Superfamily Lymexyloidea
FamilyLYMD(YLIDAE ship-timberbeetles
J.M. Campbell
Thirt;'ssvsn species of Lymexylidae are known
around the world. Only one rare species occurs in
Canada. .\dults are found in decaying wood, on tree
trunks, or under bark. The Canadian species is
probably .introduced, since it also occurs in Europe
and was firrmerly very destructive to wooden ships.
The classifrcation of the family is now fairly stable.
Crorvson (1955) and Wheeler (1986) believe
that Lymexylidae is closely related to Cleroidea and
Cucujoidea. Arnett (1968) places the farnily near
Lampyridae, based on wing venation. Wheeler
(1986) revised the world genera and higher classifications,
including a study of the phylogerny, morphology,
and known biology of the genera.

Superfamily Cleroidea
Family TROGOSSITIDAE bark-gnawing beetles
Y. Bousquet
Trogossitidae includes 22 species in Canada and
Alaska. Most North American species are found
under the bark of dead trees, in logs, and in stumps;
a few species occur in fungi. The adults and larvae
of many species feed on wood-eating insects; others
feed on dercaying matter or fungi. Tenebroides mauritanicus
is a well-known stored-product pest that
feeds on grains and cereal products.
Barron (1971) has revised the trogositids of
North America. The species are divided into two
subfamilies, Peltinae and Trogossitinae.
