Questidae
Description
Questids have a prostomium lacking appendages, followed by
a peristomium and a single achaetous segment. The trunk
segments often show secondary annulation, particularly in the
mid-body region. They have reduced parapodia and chaetae
emerge directly from the body wall in two bundles. Chaetae
include serrated capillaries, hooks with a subdental ligament
and trifurcate chaetae. A ventral muscular eversible pharynx
is present. The anus is surrounded by two lateral lobes.
The above description is taken from Glasby (2000).
