enteric nervous system in other nematode

If "Enteric Nervous System" means the same thing as "Pharyngeal Nervous
System" (sometimes also called the "Esophageal nervous system" for extra
confusion, unless you're English in which case it's the "Oesophageal
nervous system"), the answer is yes: other nematodes do have one.  I've
looked at several soil nematode species: among them C briggsae,
Panagrellus, Diploscapter, and Oscheius.  By Nomarski they have pharyngeal
neuron nuclei in the same places as C elegans.  In C Briggsae and P
redivivus they function as neurons as tested by laser ablation.  I haven't
done any lasering on other species yet.

I would be interested to know if other nematodes are known to have an
enteric nervous system.
