Hey Raf;
My first thought was Phrurolithus, which have a 'shiny' Opisthosoma with similar markings (the middle markings sometimes being joined to form a band like this -^-). They don't have conspicuous spinnerets, though.
This tip made me think of the Gnaphosidae, which contain some marked and also shiny genera. I thought of Aphantaulax, which looks a little like that and occurs in the south, but it doesn't fit. Now my best guess is Micaria, mostly because there are so many species in this genus, one of them *has* to be correct...
Surely I'll try this quiz again later, but most likely I won't find the answer and hence not post. But I'm super curious about the answers of the experts...
Regards,
Clemens
