Philodromus
''Philodromus'' is a genus of philodromid crab spiders. Spiders in this genus are distinctively flattened. The more than 250 described species are distributed throughout the Holarctic region, with few species reaching into more southern regions. Some are found in certain parts of Africa, with sporadic species occurring up to Australia. Only one species (''P. traviatus'') is found in (northern) South America. 16 species occur in Central Europe.

Spiders Of Europe
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...
