Shield Crayfish (Ditch Fencing Crayfish)
This small, tan crayfish has a pattern of paired blackish dashes lengthwise along the upper surface of the carapace and abdomen. The pincers are narrow and cylindrical, with short, abruptly tapering fingers. The areola (space in the middle of carapace) is very broad. The rostrum is broad and lacks lateral spines or notches. The reproductive structures (gonopods) of males have long, slender tips, and the right and left tips cross each other diagonally like sabers.
Similar species: Most other small crayfish found within the range of the shield 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.
