Two pairs of longitudinal dorsal muscular(?) ridges; outer pair shorter and very indistinct (difficult to discern in several specimens), abutting inners for entire length. Inner pair adjoined for majority of length, diverging only at distal prostomial margin. No other obvious prostomial ornamentation. Proboscis everted in two specimens, heart-shaped when fully everted, oval when partially everted; very lightly ridged. One specimen (NMW.Z.2010.037.0006) possessing an everted ‘buccal organ/tube’ between the everted proboscis and prostomium (see Discussion).

To be sure, such a band is faintly indicated on the other specimens from Bimini, but it is entirely lacking in the remaining specimens examined”. A pigment band was not observed on any of the Iranian material studied here. However, this area of the thorax does correspond with that which stained most strongly with methyl green.
