Trechus (Microtrechus) luculentus wayahensis , new subspecies 
Figs. 15, 42 
Etymology. — From Wayah Bald, a prominent topographic feature near 
the type locality. 
Description. — Length 3. 9-4.4, mean 4.1 mm. Differs from T. 1. luculentus 
in having only four elytral striae and larger aedeagus, 0.84-0.95 mm long; 
differs from T. 1 . umcoi in having less prominent hind angles of pronotum, 
only four elytral striae, and smaller aedeagus. 
Type series. — Holotype male (AMNH) and 30 paratypes, ravine at 
head of Dirty John Creek, southwest slope of Winespring Bald (near 
Wayah Bald), elevation 4900 feet (1500 m), Macon County, North 
Carolina, 3 July 1969, T. C. Barr. 
Measurements (in mm). — Holotype male: total length 4.42, head 1.15 
long X 0.87 wide, pronotum 0.84 long X 1.15 wide, elytra 2.48 long X 
1.98 wide, antenna 2.11 long. 
Distribution. — In addition to the type locality, this subspecies is known 
from two other sites in Macon County, North Carolina: Berties Falls, 
near Wayah Bald, elevation 4000 feet (1200 m) ; and Tusquitee Bald, near 
the Macon-Clay county line, elevation 4000 feet (1200 m). Tusquitee 
Bald, part of the Tusquitee/Valley River mountains, is 7 miles (11.3 km) 
west of Wayah Bald across the Nantahala River valley. 
Discussion. — The occurrence of this subspecies in the Nantahala Moun- 
tains was first brought to my attention through the kindness of Dr. J. 
Manson Valentine, who gave me three females he had collected at Bertie 
Falls and Dirty John Creek in 1950. A single large female Trechus 
specimen which I collected on Tusquitee Bald in 1960 was earlier referred 
tentatively to T. schwarzi (Barr 1962:75), but this specimen properly 
belongs with T. luculentus wayahensis. Two other species of Trechus, T. 
barben and T. tusquitee , have been collected syntopically with T. wayahensis , 
but T. aduncus howellae and T. nantahalae, which also occur in the Nan- 
tahalas, have not. Trechus nantahalae is readily distinguished from T. 
luculentus by the smaller eyes, pale color, and obtuse hind angles of the 
pronotum; the other three species are conspicuously smaller. 
Trechus ( Microtrechus ) rosenbergi Barr 
Barr 1962: 89, Fig. 26. Type locality, Water Rock Knob, Haywood and 
Jackson counties, North Carolina; type deposited in USNM. 
Trechus rosenbergi is a large (4. 5-5.0 mm) species, comparable in size 
only to T. carolinae (Black Mountains) and T. novaculosus (central
