The ecology of selected species of spiders (Araneae), harvestmen (Opiliones), and the neglected tropical order Schizomida, alien to Europe, is discussed. Their geographic origins and pathways of introduction, by transportation with goods, are similar to other predatory terrestrial arthropods. Occurrence in buildings (synanthropy) is a prerequisite for range expansion in many arachnid species. Thelytokous parthenogenesis facilitated spread of a few spider, harvestman and schizomid species outside their native range. Both prey generalists and specialists (woodlice-eating Dysdera crocata and ant-eating Zodarion rubidum) are among species successfully expanding their range. Alien arachnids include individual species belonging to many different families. We stress the absence of true invasiveness of alien arachnids in Europe. Some unusual adverse effects of alien arachnids were recorded, such as pollution of buildings and clogged car fuel system ventilation tubes. Frequency of painful biting and threat to native biota are low. © 2011 International Organization for Biological Control (IOBC). Source

The article presents a comprehensive list of the ants (Hymenoptera: Formicidae) of Peru. Distribution data for 592 valid names of species-group taxa in 76 genera and 12 subfamilies were collected through a bibliographical review. The most diverse subfamilies in terms of species richness are Myrmicinae (273 species/subspecies), Formicinae (86 species/subspecies) and Ponerinae (71 species/subspecies). The most diverse genera are Pheidole (86 species/subspecies), Camponotus (73 species/subspecies), and Pseudomyrmex (47 species/subspecies). With respect to geographic divisions, richness is highest in Madre de Dios (245 species/subspecies), followed by Huanuco (109 species/subspecies) and Cusco (104 species/subspecies). Regions in greatest need of additional survey work are Aycucho, Huancavelica, Moquegua and Tacna, from which virtually no information on the ant fauna is available. Copyright © 2015 Magnolia Press.
