Figs. 22-24. Aedeagi of Trechus species, left lateral view: 22. T. schwarzi scopulosus, new sub- 
species, Craggy Dome, North Carolina. 23. T. schwarzi schwarzi Jeannel, Mt. Pisgah, North 
Carolina. 24. T. schwarzi saludae, new subspecies, Melrose, North Carolina. 
careful comparison of topotypic 77 schwarzi with similar populations in 
the Great Craggy and Black mountains north of the French Broad River 
valley. The latter proved to be taxonomically distinct and are described 
below. The nominate subspecies is thus restricted to populations of 
Pisgah Ledge, which is the eastern arm of the Great Balsams; 77 schwarzi 
has not been taken at other localities in the Great Balsams. 
My earlier description of 77 schwarzi (Barr 1962) was based on a 
paratype from Retreat and is essentially correct, but the aedeagal sketch 
which accompanied it (Fig. 7) applies to 77 s. scopulosus (described below). 
A female Trechus specimen from Tusquitee Bald, Clay-Macon counties, 
North Carolina, which I thought “may belong to schwarzi ” (Barr 
1962:75), is assigned to T. ( Microtrechus) luculentus wayahensis (described 
below), a species and subspecies now known to be abundant in the 
Wayah Bald area, scarcely 10 miles (16 km) from Tusquitee Bald. 
Nominate schwarzi is 3. 8-4. 4, mean 4.0 mm long. The hind angles are 
rather prominent and usually acute because of a relatively deep sinuosity 
in the lateral margins of the pronotum. Longitudinal striae of the elytra 
are rather shallowly impressed, the third through the sixth progressively 
obsolescent, the seventh absent. The aedeagus (1.31-1.39, mean 1.35 mm 
long) is weakly arcuate, with large basal bulb, a more or less straight mid- 
dle portion, and reflexed, attenuate, and knobbed apex.
