- Villa occulata was found in a bog in the province of Dalarna, Sweden in 2005 and 2006. Extended search for the species in 2007 showed it to be regularly present in similar mires in the same area. This indicates that the species is resident in Sweden and opens the possibility for further studies of its poorly known distribution and biology. The species seems to be confined to bogs which may explain why it has gone largely unnoticed. The paper summarizes the present state of knowledge.

Tidskriftsartikel (refereegranskat)abstract
- Pardosa pyrenaica sp. n. is described based on material from the Pyrenees (Andorra, France and Spain). This species belongs in the Pardosa pullata-group, members of which are characterised, inter alia, by having a tegular apophysis consisting of two membranously connected sclerites. Pardosa pyrenaica sp. n. and P. pullata (Clerck) share comparatively short legs, notably the first two leg pairs, in comparison to other species in the pullata-group. Moreover, the first two pairs of legs in these two species are furnished with an abundance of scopulate hairs (less developed in the female sex). Males of the two species differ notably in the shape of the embolus while the females differ by the course of the receptacula and usually by proportions in the shape of the epigyne although there is some overlap due to morphological variation. The restricted elongation in final instar legs and the abundance of scopulate hairs in the anterior two pairs of legs are associated with traits in the precopulatory behaviour, which is described for both species.

Fixation of Lycosa fidelis =. Pickard-Cambridge, 1872 as the type species for the genus Wadicosa Zyuzin, 1985 (Araneae: Lycosiadae), with a redescription of the species

Forskningsöversikt (refereegranskat)abstract
- The name Lycosa or Pardosa venatrix has been used since Simon in 1882 to denote a widespread Palearctic species. The nominal species Lycosa venatrix Lucas, 1846 was originally designed as the type species for the genus Wadicosa Zyuzin, 1985. It has, however, been recognized that the species long known as venatrix was misidentified: the species so named by Lucas is evidently not a species of Wadicosa. Therefore, we now fix Lycosa fidelis O. P.-Cambridge, 1872, the species actually involved in the misidentification, as the type species for Wadicosa. An emended diagnosis for the genus Wadicosa is given, as well as a redescription of W. fidelis. The presence of some hitherto unrecorded structures in the male palp is emphasized. A hypothetic view on the mating mechanism in W. fidelis is presented.
