Abstract:

Of the 28 families and over 1,300 species of terrestrial predaceous beetles the author was able to verify as recorded from the Columbia River Basin, only four families and ten species (less than 1% of the total species) were discussed in this report. The author believes that this low percentage is a commentary on our great ignorance of insects rather than an indication of the relative frequency of potentially threatened or endangered species within this functional group. Of the species discussed in this report, the author suggests that only three should receive immediate attention as potentially threatened and endangered species, based on existing information. Of these, Scaphinotus mannii is at the greatest risk, with Agonum belleri next and Cicindela columbica least immediately threatened. The last two may represent a "tie," dependent on the information that cicindelidists more familiar with Cicindela columbica than I am may possess. Adequate evidence exists to suggest that Cicindela arenicola, Ctenicera barri, and Nebria vandyke wyeast may well be threatened, but further research is required to make that assessment. Glacicavicola bathyscoides and Nebria gebleri fragariae do not appear to be threatened at this time, but may bear watching. Nebria gyllenhali lassensis and Nebria paradisi do not warrant any consideration for threatened or endangered status.
