In this species the Dumber of mandibular laminae is large, being 

 twenty-three to twenty-six in the specimens examined. It otherwise 



differs from gigCLS, Sllbgigas and uncifer in the much greater length of 



the marginal cilia of the laminae, these equalling or exceeding t he 

 width of the stalk instead of being very much shorter; and also in the 

 obviously greater length of the distal teeth which are fewer and of 

 which the more proximal ones are less reduced in length. Cephalic 

 plate longer than wide in the ratio 1.53:1, being thus shorter than in 

 the related forms. The teeth of the prehensors are short and stout 

 and are often concave on the proximal edge but never truly uncate 

 as they are in uncifer; claws only moderately curved, the edges 

 wholly smooth. The coxopleurae lack any single specially enlarged 

 pores such as are present in subgigas. Color of head and prehensorial 

 segment chestnut, the remaining portion of body brown. 

 Pairs of legs, forty-nine.
