Tamba kaingaran Holloway sp. n.

♀ 16mm. The general grey-brown coloration and the submarginal costal grey patch on the forewing are similar to those of rufipennis Hampson and hieroglyphica Hampson (Sundaland (ssp. malayana Prout) to Solomons, but not yet recorded from Borneo) but is distinguished from these and other Tamba by the regular sequence of fasciation on all the wings, including the linear nature of the pale hindwing submarginal. The forewing has curved, pale, thin, linear subbasal and antemedial fasciae, followed by a sequence of four darker, grey‐brown, more diffuse and irregular fasciae in the medial area, and the pale, linear angled postmedial. These dark medial and pale postmedial fasciae recur on the hindwing. The abdomen has a pale brown stripe dorsally, flanked by darker ones.
