Resumen

CIFUENTES-RUIZ, Paulina et al. Oligocene Scorpion and insects (Plecoptera and Coleoptera) from the Los Ahuehuetes Locality, Puebla, Mexico. Ameghiniana [online]. 2007, vol.44, n.4, pp.673-679. ISSN 1851-8044.

A scorpion prosoma, a plecopteran nymph, Euperlida parvicercifera Cifuentes-Ruiz gen. et sp. nov., and the elytra of an adult beetle (Coleoptera) are described from the Oligocene Coatzingo Formation, Puebla, Mexico. Specimens were found at the Los Ahuehuetes locality, Puebla, from where numerous plant remains have been previously described. A lacustrine paleoenvironment for these sediments is confirmed based on habitat of recent Plecoptera. This report represents the first record of Oligocene continental arthropods from Central Mexico, and the first for a fossil Plecoptera in this country. It is the first record for a Nearctic extinct genus of Perlidae.
