body ~ 6 mm, a zilion of them between dead leaves (on sunny places mainly), each step you make, you can see shortly 3-5 of them running away.

Hi!

Yes, also millions of them here at forest border. Young female of Pardosa lugubris group. Several species (separated only some years ago), which cannot be IDed after photo.

As far as I know Pardosa lugubris is a final species name ? Or not ?

What was originally described as Pardosa lugubris is really a group of 6 very similar species, of which Pardosa lugubris s.str. ("sensu strictu") is only one:

Pardosa lugubris s. str. (Walckenaer, 1802)
Pardosa alacris syn. Pardosa pseudolugubris (C. L. Koch, 1848)
Pardosa saltans Töpfer-Hofmann, 2000
Pardosa baehrorum Kronestedt, 1999
Pardosa caucasica Ovtsharenko, 1979 (only in south Russia)
Pardosa pertinax von Helversen, 2000 (only in Greece)

The two most abundant species are P. lugubris s.str. and P. saltans. The latter is more strictly bond to forests and forest edges and is - for example - here at the Teutoburger Wald more numerous than P. lugubris.
