Primary type information:
Primary type material: holotype worker. Primary type locality: Indonesia: Bachian (= Bacan I.) “Bac” (A.R. Wallace). Primary type depository: OXUM. Primary type specimen: CASENT0901344.
Type notes:
1) Donisthorpe, 1932c: 461, cites 1 worker in OXUM (confirmed by Bolton (unpublished notes) 1978). 2) A supposed syntype in NHMW does not appear to be from the same series as the holotype.
