New Trechine Beetles 1 3 1 



were obtained during a study of electrophoretic variation in the isolates 

 of the vandykei group {yandykei, pisgahensis Barr, tusquitee Barr, haoe 

 Barr, bowlingi Barr and seven undescribed species). They represent only 

 2 of 18 previously undescribed Appalachian Trechus species obtained by 

 a sifting technique in 1982-1984 (Barr, in preparation). With four spe- 

 cies of Trechus, three of them endemics, Camp Creek Bald now joins 

 the list of eight other massifs in the Unaka region with endemic species 

 (see Barr 1979a:41). Trechus inexpectatus is the only species of the 

 uncifer group currently known east of the Asheville basin; morphologi- 

 cally it is closer to uncifer (Great Smokies) and satanicus Barr (Great 

 Balsams) than to the series of species morphologically clustered around 

 aduncus Barr (including talequah Barr, howellae Barr, toxawayi Barr 

 and coweensis Barr; see Barr 1979a for descriptions, illustrations, and 

 geographic ranges). Camp Creek Bald is shown on Figure 46 in Barr 

 (1979a) but is incorrectly labeled "Camptown Bald." The site lies at the 

 west end of a long ridge 1300-1500 m in elevation and about 10 km 

 long.
