Immature stages of workers of Ectatomma edentatum Roger, 1863 (Hymenoptera, Formicidae)

Abstract

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.
