Geography-related sub-generic diversity within the Mediterranean trapdoor spider genus Nemesia (Araneae, Mygalomorphae, Nemesiidae)
Arthur E. Decae
- Three different male and female super-specific types are distinguished according to variations in the morphology of the bulb and spermathecae within the genus Nemesia Audouin, 1826. Plotting the distributions of these sexual types on a map of the Mediterranean indicates the existence of geography-related sub-generic diversity in which the Nemesia fauna of the eastern Mediterranean differs markedly from that of the western Mediterranean. While the eastern Mediterranean Nemesia fauna is highly homogeneous, the fauna of the western Mediterranean is very diverse. The eastern and western Nemesia faunae appear to overlap in the central Mediterranean. Efforts to relate the specific bulb types to the particular types of spermathecae described here were only partly successful.
Abundant and rare spiders on tree trunks in German forests (Arachnida, Araneae)
- The spider fauna active on the bark of trees in forests on eight sites in different regions in Germany was
investigated. Trunk eclectors at about 2-4 meters height on living trees were used in different regions of Germany
(SW Bavaria, Hesse, Brandenburg) between 1990 and 2003. In Hesse eclectors were also used on dead beech trees
(standing and lying). In this study data, mainly from beech (Fagus sylvatica) and spruce (Picea abies), from May to October
are compared – whole year samples (including winter) are only available from Hesse. A total of 334 spider
species were recorded with these bark traps, i.e. about one third of the spider species known from Germany. On
average, each of the eight regions yielded 140.5 (± 26.2) species, each single tree 40.5 (± 12.2) species and 502 (±
452) adult spiders per season (i.e. May to Oct.). The 20 most abundant species are listed and characterised in detail.
Six of the 20 species were not known to be abundant on bark, three prefer conifers and three beech/broadleaf.
Even in winter (December-March) there was a remarkably high activity on the trunks. However, only a few species
occur exclusively or mainly in winter. Finally, the rarity of some bark spider species is discussed and details
(all known records in Germany, phenology) of four of them are presented (Clubiona leucaspis, Gongylidiellum edentatum,
Kratochviliella bicapitata, Oreonetides quadridentatus). The diversity and importance of the spider fauna on bark in Central
Europe is still underestimated.

Neue Nachweise der Gerandeten Wasserspinne Dolomedes plantarius in Brandenburg (Araneae: Pisauridae)
Jason A. Dunlop
- The great raft spider, Dolomedes plantarius (Clerck, 1757), is a rare and endangered species in Germany and other European countries. Current data on its distribution and ecology are briefly reviewed. Five new (or overlooked) localities for this spider from the Spreewald-region of Brandenburg in eastern Germany are provided, together with an updated distribution map. One record, based on the authors’ own collections, is described and figured in detail, with the egg-carrying female discovered in reeds at the edge of a fairly large body of open water. Both direct and indirect protective measures for the habitats of this species in the Spreewald-region are recommended.

- The Ligurian leafhoppter, Eupteryx decemnotata Rey (Hemiptera: Auchenorrhyncha: Cicadellidae), is reported for the first time in North America (USA: Florida and California). Diagnostic characters for species identification, summary of hosts and damage, and U.S. known distribution are given.

A Preliminary Checklist, Classification, and Four New Country Records for the Elateridae (Coleoptera) of Ecuador
María P. Aguirre-Tapiero
Paul J. Johnson
- A checklist and classification of the species of Elateridae reported from mainland Ecuador are given. Anchastus boulardi Chassain, Cardiorhinus apicalis Golbach, Physorhinus marginatus Candèze, and P. sexnotatus Steinheil are reported from Ecuador for the first time. The recorded elaterid fauna of Ecuador is now represented by 140 species, 38 genera, and 9 subfamilies, which are low taxon richness numbers when compared to those of neighboring countries.
Rediscovery of Glauconycteris superba Hayman, 1939 (Chiroptera: Vespertilionidae) after 40 years at Mbiye Island, Democratic Republic of the Congo

- We report the rediscovery of the Pied Butterfl y Bat, Glauconycteris superba Hayman, 1939, 40 years after this species was last recorded. The new specimen from Mbiye Island, Democratic Republic of the Congo, is compared with the type specimens of G. s. superba and G. superba sheila Hayman, 1947 and a specimen from Matonguiné, Ivory Coast. The variation in the striking colouration of the pelage as well as in morphometric data is considered to be individual rather than geographic variation and we tentatively regard G. s. sheila as a synonym of the nominate form. Despite the wide distribution of this species in the tropical forest zone of West and Central Africa, only four specimens from four localities are known to date, which might indicate very specific habitat preferences. Contemporary land cover information around historic collection sites shows degraded landscapes. Given the highly uncertain area of occupancy of this species, we suggest changing the status of G. superba in the IUCN Red List of Threatened Species from “Least Concern” to “Data Defi cient”.
