| 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. |

| A comparative study is made of four chelicerate classes: Apatellata (Solifugae and Pseudoscorpionida), Arachnida s. str. (both groups of Uropygi, i.e. Holopeltida and Schizomida, Amblypygi and Araneida), Scorpionida and Xiphosura. Methods, principles and terminology, adopted in this paper, correspond with those of parts I -111 of the present series of comparative studies in Chelicerata. Special attention is paid to segmentation of the body, respiratory organs, orifices of coxal glands, mouthparts, and appendages. The evolution of these structures is studied, and the relationships of the chelicerate classes and subclasses are reinvestigated and discussed. |
