This is a great resource for identifying North American Cafius
to species. Written in 1980 by H. E. Orth and Ian Moore.
The keys are straightforward, the descriptions well-written and detailed, and there are figures
at the end of the article...including large, good-quality, dorsal-view line drawings for each of the 13 species covered, and drawings of antennae for 5 species and aedeagi for all 13. While the emphasis is on the 10 species known (in 1980) from the west coast, it also includes a key to the five east coast species
, with briefer discussions of them.
I do wonder if there has been much change (e.g. additions or reorganizations) within the genus since 1980. If anyone out there knows of a more recent treatment of west coast Cafius
please let me know...particularly if it is accessible on-line. You can e-mail me, or better yet...leave a comment below with the salient info for all to access!
Nomina Insecta Nearctica
currently lists 10 species which are among the 13 treated in Orth & Moore's revision here. On the other hand, the ITIS website
lists only four species, one of which (C. nauticus
) isn't among the 13 in Orth & Moore (unless it's listed in synonomy somewhere in the article, and I missed it). I don't know if this means ITIS's authors adhere to a more recent (drastically lumped?) treatment...or if it's just some sort of oversight.
