From Smith, (1860) 
Head cordate; mandiblea porrect, tridentate; eyes round, placed anteriorly at the sides of the head, at the extremity of a broad, deep excavation; the antennae inserted in the excavation, into which they are received in repose; the flagellum 5-jointed; the scape three-fourths of the length of the flagellum; the ocelli placed in a triangle on the vertex, obsolete in the workers.
Thorax ovate, oblong, and attenuated posteriorly in the workers; the anterior tibiae: only furnished with a single spine at their apex. Abdomen with two nodes, the first attached to the thorax by a short petiole ; both are subovate, the second twice the width of the first; the abdomen subovate, and pointed at the apex.
The genus Strumigenys is doubtless closely allied to the Daceton of Perty ; these genera, with that of Orectoynathus, form a small group of ants, which appear to me to lead into the family of the Cryptoceridce; they agree with the latter `insects in having the antenna: placed at the sides of the head in a groove, into which they fall when in repose; they are also, like some species of Cryptoceridae, more or less ornamented with scales.
