Justification This species has a moderately small range, within which is often rare or local. It is likely to have declined owing to habitat degradation in the lower parts of its elevational range, and is therefore considered Near Threatened.

Range & population Calyptomena hosii is patchily distributed in Sabah and Sarawak, Malaysia and Kalimantan, Indonesia. It is apparently quite common in the Baram drainage, very common in Liang Kubung and recorded in upper Telen, but absent or rare on intervening mountains.

Ecology: It occurs in the upper zone of mixed dipterocarp forest on hill slopes, and in lower montane forest. Most records are between 600 and 1,220 m, occasionally up to 1,680 m.

Threats Forest loss in the Sundaic region has been rapid and widespread, and is likely to have affected the lower altitudinal range of this species. However, its presence in sloping montane forest suggests that it is not imminently threatened, although logging activities in these habitats are increasing.

Conservation measures proposed Conduct repeated surveys across the range to determine the magnitude of declines and rates of range contraction. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Protect areas of suitable habitat and safeguard against logging and other threats.
