PL mean corresponds to that of the topotypic population of C. ulkei. 
The Whitetop Mt. sample EW/PL mean also corresponds to that 
of topotypic C. ulkei and not the topotypic C. appalachianus sample. 
This size overlap demonstrates the clear value of using the distinct 
and less variable features of the aedeagus. Because of these size 
similarities some female specimens may be difficult to indentify. Lo- 
cality records for these two species in their zone of overlap may be 
treated with certainty only when males are present. 
Etymology. The name refers to the Appalachian region in which 
the beetle is found. 
Distribution. The species has roughly a linear range of 480 miles 
along the Appalachian Mts. from Madison County, Alabama north- 
eastward to Pocahontas County, West Virginia (Map 2). It is 
known from a few intermediate areas in Virginia, Tennessee, and 
especially from North Carolina in the vicinity of Mt. Mitchell. One 
collection has been made in the Cumberland Plateau of Kentucky 
and one in the Shawnee Hills of Southern Illinois.
