Marine isopods - Exosphaeroma diminutum
Myrtle Island, Northampton County, Virginia, USA
May 17, 2019
These were found in peat samples taken from one of Virginia's barrier islands. They would have spent the majority of their time underwater. Tried to take pictures at different focal lengths.

Moved tentatively
Moved from Typical Seapills.

This is a really poorly-known species that needs a redescription

looks like Cassidinidia
most likely Cassidinidia ovalis (family Sphaeromidae).

Why Cassidinidea?
From what I could find Cassidinidea is distinctive in the spharomatid fauna along the east coast for having very short uropod exopods (less than half as long as the endopod) while this indiviudal has about subequal uropod branches. I think I see some teeth on the exopod in some shots, which along with the smooth telson would make this S. quadridentatum?

Great question
But unfortunately, I am not qualified to say one way or another. Hopefully someone can chime in here.

Thank you
If anyone would know, it's you. Appears to be a new taxa for BugGuide?
