Ditch Fencing Crayfish (Shield Crayfish)
This small, tan crayfish has a pattern of paired blackish dashes along the surface of the carapace and abdomen. The pincers are narrow and cylindrical, with short, abruptly tapering fingers. The rostrum is broad, and without lateral spines or notches. The reproductive structures (gonopods) of males have long, slender tops, and the right and left tips cross each other diagonally. The areola (space in the middle of carapace) is very broad. Most other small crayfish found within the range of the ditch fencing crayfish--such as dwarf crayfish species and the young of other species--have a narrower rostrum, with lateral spines or notches near its tip. Many have the areola narrow or absent.
