Range and Identity
Thoburnia rhothoeca is recorded from upper Potomac toward Roanoke drainages, with a stated absence from the York system in the compilation. An older upper New River account includes a reported local loss. That dated statement is not treated as a current survey of all possible sites.
Habitat and Behavior
Adults inhabit rocky riffles and runs in creeks and small rivers with moderate to swift flow. Young occur in rocky runs and pools. Life-stage context helps explain why an observation in a pool need not contradict the adult flowing-water association.
Food and Life History
The upper reference is eighteen centimeters total length, while twelve centimeters is common. The checked summary does not establish an independent maximum body mass or detailed diet and reproductive sequence. Those facts are not inferred solely from sucker mouth shape.
Field Note
Keep age or size class, date and drainage with a record. These details preserve both the habitat distinction between young and adults and the historical context of restricted localities.
