FAMILY CERYLONIDAE
(Cerylonid beetles)
J.M. Campbell
Only about 400 species of this family of small to very small beetles are known for the world of which seven have been recorded from
Canada and Alaska. Most adults are collected from leaf litter, rotten wood and under bark. Hypodacne punctata is known from the galleries of
Camponotus ants and Murmidius ovalis occurs on stored products (Lawrence and Stephan 1975). Little is known about the feeding habits of the
larvae and adults although some are known to feed on fungal hyphae or spores and some larvae feed on a plasmodium of slime molds (Slipinski
1988).
Adults of this family are reasonably well-known taxonomically. The family was redefined and the higher classification revised by Sen
Gupta and Crowson (1973). The North American species were revised by Lawrence and Stephan (1975) and catalogued by Lawrence (1982b).
Slipinski (1989) is revising the higher classification of the family.
