Main Features: The disc of this species has distally swollen plates bearing small conical stumps on their distal edges. The lateral arm plates are also swollen distally with similar cones or raised portions. The ventral surface of the disc is without tubercles apart from those on the distal edge of the plate adjoining the oral shield. Otherwise, all disc plates are strongly granular. There are 2 pairs of exposed tentacle pores, each with a single scale which does not cover the entire pore. There are only 2 ventral arm plates on each arm. The oral papillae are not separated.
