Odontomachus rugosus Smith, 1857a: 65 (w.) SINGAPORE. Indomalaya.

Primary type information: Primary type material: holotype worker. Primary type locality: Singapore: (no further data) (A.R. Wallace). Primary type depository: unknown. Type notes: A specimen labelled as type by Donisthorpe, 1932c: 447, in OXUM bears two locality labels, one of which is “SAR” (= Sarawak), and the other “Gilolo” (= Halmahera). As Donisthorpe points out this specimen “cannot be the type” as 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 Identity of the specimen appears correct; the labels may have been switched at some date after 1857 (Bolton (unpublished notes) 1978).
