Formica irritans

Three worker syntypes in. One labelled “MAL 19.”, the other two “34 MALAC.” (both localities = West Malaysia). In addition there is a single worker labelled “SAR. 1” which is probably the one mentioned from “Borneo (Sarawak) in the original description. I have placed this specimen with the syntypes.

Smith described this species twice in the same publication (pp. 55 and 58), based on the same specimens.
