The body is broadly depressed, very smooth and flat dorsally. 

 Elytra are glistening pearly white and have a slight ereseentie dorsal 

 pigment pattern. Under high magnification the margin is slightly 

 fimbriated, with a few widely spaced short filaments along a short outer 

 margin. The entire upper surface is covered with clear lenticles 

 which appear as very minute granules under low magnification. The 

 body is broadly covered with the imbricating elytra except for a short, 

 2 to 4 segments, posterior end. The body terminates in a pair of long, 

 pygidial filaments. 



The prostomium has peaks directed forward. The four equally 

 small eyes are in trapezoidal arrangement, with the anterior pair located 

 in front of the middle and at the sides of the lobe; the posterior 

 eyes are near the posterior margin of the prostomium. 



Notopodial setae are all of one kind and coarser and much shorter 

 than the neuropodial setae. Each is aeicular, has a straight, blunt tip 

 and the sides are lightly spinous but appear smooth under low power; 

 they form a spreading fascicle. Neuropodial setae are longer, slenderer, 

 all about equally thick and of two kinds. The supra-aeieular setae are 

 long, spinose at the free end, and the subacicular setae are much 

 shorter, smoother and have the cutting edge oblique, adorned with a 

 row of short spinules.

All elytra have been lost. The prostomium has peaks at its an- 

 terior margin. The four eyes are large, with the anterior pair at the 

 midlength of the lobe, and the posterior eyes at the posterior margin 

 of the prostomium. Notopodial setae are much coarser than neuropodial 

 setae and transversely spinous. Neuropodials are of two kinds: the 

 superior are longer, slenderer, distally deeply bifid and spinous along 

 their free length, whereas the inferior ones are much shorter and 

 thicker, distally entire and have few or no spinules along the cutting
