Vol. 105, No. 5, November & December, 1994 289 FUNGAL HOST RECORDS FOR SPECIES OF TRITOMA (COLEOPTERA: EROTYLIDAE) OF AMERICA NORTH OF MEXICO 1 Michael A. Goodrich 2 , Paul E. Skelley 3 ABSTRACT: A summary of the host fungi for the 1 1 species of North American Tritoma is pro-vided. Most species have clear host preferences, with varying degrees of specificity. Life histories are discussed, including a comparison of larval and adult host relationships. In 1991, we published a comprehensive list of the host preferences of the Erotylidae of America, north of Mexico (Skelley, Goodrich & Leschen 1991). During the past three years, as a result of recent fieldwork in preparation of Part III of our "Illinois Erotylidae", a large amount of additional host data has been collected for the genus Tritoma, including additional larval rearings. These data, together with that reported earlier, are presented here. This list reflects the current classification of host fungi. Members of the genus Tritoma Fabricius feed on a variety of macro-Basid-iomycetes. Adults are often found in numbers on fresh basidiocarps and some-times several species of adults are found on one basidiocarp. The duration of the three larval instars is brief in all species which have been reared. Pupation occurs in the ground adjacent to the host. All species reared transformed to adults without an extended quiescent period in either larval or pupal stages. The adult stage appears to be the longest lived. As noted in our earlier study (Skelley et ai, 1991), museum specimens have been of limited value in this research. Thus the majority of the records presented here are based on our recent fieldwork and rearing studies. RESULTS Data from 3,634 specimens are included in this paper; 1,808 of these are from collections made by the authors since 1991. In the following list of host fungi for the genus Tritoma north of Mexico, beetles are listed in phylogenetic order according to Boyle (1956) and by their currently accepted names. See Boyle (1956) and Goodrich & Skelley (1991) for lists of Tritoma synonyms. 1 Received May 3, 1994.
