This millipede is known from Johnson and Newton counties in northwestern Arkansas, USA.
The described specimens have clear side extensions on their body segments, with irregular orange spots internally.
The place where it was found in 1950 was an east-facing hillside in oak–hickory woodland.
At Steel Creek in Arkansas, two males were found in an area with oak, hickory and American beech among its main trees.
In the same specimens, the margins of the plate immediately behind the head are orange or pink.
An extinction-risk assessment has not been added yet.
