Descriptions

A very small species easily overlooked but nearly always present, and frequently abundant, in Sphagnum bogs and acid waters generally. James Murray (1911) refers to is "bizarre optic arrangement; one eye on the side of its nose and the other in the back of its neck" (i.e. one asymmetric frontal eye and one median cervical eye).
