Primary type information:
Primary type material: holotype worker. Primary type locality: Indonesia: Aru Is, “Aru 59” (A.R. Wallace). Primary type depository: OXUM.
A second specimen from Aru is present in OXUM, marked “Aru 56,” but the style of writing is different from the holotype’s label and the “56” appears to have been added separately, as it is in a different colour of ink (B. Bolton unpublished notes 1978).
