Primary type information: Type-material: holotype worker. Type-locality: Singapore: (A.R. Wallace). Type-depository: OXUM. Type notes: The specimen labelled as type by Donisthorpe in OXUM bears two locality labels, one of which is “SAR” (= Sarawak), and the other “Gilolo” (= Halmahera), whereas the type-locality given by Smith, 1857a: 65 is Singapore. This is the only Smith collection specimen of Anochetus rugosus detected in OXUM or BMNH. Identity of the specimen appears correct; the labels may have been switched at some date after 1857.
