While I was moving some planks in my garden, Kapellen, Belgium, I found several funnel-web spiders (Agelenidae). As I lack the equipment to look at the genitals, I can only guess the species. I hope one of you (Juergen?) can confirm or correct my ID's, based on the general appearance of the spiders. Many thanks in advance!

Spider 1 (picture 1): Tegenaria domestica or T. silvestris (male)

Hi, Jeroen!

Spider 1 is either Malthonica (ex-Tegenaria) silvestris or a juvenile Malthonica (ex-Tegenaria) ferruginea. Depends on whether it was found in a forest under a stone/wood log etc. or in or at a building. So is spider 5, but more tending to M. ferruginea.

Spiders 2 and 4 are clearly Tegenaria atrica (unbanded legs).

Spider 3 is no Agelenid, it's a juvenile Segestria bavarica (Segestriidae).

About spiders 2 and 4: Kevin Lambeets (spider admin at Waarnemingen.be) sent me a message. He told me that T. saeva (very similar to T. atrica) has been discovered in Belgium. Hence, he advised to change the species to Tegenaria spec. Any comments on this?
