Justification of Red List category
This forest-associated species is listed as Near Threatened because it is suspected to be undergoing a moderately rapid decline (20-29% over three generations) owing to the extensive loss of lowland forests from large areas of the Sundaic lowlands.
Population justification
The global population size of this species has not been quantified, but it is generally uncommon to scarce (Wells 2007, Eaton et al. 2021, eBird 2024) in remaining tracts of lowland forest, which remain widespread, although much reduced in extent compared to three generations ago. Accordingly, its global population size is likely to be relatively large.
Trend justification
No direct population trend data are available for this species, however remote sensing data are considered a suitable proxy for this forest-dependent species. Over the past three generations, forest cover within its range reduced by c. 18-22% (Global Forest Watch [2024], based on data from Hansen et al. [2013] and methods therein). This species is commonest at lower elevations, where rates have been most rapid, and the species may be additionally impacted by forest degradation and fragmentation. Accordingly, rates of population reduction may be slightly higher than remote sensing data alone indicate. Accordingly, the rate of population reduction for the past three generations is set at 20-29%.
Philentoma velata is known from the Sundaic lowlands, occurring in south Tenasserim, Myanmar; peninsular and west Thailand; Sabah, Sarawak and peninsular Malaysia; Kalimantan, Sumatra and Java, Indonesia, and Brunei. It is considered extinct on Singapore, where it was last observed in 1879.
It inhabits broadleaf evergreen lowland and lower montane primary and secondary forest, as well as mixed deciduous forest, transitional forest and overgrown Albizia plantations, up to 1,700 m (Eaton et al. 2021). It feeds in pairs or small family groups in the middle and upper canopy, gleaning insects and sallying after them on short flights. It breeds in March-June.
The chief threat to this species is forest loss, which has been especially rapid in the Greater Sundaic bioregion due to timber extraction and the proliferation of plantations (chiefly oil-palm and rubber). These threats are thought to have driven declines of more than 20% over the past three generations. Forest fires associated with climate change may become more frequent over time, adding an additional pressure to this species including in protected areas. There is no evidence, however, that the species is heavily trapped.
Conservation Actions Underway
This species occurs in numerous protected areas across its range, which safeguard it from more precipitous rates of population decline. No specific measure is known.
Conservation Actions Proposed
Continue to monitor rates of population decline using habitat extent as a proxy. Protect more areas of lowland forest. Instigate longer-term monitoring at some sites to determine whether there are additional threats to habitat loss.
