Primary type information:
Primary type material: holotype worker. Primary type locality: Malaysia: Malacca, “MAL.” (A.R. Wallace). Primary type depository: OXUM.
Type notes:Smith, 1857a says “I have only seen a single specimen of this species”, and Donisthorpe, 1932c: 446, cites a holotype worker, but there is an alate queen specimen in OXUM, labelled “MAL. 12, Mt Ophir, 4000”, which bears a Donisthorpe type label; it is not type material.
