Narceus americanus (Palisot de Beauvois, 1817).
At least 14 Narceus species have been historically described, but most are now subsumed within the americanus/annularis complex.(2)
The Narceus americanus/annularis complex comprises two taxa of uncertain status that occur throughout eastern and central North America.(2).
Up to 11.5 cm — about twice as large as other North American millipedes.
Usually dark reddish-brown with red edges on each segment. The most commonly seen large millipede in its range (3).
Southeastern US, north to Ohio, and west to Texas (4).
