Neosho Midget Crayfish
This small crayfish is a subdued mottled brown or olive-tan, without bright markings but with a prominent black or dark brown band crossing the carapace near its junction with the abdomen. The body is stout, and the pincers are broad and powerful. Sometimes the pincers are tipped with orange or yellow. This is the only small brown crayfish that occurs in the Spring and Elk river systems. Other species in these drainages achieve a larger size, are more greenish, and have conspicuous black rings or whitish tubercles on their pincers.
