the reniform being the most conspicuously pale marking, with the postmedial much more closely associated with it.

In the genitalia, the lobes of the peniculus are angled marginally, almost triangular.

There is a large quadrilateral plate extending the dorsal margin of the sacculus basally, and the apex of the harpe is accompanied by a much more prominent angle on the margin than in elliptica. The cucullus is relatively small, as in susanae, with short coronal setae at the margin.

The aedeagus vesica has a short cornutus, a sinuous accompanying sclerite, and a single patch of fine, short, deciduous spicules on the opposite lobe.
