hairy, the distal arm long, slender, subcylindrical. Ninth pleurite 

 rather extensive, the caudal margin produced into two prominent 

 flattened processes, the more dorsal curved toward the tip, the more 

 ventral subspatulate, straight; outer pleural appendage very tiny 

 and reduced, occupying the notch between the tergite and pleurite, 

 fleshy and bearing a few long hairs at the tip; inner pleural appendage 

 elongate, slightly curved, with numerous long hairs on the outer 

 face. Ninth sternite with the dorso-caudal angle produced inward 

 as a long, flattened process which approaches the one of the opposite 

 side on the middle line beneath. The gonapophyses are powerful 

 and divaricated, of the same structure as in T. ynorrisoni. Eighth 

 sternite extensive, the caudal margin indistinctly trilobed, the 

 median area broadly convex and bearing a dense fringe of long reddish 

 hairs; on either side smaller lobes also bearing long hairs.
