Diagnosis. Coniform P 1 element with three subequally long and slightly recurved denticles all attached to the basal cup. Deep, teardrop shaped basal cavity. No clear anterior process.

Remarks. Te P 1 element of this species is very similar to the one of Urdyella unicorna n. sp. except for the lack of an anterior process and the fact that the single large cusp of Urdyella unicorna n. sp. is replaced by three subequally long denticles in Urdyella tridenta n. sp.
