I have actually posted these pictures on a native forum and was told that "The gonopods as I can see them are indicative of the Cambarus group. Based on appearance of ischeal hooks and gonopod tips they are form II (sexually incompetent), so gonopods will not be at their best value for species ID. Get them to molt into a form I (sexually competent) instar and you will have the ideal speciman to investigate."
I think I may post on the cray forum to see what they say there though. |
