Both arms different. Larger arm simple, egg-shaped, with eleven convex joints, one and a half times as long as broad; smaller arm in the basal half simple, triangular, with six cap-like joints, in the distal half forked; both branches egg-shaped, with five joints and blunt ends. Patagium nearly complete, with four to five concave chamber-rows.

Radius of the larger simple arm 180µm, breadth 80µm; radius of the smaller forked arm 160µm; breadth of the branches 50µm; transverse breadth of the patagium 200µm.

Etymology: Called in honour of Sir C. Wyville Thomson.
