[1] It is classified under the order Nektaspida, and is a sister-group to the families Liwiidae and Naraoiidae.

The mouth plate (or hypostome) that sits on the belly-side of the cephalon is elongated and divided by a straight left-to-right suture.

The frontal portion is approximately square with two pointed horns that extend from the frontal margin to the sides (like in a capital T), the back portion is longer than wide with a round back margin.

The pair of relatively short antennas are implanted behind the horns of the hypostome and stick out to the sides.

There appear to be three pairs of limbs under the cephalon, carrying side branches with bristle-like gills (or setae).
