External morphology

Small shallow depression on aboral edge. Thin lateral tufts. Size 21.7 mm x 22.3 mm.

This occlupanopsid was discovered by field researcher M. Rowell, who noticed it clutched tenaciously to a bag of potatoes in Blackstone, Virginia. Chillingly, in the span of merely a week another was collected from a bag of 5 Seed Bread in New Hampshire.  C. scobifolia shares a similar fine-fibered integument much like Octangulum fibrosum. A small divot in the rear adds to an incomplete mimicry of genus Admordorsum of the Tridentidae. Has it suddenly been sighted in your region?
