Gnaphosoidea
Drassodes sp.
As Gnaphosoidea a group of families of the Real spiders ( Araneomorphae ) is summarized. This superfamily is not yet widely established in the scheme of arachnids. A common feature is mainly the very flattened and mostly oblong- oval rear pair of eyes. Little is known about the way of life and system of most of the over 2000 species. After further research, the systematic delineation of this group and the currently summarized in her seven spider families could largely move.
Only representative of the family of the smooth belly spiders ( Gnaphosidae ) are common in Central Europe. The smooth belly spiders make with 116 genera, the largest family within the Gnaphosoidea represents the other, mainly the ground layer inhabiting families are:
- Gallieniellidae
- Lamponidae
- Trochanteriidae
- Cithaeronidae
- Ammoxenidae
- Prodidomidae
These groups ( with the exception of Cithaeronidae and Ammoxenidae ) their distribution area in Australia, Tasmania, New Caledonia and New Zealand, and some are probably in Australasia endemic. Your diffusivity appears to be very low, so that they could be perhaps interesting for the biomonitoring.
