Material not physically examined. Unknown.

Literature. Type – Smith (1857) [as Polyrhachis chalybeus ].

Localities. Jalan Kayu; Lower Peirce Reservoir, Forest B; Mandai mangrove; Sime Road; University campus (Bukit Timah).

Habitat/Ecology. This species is associated mainly with young secondary habitat of varying levels of disturbance, including waste woodland secondary forest fragments in urban or semi-urban settings, in Singapore. It is sometimes also found in mangrove back forest. Individuals were usually collected on trees or tree trunks.

Remarks. The holotype specimen depicted on AntWeb was inferred to be from Bacan island, Indonesia (based on specimen label ‘Bac’), however, in the original description of ‘ P. chalybeus ’, only two other type localities were given: Singapore and Malacca. It may be notable that an additional label on the holotype specimen reads ‘Mal-ca’, which might refer to Malacca, one of two type localities indicated in Smith’s (1857) original account.
