has a marked difference in the relative length along chaetigers 1-3, with chaetiger 2 being the longest and often with a constriction in its posterior margin.This feature, however,may be misleading because the interparapodial body width is more or less the same along subsequent chaetigers.The most notorious feature is thus the elongated second chaetiger, and the fact that it is anteriorly expanded, its chaetae contributing to the cephalic cage, and the chaetiger becomes narrower posteriorly.
