Yes, integument - texture, not colour - defines chordate taxa. Classes, not individual families.

And if the general body plan you described were that of elongated creatures (as both I and Dinoman972 have pointed out, it isn't, except for an excessively inclusive definition of "elongated" which includes everything from barely "longer than a rugby ball" to extremely thin and serpentine), that could also define a taxon. As it does with Vermes. Which is a class.

Primary mouthparts aren't the most important features, no. But they are often used as criteria for separating families (as in the various chordate families which are defined as having mouthparts that aren't typical for their class).

All of your points support that Furia's description is, at best, that of a higher-level taxon, and its species should be split out across different families.
