New Species of Plethodon 7 



Ellis Branch of Spring Creek, near Springtown, in northern Polk 

 County, Tennessee, with no genetic evidence of current hybridization 

 between them (see below). 



At 28 of the 3 1 P. aureolus localities, white-spotted P. glutinosus 

 has been taken in sympatry. Highton (1972) pointed out that the name 

 Plethodon jordani teyahalee Hairston (1950) is available for the latter 

 form. The population at the type locality, Teyahalee Bald, Graham- 

 Cherokee County Une, North Carolina, is probably of hybrid origin, but 

 is much more like white-spotted P. glutinosus than P. jordani (Highton 

 1970). As shown below, this form occurs sympatrically with both P. 

 aureolus and P. glutinosus at locality 4, where apparent reproductive 

 isolation exists between all three forms. On the basis of this evidence, I 

 suggest that the white-spotted form should also be recognized as a dis- 

 tinct species, P. teyahalee. Its distribution and genetic relationships will 

 be discussed in a later paper.
