Material not physically examined. Queens, FOCOL1632-1633 ( ZMHB) [types of Crematogaster millardi ] .

Literature. Viehmeyer (1916), Overbeck (1924) [both as C. millardi ]. Wang et al. (2018a).

Localities. Bukit Timah Nature Reserve; Bukit Timah Road; I-cube building ( NUS); Lower and Upper Peirce Reservoir; Pulau Semakau New Fragment; Pulau Ubin; Sungei Buloh Wetland Reserve; Sunset Way.

Habitat/Ecology. This species is associated mostly with young or mature secondary forests in Singapore, including abandoned plantation forest and other disturbed fragments in urban or semi-urban settings. These ants have also been found in mangroves, nesting in mangrove tree trunks or foraging on Thalassina (mud lobster) mounds.

Remarks. This species was first recorded from Singapore as types of ‘ C. millardi ’ (Viehmey- er 1916); the latter species was synonymized as a junior synonym of C. treubi by Hosoishi & Ogata (2012).
