A recent biodiversity survey on the terrestrial arthropods of the native forest, Laurisilva, provided a large set of standardized samples from various patches throughout the island. Out of the fifty two species recorded, approximately 33.3 % are Madeiran endemics, many of which had not been collected since their original description. Two new species to science are reported – Ceratinopsis n. sp. and Theridion n. sp. – and the first records of Poeciloneta variegata (Blackwall, 1841) and Tetragnatha intermedia Kulczynski, 1891 are reported for the first time for Madeira island. Considerations on species richness and abundance from different Laurisilva locations are presented, together with distribution maps for endemic species. These results contribute to a better understanding of spider diversity patterns and endemic species distribution in the

This work provides diagnostic characters for these species and, in particular, for the structure of male genitalia. The affinities with other known species namely their putative closest relatives, as well as ecological and biogeographical comments are also included. A key for the identification of the males of the Geocharis species found north of the Tejo River in Portugal is also provided. New chorologist data on other endogean carabids from Portugal are also included.

These changes have led to the increased homogenization of island biota and to a high number of extinctions lending support to the recognition of oceanic islands as major threatspots worldwide. Here, we investigate the impact of habitat changes on the spider and ground beetle assemblages of the native forests of Madeira (Madeira archipelago) and Terceira (Azores archipelago) and evaluate its effects on the relative contribution of rare endemics and introduced species to island biodiversity patterns. We found that the native laurel forest of Madeira supported higher species richness of spiders and ground beetles compared with Terceira, including a much larger proportion of indigenous species, particularly endemics. In Terceira, introduced species are well-represented in both terrestrial arthropod taxa and seem to thrive in native forests as shown by the analysis of spe...

Of the total 286 species identified, 81% were captured between 1999 and 2000, a period during which only 39% of all the samples were collected. On average, arthropod richness for each island increased by 10% during the time frame of these projects. The classes Arachnida, Chilopoda and Diplopoda represent the most remarkable cases of new island records, with more than 30% of the records being novelties. This study stresses the need to expand the approaches applied in these projects to other habitats in the Azores, and more importantly to other less surveyed taxonomic groups (e.g. Diptera and Hymenoptera). These step...

However, in Portugal there is still a lack of studies concerning this ecological group, particularly on faunistics. Here we present five new records of species from this country: Drapetes biguttatus (Piller & Mitterpacher), Mycetophagus quadriguttatus Müller, Orchesia micans (Panzer), Abdera bifasciata Marsham and Cicones pictus Erichson. All the species were collected in cork oak woodlands through two different techniques: baited pitfall traps in felled trunks and flight-interception traps in the canopies. On account of their saproxylic life-cycle these species represent important records for the Portuguese woodlands. More studies are needed to broaden the knowledge of this ecological group in Portugal, since they can be a valuable tool for forest biodiversity assessment and management programmes in the future.

The genus Thinobius Kiesenwetter is new for Portugal and Hesperus Fauvel is recorded for the first time from the Iberian Peninsula. The distribution of Quedius cobosi Coiffait, an Iberian endemic, is now extended to Western Portugal. All specimens were sampled in cork oak woodlands, in two different localities-Alcochete and Grândola-using two distinct sampling techniques.
