Spiders occurring in soils and fissured rocks were investigated using pipe traps. Four microphthalmic species, namely Hahnia microphthalma, Porrhomma egeria, P. microps and P. cambridgei were collected. Hahnia microphthalma is reported from the Czech Republic for the first time. The importance of collecting material by complex pipe traps (consisting of a perforated pipe and a set of removable cups) to record the depth distribution of spiders in subterranean habitats is stressed. The importance of the soil and fissure network formed by sandy marlite bedrock and of alluvial soils for the life of subterranean spiders is documented.

We present a subterranean amphipod from genus Niphargus collected in soil traps. Traps were set for sampling soil spiders in the inundation of the Včelínek Brook, Dyje River watershed, Czech Republic. Most likely, the species lives in a shallow subterranean habitat and has likely got entrapped into soil traps at elevated level of groundwater during two floods. In total 189 specimens were collected. The collected amphipods are small, slender and resemble species that were broadly classified to N. aquilex aggregate. Although damaged DNA does not allow more inclusive taxonomic and phylogenetic examination of the species, a comprehensive revision of 19 morphological diagnostic traits for 64 species from the aggregate indicates that these specimens should be treated as a new species, named Niphargus diadematus sp. n.

Cheiracanthium rupestre Herman, 1879, and Xysticus albomaculatus Kulczyński, 1891, both originally described from Hungary,are among the most rarely reported species of their genera in Europe. Here we report that both of these species have very close relationshipsto similarly uncommon species originally described from France at about the same time. The specimens currently consideredas Cheiracanthium rupestre turn out to be very closely related to, but distinct from, Cheiracanthium striolatum Simon, 1878. However,the original description of C. rupestre does not match these specimens nor any other known species of Cheiracanthium. We thereforeconsider C. rupestre a nomen dubium and suggest that all previous records of this species after the original description actually refer toCheiracanthium macedonicum Drensky, 1921. Xysticus albomaculatus, on the other hand, turns out to be a junior synonym of Bassanianabaudueri (Simon, 1877) syn. nov., expanding the range of this species considerably to the East and at the same time confirming that it isa genuine European species, rather than a recent immigrant from North America as previously suspected.
