book review: J.-P. Kim (2002): [Coloured spiders of Korea].

During the survey of epigeous spider communities in the Bavarian Alps (Germany, Upper Bavaria), three species of Erigoninae were recorded from Germany for the first time. Micrargus alpinus and Silometopus rosemariae are endemic species of the Alps, Panamomops palmgreni is endemic to the Alpine mountain system. For each species present knowledge on distribution, habitat and phenology is summarized. As Micrargus alpinus was described in 1997, faunistic and ecological data are still very poor. Niche differentiation between the closely related species of the Micrargus herbigradus-group is discussed.

The opilionid Amilenus auranticus from caves in Rhineland-Palatinate and Saarland/Germany (Arachnida: Opiliones: Phalangiidae)

In a survey of 1,5 years, the daily activity pattern of epigeic spiders was recorded in a xerothermic habitat in the Diemeltal near Marsberg. The correlation between vegetation-structure, daily activity pattern and the hunting type of the spiders is discussed.

The areal expansion of Argiope bruennichi (Scopoli, 1772) in Germany has been pretty accurately documented in the last few decades. From the early expansion phase around 1900, however, there exist only few detailed facts. The research of the egg parasites has caused discussion to determine whether or not early finds of the ichneumonid species Tromatobia ornata (Gravenhorst, 1829) can be used as proof of the occurrence of Argiope bruennichi. The larvae of this parasitoid are monophag so the existence of Tromatobia ornata without the parallel existence of the hostspider does not appear to be possible.

Observations on the prey of pholcids (Pholcidae)

Pseudicius epiblemoides (Araneae: Salticidae) in Central Europe. A new record of this rare south-eastern European species is presented which represents the northernmost and westernmost locality and the second one in Central Europe. A detailed description of its diagnostic characters is given.

Published data and unpublished communications show that the range of Astrobunus laevipes in Central Europe is much larger than previously believed. The present review extends the list of records to the German states of Baden-Württemberg, Hessia, Rhineland-Palatinate, Bavaria, Northrhine-Westfalia, Saxony, and Lower Saxony and provides a map of the present distribution in Germany. Furthermore, it lists new findings of A. laevipes in the Czech Republic and Hungary (Rakaca/Serehat Valley). Records of A. laevipes in Austria are not included in this review.

Quantitative, time-limited samplings in monthly intervals from June 1995 to August 1996, in combination with the measurement of carapace width of juvenile and adult spiders has revealed the life cycle patterns of the riparian wolf spiders Pardosa wagleri and Pirata knorri and showed the effect of floods on their abundance at the Isar River (Germany, Bavaria). Adults and juvenile spiders are heavily affected by floods but the populations of both species are able to recover quickly. The life cycles of both species are synchronized with the season and display a spring/summer stenochrony. P. wagleri shows a second reproductive phase in early summer. This reproductive behaviour supports the persistence of populations in this disturbed environment.
