identification
What distinguishes basalis from other Chauliognathus species? I couldn't find any web images for comparison.

 
C. basalis
The black marks. Search for Chauliognathus in the upper right corner and view other C. species.

 
more species
I see that this one looks different than the two species shown in the Guide (marginatus and pennsylvanicus) but there are 17 additional species of Chauliognathus on the nearctic list. How did you rule out those ones in determining that this was C. basalis?

 
C.basalis
There are papers by Ruth and Stephen Bernstein on two Colorado species in The Southwestern Naturalist 43 (1):62-69, March 1998 and in The Coleopterists Bulletin, 50 (3): 297-300, 1996 with drawings. The one species C.basalis is found in the plains, the other C.deceptus is similar,but found in the foothills and mountains. C.basalis is reported to range from CO,KS to OK. C.basalis is the only species that I have seen in this area over the years.

 
range info etc.
Okay, thanks. I've added some of that info to the Guide page for future reference.

 
additional reference C. basalis
Salsbury, Insects in Kansas, p. 196, has a photo of C. basalis. (1)

I've added that reference to the guide page.
