The morphology of the immature stages (eggs, larvae and pupae) of the Ponerine ant Ectatomma edentatum Roger, 1863 is described. Larvae had three instars during the post-embryonic period of development, without evident morphological differences except for the width of the cephalic capsules. The mandibles have a tooth in the three instars. Hairs are present since the first instar, uniformly distributed on the larval body, and did not vary in length in the three instars.
