Manubria of the trophi with lateral extensions on the outer side (see also images below). The triangles mark the duct of the retrocerebral sac (with red pigment spot) which is relative short in comparison to the duct of Itura aurita. Because of this the retrocerebral sac is located anterior of the trophi.
