| H. W. Rasmussen 1950 | A Teichaster whose superomarginals are tall, slightly tumid and can be slightly wedge-shaped (longer above than below). The free abactinal lateral surface slopes envely. The median inferomarginals in the adult are very large, broad, and with a very compact appearance. The ornamentation is composed of large, uniform, closely placed spine-pits, which cover the whole surface. |
