Genus Parahololepidella Pettibone, 1969

Type species. Hololepidella greeffi Augener, 1918 .

Diagnosis. Body long, slender, flattened, with sides nearly parallel, tapered posteriorly, with numerous segments (up to 140 or more). Elytra numerous up to 50 and more pairs, on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 26, 29, 32, thereafter irregularly arranged on alternate segments, often asymmetrical, with different number on right and left sides. Elytra oval smooth, without tubercles and micropapillae; first pairs medium sized, usually covering mid-dorsum; following ones very small, leaving mid-dorsum and parapodia uncovered. Prostomium bilobed, subtriangular anteriorly, with or without distinct cephalic peaks, with two palps and three antennae. Ceratophore of median antenna in anterior notch; lateral antennae inserted ventrally.First (tentacular) segmentwithapairoftentaculophores inserted laterally to prostomium, with 1-2 aciculae and one slightly serrated unidentate notochaeta; facial tubercle prominent; mouth surrounded by two lateral lips, one dorsal with six–seven lobes, and one large ventral lip with 7-9 lobes. Second (buccal) segment with first pair of elytra, sub-biramous parapodia and long, tapering ventral cirri; without nuchal fold. Parapodia sub-biramous. Notopodia small, digitiform; notochaetae short, stout (not as stout as neurochaetae), tapering to blunt tips, unidentate. Neuropodia with longer rounded prechaetal lobes with subacicular digitiform processes; postchaetal lobes short, rounded; neurochaetae stout, with faint spinous regions, and slightly hooked, unidentate all of same type. Dorsal cirri smooth, with cylindrical, relatively long cirrophores and very long styles. Dorsal tubercles absent. Ventral cirri short, tapering. Nephridial papillae short, bulbous.
