| T. Kobayashi and T. Hamada 1986 | Cephalon provided with a pair of long genal spines. Glabella

Pygidium subtrigonal, a little broader than long and provided with depressed marginal border; lateral margins gently arcuate and confluent with rounded narrow posterior margin; axial lobe nearly as wide as pleural part and multisegmented ; each axial ring divided into a broad convex median part and a pair of small depressed lateral sectants ; a few anterior pleural ribs and furrows running into lateral border. |
