Totolapa is one of the amber Lagerstätten from Chiapas, southwestern Mexico, which include the Simojovel and Huitiupán deposits. Despite the remarkable paleobiological heritage of Chiapas amber biota, the fossil record of ants from Totolapa has so far not been well studied. Based on exceptionally preserved specimens, four ant genera from the Totolapa amber deposits are reported in this paper, including Forelius, Azteca, Tapinoma, and Camponotus (Hymenoptera, Formicidae). Whereas the genera Azteca, Tapinoma, and Camponotus are previously known from amber quarries of Simojovel, this paper represents the first record of the presence of Forelius in Chiapas amber.
