Material not physically examined. Unknown.

Literature. None. New record.

Localities. Mandai Road; Pulau Semakau.

Habitat/Ecology. Individual workers were found in Manis javanica (pangolin) stomach contents – the pangolin was roadkill found on Mandai Road. Exact origins of these C. wroughtonii specimens could not therefore

be verified, but might be postulated to be secondary forest distributed along Mandai Road. Alate queens were also collected in replanted mangrove forest on an offshore island landfill.

Remarks. Chronoxenus wroughtonii is currently known from Central, South and East Asia, and parts of Southeast Asia including the Philippines, while its subspecies – C. wroughtonii javanus ( Forel, 1909) , is known only from Indonesia (Java) (antmaps.org - accessed Jan 2022; Janicki et al. 2016). We compared the specimens with type images of both species and subspecies on AntWeb, and found greater similarities with C. wroughtonii . Hence, at the time of writing we consider the two queens to be C. wroughtonii , but this putative conclusion may be changed when more material of both species are made available for examination in future.
