[Donisthorpe, 1932c: 444, suggests that irritans may be the worker of diligens.] Current subspecies: nominal plus carensis, carinifer, cliens, croceomaculatus, curtus, fatuus, hongkongensis, inferior, melanogaster, pallidus, procax, sumatranus, tinctus.
 * agnatus. Camponotus agnatus Roger, 1863a: 137 (s.w.) SRI LANKA. Combination in C. (Myrmoturba): Forel, 1914a: 266. Junior synonym of irritans: Bingham, 1903: 353.

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.
