This paper reports ten new species and one new status of Parasitiformes: Gamasina, found in Finland.
The described species are:
(Evans & Till, 1966) new status,
n. sp. and
Bai et al., 1995, is accepted as a
separate genus, including the species
n. sp. and
Bai et al., 1995. Identi±cation keys
are presented to clarify the taxonomic position of the new species in relation to the previously known
Parasitiformes, Gamasina, systematics, Scandinavian soil mites
Taxonomy, faunistics and ecology of soil-living Parasitiformes have been studied by
few researchers in Finland. Virtually all published data originate from certain ecological
experiments, mainly carried out in forest habitats (Huhta et al. 1979, 1986, 2005; Huhta, 1996).
Lehtinen (1987) studied the mesostigmatid fauna of ant nests, but covering only Uropodina,
Zerconidae and a few minor groups. The Finnish ‘PUTTE-Project’ (Research Program of
De±ciently Known and Threatened Forest Species), supported by the Ministry of Environment
in 2003–2007 (Juslén et al., 2008), rendered possible a comprehensive basic analysis of the
soil fauna (Acarina, Collembola and Enchytraeidae) of Finland. In the possession of the
Zoological Museum of Turku University there is a wide collection of Mesostigmata, mainly
collected by Dr. Pekka T. Lehtinen in the early 1980’s. Since then, the material has been
waiting for identi±cation, which became possible in the framework of the above mentioned
program. Uropodina and Zerconidae from the same material were identi±ed to species by P.T.
Lehtinen and deposited at the museum, but, with the exception of the ant-nest communities,
the data have not been published.
