Revision of Trechus 
51 
near Devils Courthouse, Transylvania County; and summit of Whiteside 
Mountain, Jackson County, North Carolina. 
Discussion. — This subspecies commonly is found beneath carpets of 
moss on boulders. All collections have been made at relatively high 
altitudes, between 4700 and 5400 feet (1400 and 1600 m). Because of ap- 
parent altitudinal restriction there is, in my judgment, little or no gene 
flow between T. v. vandykei and T. v. pisgahensis at the present time. Syn- 
topic Trechus species include T. schwarzi schwarzi, 77 aduncus aduncus , and 
T. barberi.

Trechus (. Microtrechus ) vandykei: Barr 1962:77 (in part). 
Etymology.— From Haoe Lead, the type locality. 
Diagnosis . — A small species of the vandykei group, with non-sinuate 
pronotum sides, small, obtuse hind angles, four elytral striae, and a short, 
evenly arcuate aedeagus the apex of which is neither produced, knobbed, 
nor truncate.
