The microtrichia of the dorsal surface of the metazonites do not appear to be set in sockets, so instead of setae they are direct outgrowths of the cuticle. They vary in size and distribution; the smallest microtrichia are densely arranged in rows on the anterior and posterior edges of the paranota. Larger microtrichia are found sparsely scattered on the anterior part of the metazonite, and microtrichia of similar size are densely arranged on the elevated parts and along the horizontal midline of each paranotum (

, 6). The largest and most prominent microtrichia are on the paramedian knobs. While the microtrichia, with their curved, spatulate shapes, appear welladapted for catching and holding soil particles, the particles appear to be held on mostly by a gummy secretion and could only be partially cleaned off using ultrasonics. The mixture of secretion, small soil particles and humic materials appears ropy. Scattered among the microtrichia are very small spherical objects that may represent this secretion, but no glandular pores could be detected even at high magnification under the SEM.

Curiously the median pair on the epiproct are much larger than any others, and can be easily seen with an optical microscope. They may have some special function.

, each family in which paranota-bearing species occur has the great majority of their species without them. These non-paranotal species often have the lateralmost two metazonital setae of each side set on prominent, horizontally projecting tubercles which give the rings something of a “flat-backed” appearance, and comparison of these with paranotal species suggest that the paranota develop by the extension of the outer part of the tubercles. Functionally, paranota are associated with the “litter-splitting” habit in which the paranota are used as wedges to get into narrow spaces between leaves and other debris in the litter (
