This species qualifies as Endangered because it has a very small range, being known from just two mountains, where on-going forest destruction is reducing the extent, area and quality of habitat, and inevitably leading to a decline in numbers. It appears to be exceedingly rare on one of the mountains and, if there are no further records in the near future, it should be considered confined to one location and may require uplisting to Critically Endangered.

c.13 cm. Small, olive-brown and whitish babbler with moderately long, dark grey bill. Warm olive-brown upperparts, whitish underparts with relatively broad, contrasting dark streaking on flanks, ventral region suffused yellowish. Whitish eye-ring and conspicuous black "mask". Similar spp. Possibly confusable with other small passerines with streaked underparts (e.g. Muscicapa flycatchers), but distinguishable by combination of behaviour and dark mask. Voice Rather thin, high-pitched contact call notes consisting of tsip-tsip-tsip, often in trills. Hints Often encountered in groups, including mixed-species foraging flocks.
