Ants of the Dominican amber Hymenoptera Formicidae 2 The first fossil army ants


, : Ants of the Dominican amber Hymenoptera Formicidae 2 The first fossil army ants. Psyche (Cambridge): 921: 11-16

The 1st fossil army ant, Neivamyrmex ectopus, sp. nov., is described from the Dominican amber, generally considered to be late Oligocene or early Miocene in age. Because of the extremely limited vagility of the Ecitoninae, and their apparent absence today from the West Indies north of St. Vincent, the presence of N. ectopus suggests a closer proximity of the Greater Antilles to the mainland during Tertiary times. Also, N. ectopus is phenotypically closer to species now living in Mexico and the southern USA than to the much richer Central and South American faunas.
