Male Parcoblatta - Parcoblatta pennsylvanica - Male
Perry County, Pennsylvania, USA
The identifiers look just like pennsylvanica, but yet the entire coloration is different than all the pennsylvanica males in the colony. Any thoughts?

I actually had to coach my dad through the steps to take a macro photograph with my camera, since both my hands were restraining the roach. So credit for the photo really goes to my dad :)

Moved
Moved from Wood Cockroaches. Alright. Even though I am skeptical, I will believe it

I agree
That is part of the challenge in taxonomy- deciding which characters are reliable. The color pattern is generally good but not great in cockroaches. Characters related to mating (e.g. the structures/glands on the median segment) are considered more solid than others because they are related to the definition of what a species is. It is always possible that there are "cryptic species" within this group, and only time will tell if you are right- that the difference is significant. Until then, I think we should go with the median segment characters as the only reliable ones.
