Platyarthridae

Platyarthridae is a family of woodlice, containing the following genera:

They are mostly less than long, and cannot roll into a ball. They have no lungs on the pleopods, and have very small compound eyes, with fewer than 10 ommatidia. They are similar to members of the family Trachelipodidae, which do have pleopodal lungs, although the lungs can be inconspicuous.
