My husband found this little fellow along a creek bank in Briceville, TN this evening (04/01/2017). Approximately 3″ in length. Am I correct in identifying it as Sigmoria Trimaculata?

Flat Backed Millipede

Dear John and April,
Alas, we have not the necessary skills to identify this Flat Backed Millipede to the species level.  It certainly might be
Sigmoria trimaculata (please note the first letter of the second word of the species name is lower case), based on this BugGuide image, but it also looks quite similar to this BugGuide image of the Appalachian Mimic Millipedes in the genus Brachoria.  According to BugGuide, the family Xystodesmidae contains many similar looking species.  You might be correct, but we cannot confirm that for certain.
