Habitat/Ecology. This species was found in both primary and old/mature secondary forests in Singapore, including disturbed secondary forest fragments in urban or semi-urban settings. In primary forest, colonies were found in fallen twigs or in soil near bases of aged rotting wood. In old secondary forest, the ants were found nesting under bark of fallen rotting branches or logs, also on leaf litter. Numerous alates were collected from cultivated grassy patches and disturbed secondary forest fragments in urban and semi-urban settings, using malaise traps.

Remarks. The minor workers of P. clypeocornis are almost indistinguishable from those of P. hortensis . Species occurrence was therefore only confirmed where major workers were available, or when DNA barcodes (from alates and minors) matching the verified species were obtained (see Wang et al. 2018a).
