indicated a shallow furrow running along the middle of the ventral surface, dividing each half into a larger anterior triangle and a smaller posterior triangle. Although he did not indicate this specifically, he was probably referring to the anterolateral and posterior portions of the shield. He also counted 40 tufts of chaetae along the margins of the shield. If the secondary groups of chaetae, such as the delicate fascicles at the posterolateral edges are included, there are still only 34. Because one syntype is very large, and chaetal fascicles may be irregularly broken, he might have inadvertently counted a few of the fascicles more than once.
