“…Biogeographic analyses show that the indigenous terrestrial fauna of the Azores is predominantly of Palaearctic origin, with hardly any of the indigenous species having exclusively Nearctic affinities (e.g. Mtquignon, 1946;Lindroth, 1960;Gama, 1988a;Borges, 1991). The centipedes are thus in accord with most of the other native taxa, in indicating that colonization of the archipelago from continents or islands to the east did occasionally occur without the aid of humans.…”

Until recently, only three species of Lithobiomorpha, Lithobius pilicornis Newport, L. lusitanm Verhoeff and Lamyctes fulvicornis Meinert were known from the Azores, and all could be plausibly considered as recent human introductions from western Europe. During expeditions in 1987 and 1989, investigating the fauna of caves and lava flows in the Azores, systematic sampling of invertebrates was undertaken on seven of the nine main islands in the archipelago. This led to the collection of three additional forms of centipede, two of which are considered as endemic and respectively cavernicolous and lavicolous subspecies of a widespread western Mediterranean species, Lithobius obscurus Meinert. The third represents an endemic subspecies of a different continental species, L. melanops Newport. Full descriptions of all three forms are provided. It is suggested that these two species colonized the Azorean archipelago naturally, and that the cave and lava‐dwelling subspecies of L. obscurus became differentiated in situ. Lithobius pilicornis may also have reached the archipelago naturally, but introduction by humans cannot be discounted. Niche relationships of the lithobiomorphs of the archipelago are considered, and the biogeographie and evolutionary history of the group in the Azores is discussed.

Azorean volcanic cave biodiversity is under considerable pressure due to ongoing threats of pollution, land use change, touristic activities or climate change. In this contribution, we present the IUCN Red List profiles of 15 cave-adapted arthropod species, endemic to the Azorean archipelago, including species belonging to the speciose genus Trechus (Carabidae), which is represented in Azores by seven species. The objective of this paper is to assess all endemic Azorean cave-adapted species and advise on possible future research and conservation actions critical for the long-term survival of the most endangered species. Most species have a restricted distribution (i.e. occur in one or two caves), very small extent of occurrence (EOO) and a small area of occupancy (AOO). A continuing decline in the number of mature individuals is inferred from the ongoing cave habitat degradation. The two troglobitic species of the homopteran genus Cixius are in great danger of extinction due to major land-use changes in epigean habitats above their known localities. We suggest, as future measures of conservation, the regular monitoring of the species (every five years), the creation of additional protected caves, the limitation of several aggressive activities around the caves (e.g. decreasing pasture intensification) and in some cases the creation of fences in the entrance of the most important caves.

“…8), algunos autores han optado por considerar que tal seda, aunque de menor tamaño, es una macroseda, así lo hace Gisin (1967) para P. gamae, mientras que Gama (1988) mantiene el criterio contrario para esta misma seda, cuando describe P. ashmoleorum. Aquí se ha optado por mantener los dos criterios a efectos prácticos y tratar de uniformizar todas las especies que presentan esta característica.…”

RESUMENSe describen dos nuevas especies Pseudosinella Schäffer, 1934 del grupo petterseni, con ejemplares de la colección de Federico Bonet: P. parattenuata sp. n. de los Estados Unidos y P. federicoi sp. n. de Argentina. Se proporciona una clave mundial para todas las especies que presentan un grueso diente en el empodio. Palabras clave: Collembola, Pseudosinella, Argentina, especies nuevas. ABSTRACTTwo new species of Pseudosinella Schäffer, 1897 (Collembola, Entomobryidae) of the petterseni group from the Bonet collection, with keys for its identificationTwo new species of Pseudosinella Schäffer, 1897 from the Bonet collection are described: Pseudosinella parattenuata sp. n. from USA and P. federicoi sp. n. from Argentina, both are established in the petterseni group, with specimens of Federico Bonet's collection. A key for the world species of the genus with a thick tooth in the empodium is given.
