Remarks. Type locality in Singapore. Despite not having been recorded from Singapore for more than a century since its initial discovery, Leptanilla havilandi has been firmly established as a valid species discernible from its congeners within Indomalaya (see: Baroni Urbani 1977c, Ito et al. 2001, Wong & Guénard 2016). The scarcity of specimens may be partly attributed to the species’ subterranean nature and minute size, which render it elusive and difficult to find.
