Millipede roaming the earth

Millipede roaming the earth

Is this Narceus sp.? I'm new to looking closely at millipedes. Mt. Rogers Recreation Area, Virginia (USA)
Wait on a more experienced member to confirm or deny, but I'm pretty sure it's Narceus americanus-annularis. I'm not sure if that's the proper way to put the name or not, so hopefully they can answer that too
@Sadie11 I was reading this is a complex of species. I'm familiar with these confounding complexes in my work with salamanders. Sometimes you just can't tell the species apart until you put them all in a blender and sequence the DNA (which hardly seems worth it!)
Exactly! I do believe this is the N. americanus/annularis complex, but I'm still pretty new to millipedes. I have the pale form of these,and would love to be able to find some of these on a walk. I thought it was just tarantulas that were so confusing to ID, but apparently the problem is everywhere if it's salamanders too. Nobody seems to have simple anything anymore. All of the ""lessers, lavenders, caramels, etc" have added to the confusion.
This is what was known as N. annularis before the species were made into the complex. I think this form ranges from southern Canada down to Maryland and then N. cf. americanus takes over, but millipede taxonomy is pretty awful and there need to be more articles sorting out the differences between them.

I have a few cf. annularis myself and they are quite fun to have around although no eggs yet. The one in your picture is a male due to the hump on his 7th segment, if you didn't know that already.
@LawnShrimp So all I had to put in order to write it correctly was N. annularis? Nothing else? Just making sure because it really is confusing. Does the pale form have an easy way to write it, or would it just be N. americanus?
Nobody seems to have simple anything anymore

When I complained to a herpetologist friend about the impossibility if untangling the Desmognathus salamander genus, he replied, "You know, they can tell each other apart just fine, and they don't really care that it's hard for you." :astonished:

The one in your picture is a male due to the hump on his 7th segment, if you didn't know that already.

I didn't! I knew about checking the venter for gonopods, but didn't know you could tell from the top. Thanks!
Also, can you go by the hump on other millipedes, or just Narceus? My C. spinigerus has it too. I never knew you could tell that way.
@Sadie11 Yes, all individuals that have an enlarged 7th segment are male, though not all Spirobolid species have this hump to store their gonopods in.
