There are jugulo-omohyoid lymph nodes located in the posterior triangle of the neck, but they are not referred to as "jugulodigastric." These nodes are found along the inferior belly of the omohyoid muscle, close to the internal jugular vein.
The digastric muscle is a muscle located in the neck, but it doesn't have a specific set of lymph nodes associated with it.
If you are unsure about a specific anatomical term, always refer to a reliable medical source or consult a medical professional.
