What would be needed to get this IDd to species?

Species of Pseudosinella...
are IDed based on microscopic features, such as the shape and number of ocelli, shape of the unguis, shape of the unguiculus, chaetotaxy of the mouthparts (labium, labrum), etc

Well then I guess I'll have t
Well then I guess I'll have to get one of these guys under a dissection microscope. Shouldn't be too hard, they're very plentiful under the rocks in my yard.

A dissection microscope...
will be OK to prepare specimens on slides. But to see the details of eg the footcomplex you will need a more powerful microscope (magnification up to 600-1000x). Often it is also required to clear the specimens first eg in lactic acid otherwise the details will be obfuscated by tissue structures.
Need to add another important feature : the shape of the mucro (= terminal part of the furca).

Thanks for the advice,
I'll try to get those. I'm just a high school senior, and so I'd be doing this out of my school's biology lab, but the teacher should be able to help me with clearing the tissue and should also have access to a more powerful microscope. I'll do what I can to get shots of the defining features, and put it in this submission when I do.

Looking forward to see ...
the shots of the diagnostic features. Good luck!
