FIGURE 12. SEM micrographs <strong>of</strong> chaetae in Chitinopomoides wilsoni. Antarctic, ZMA V.Pol. 3166. A—fin-and-blade<br />
collar chaeta, B—1 st row <strong>of</strong> thoracic uncini, C—abdominal uncini, D—middle abdominal chaeta, E—“capillary” and<br />
Apomatus chaetae <strong>of</strong> 4 th thoracic chaetiger.<br />
THORAX: with collar chaetiger, and 6 uncinigerous chaetigers. Collar chaetae <strong>of</strong> two types: fin-andblade<br />
and hooded (limbate). Subsequent chaetae hooded, <strong>of</strong> two sizes. Apomatus chaetae from chaetiger 3<br />
onwards. Uncini along entire thorax saw-shaped, with 12 curved teeth, with blunt, apparently bifurcated peg<br />
(dental formula P + 12).<br />
ABDOMEN: abdominal chaetigers up to 62 at least (broken). Anterior uncini rasp-shaped, with peg and<br />
12 teeth when seen in pr<strong>of</strong>ile; posterior uncini with up to 5 teeth in a row. Chaetae flat geniculate. Short<br />
capillary chaetae and glandular pad present in about 12 posterior chaetigers. Pygidium bilobed.<br />
Size: length up to 24 mm. Width <strong>of</strong> thorax up to 0.8 mm. Branchiae and operculum accounting for 1/5th<br />
<strong>of</strong> entire length.<br />
Colour: no records.<br />
