Forty-eight species of Scydmaenidae have been
recorded in Canada and Alaska. Improvements in
the current taxonomic status and in the methods
and frequency of collection of the species should
greatly in:rease this number. Scydmaenidae tend
to be common locally, possibly following distributions
of the mites on which both the adults and larrrae
feed. They are found chiefly in wet mosses,
deep forer;t litter, decaying logs and tree stumps,
tree holes, sawdust piles, and compost; some species
are associirted with ants and caves.
LeCorrte (1852) and Casey (1897) described
most of the North American species of
Scydmaenidae, but these works included rlany synonyms,
and the higher classification was confused.
Marsh (1957) made major improvements for the
western North America fauna, and recently Franz
(1985) viewed Casey's North American gemera in a
worldwide perspective. The last publlication,
together with recent work by Suter and Newton
(personal communication), forms the basis of the
present arrangement.
