Physical Description

Morphology

Body sturdy, elongated oval, rounded anteriorly and posteriorly, flattened ventrally, arched dorsally. The elytra are large, overlapping, covering the dorsum, thick, stiff, opaque. There are 11 pairs of elytra attached on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19 and 21. Elytral surface thickly covered with opaque rounded to conical microtubercles, especially thick on somewhat transverse areas in the middle of elytra and along borders with scattered globular and filiform micropapillae. The prostomium is bilobed, the anterior lobes prominent, each with a long frontal filament. The biramous parapodia have a shorter notopodia located on the anterodorsal sides of the longer neuropodia. Neuropodium diagonally truncate, with shallow notch on posterior lower side and deep notch on posterior upper side. Notochaetae with two rows of spines and blunt tapered and ?hairy? tips. Very numerous neurochaetae with slightly hooked tips and fine spiny rows on cutting edge. On some specimens, neuropodia of segment 13 differing by the presence of only 1-2 stout, reddish sabre like chaetae. 0/5 elongate papillae on segments 11-15.
