Trechus thomasbarri belongs to subgenus Microtrechus and is included in the Nebulosus Species Group by Donabauer (2005b). In addition to thomasbarri, 21 other species are included in this group, 18 of which occur in North Carolina and the rest in Tennessee.
Species Status:
The type locality is Haoe Lead in the Unicoi Mountains, Graham County, NC (Donabauer, 2005b). Donabauer named this species after Thomas Barr, whose work on Trechus in the Southern Applachians inspired his interest in this group

Technical Description, Adults/Nymphs:
Donabauer (2005b)
Comments:
"Distinguished from other species of the nebulosus-group by pale reddish colouration, small eyes, and prominently sharp basal angles of pronotum" (Donabauer, 2005b). Members of this genus generally show too little variation in pattern for standard photographs to be used to identify particular species.
Total Length [body plus wings; excludes ovipositor]:
4.1 mm (Donabauer, 2005b)
Structural Features:
As a member of subgenus Microtrechus, only the first segment of front tarsus is enlarged in males. This species is distinguished from other members of its species group morphometrically and by features of the aedeagus (Donabauer, 2005b).

Observation Methods:
Abundance/Frequency:
Donabauer (2005b) found only a single specimen, the type for this species
Adult Phenology:
Status in North Carolina

Comments:
This species is known from just a single specimen. Like other members of this genus, its highly restricted range and occurrence on a high elevation ridgetop makes it highly vulnerable to the warming and drying impacts of climate change.
