Monomorium monomorium Bolton, 1987

Material examined. None available.

Material not physically examined. Unknown.

Literature. Tan & Corlett (2012).

Localities. National University of Singapore campus (Kent Ridge); West Coast Park.

Habitat/Ecology. Specimens identified as this species were collected from young secondary forests, recreational parks (mown grassland with trees and shrubs), and open grasslands.

Remarks. At the time of writing, this presumably non-native species is only known from Singapore based on one relatively recent literature record that could not be verified for taxonomic accuracy. Some specimens available in the ZRC were morphologically similar to M. monomorium sensu lato but could not be identified as the latter with confidence – these were at best designated as undescribed species of the M. monomorium group.
