Material not physically examined. Unknown.

Literature. None. New record.

Localities. Pulau Semakau; Pulau Ubin; Sungei Buloh Wetland Reserve.

Habitat/Ecology. Male alates were collected from mangroves in Singapore.

Remarks. Specimens available for examination were all winged males collected using malaise traps, thus were not taxonomically verifiable by morphology, which requires other castes especially major workers. The males from the ZRC were identified to P. umbonata solely based on COI barcodes (313 bp), which were matched against sequences of known species on GenBank using BLAST. We cannot completely rule out the possibility of misidentification of source organisms to gene sequences on GenBank. This record will need to be revised should more material be made available in future to disprove this tentative COI-based species diagnosis.
