, which has an elongate rostrum, long neck and arched (concave) base. Nevertheless, the results of their morphometric analysis utilising all components of shape variation placed these uncini in the Type 2 category. It is likely that the uncini of the posterior body have a more typical Type 2 shape. As noted in the section on morphological characters, at least three other species show the combination of Type 2 uncini and early start of uncini occurring on poorly developed neuropodia. In addition, analysis of co-varying notochaetal characters by these authors provided further support for the grouping of this species with other species bearing Type 2 uncini.
