The posterium is long, from two-fifth to nearly one-half the body length; it averages 0.04-0.06 in (1.1-1.6 mm) in length, with greatest length of 0.11 in (2.9 mm), and 0.01 in (0.3 mm) in diameter, with greatest diameter of 0.02 in (0.5 mm). The spicules of the trunk meet at a distinct angle along the dorsal midline. The long spicule blades of the posterium extend out from the body. There are two rows of prominent oral shield spicules; the oral shield is distinctively large and is divided into two lateral parts. The margin of the cloaca in lateral view is slanted. Radula and jaws large, teeth up to 0.00551 in (140 pm) long, jaws up to 0.0276 in (700 pm) long, and central plate long, up to 0.00197 in (50 pm), narrow and curved.
