Fossils of Cephalotine ants are frequently encountered in Dominican amber. Of 22 specimens examined, 18 belong to species not known from the Cephalotine fauna of today. Four specimens could not be identified to the species level. Five species of the genus Zacryptocerus are described as Z. alveolatus n.sp., Z. integerrimus n.sp., Z. obscurus n.sp., Z. pseudo-aztecus n.sp., and Z. squamosus n.sp., together with four species of the newly raised genus Exocryptocerus (E. elevatus n.sp., E. serratus n.sp., E. truncatus n.sp., and E. jansei n.sp.). The Cephalotine fauna of the Carribean of today is poor in regard to the past and consists of only four well-defined species. This low number indicates a depauperation of the ant fauna and possibly the whole insect fauna in the Carribean. Most likely this depauperation was caused by a geological and climatical change before or shortly after the Flood.
