Undescribed Cf Niobella Trilobite from Morocco

Description: I received this one in a recent shipment from Morocco. While I could readily tell it was an Asaphid, I was stumped as the any further assignment. In cases like this I turn to one of the most respected collectors of Moroccan trilobites and asked his opinion. He replied that he had seen a couple in the past, and that it is most likely a species of Niobella. This genus is known from North America and Europe but has not been described from Morocco to date. It comes as a part and counterpart specimen, with the positive to the LEFT.
