Heptacondylus carinatus

Smith, F., 1858, Catalogue of the hymenopterous insects in the collection of the British Museum. Part VI. Formicidae., London: British Museum : 142

2. Heptacondylus carinatus . B.M.

Worker. Length 2 1/2 lines.-Dark fusco-ferruginous: closely resembling H. subcarinatus , but with thicker antennae and the joints shorter; the scape distinctly shorter, and not so slender at the base; the head proportionately larger, and much more strongly carinated; the thorax roughly carinated, and having longer and stouter spines; in other respects resembling H. subcarinatus .

Hab. Borneo (Sarawak).

Whether this can possibly be a form of H. subcarinatus , it is impossible to determine; the various differences pointed out appear to distinguish a distinct species.
