The cephalic segment of this species is small, but the basilar large, with the prebasilar fold 

 very distinct. Mandibles acute, apex black, with the tooth large and slightly tubercu- 

 lated. The labium is smooth and flattened, with the longitudinal and transverse sutures 

 distinct. The dental and subdental plates and teeth very distinct, the external tooth on 

 each side almost quadrate. The posterior segment convex, shield-shaped, with an 

 elevated obtuse longitudinal crest, commencing in a point on the front of the segment. 

 Posterior pair of legs short ; the basilar joint longer than the second, with the superior 

 surface convex ; the external margin rounded ; the internal margin and surface with 

 five acute spines tipped with black, the four anterior in two subapproximated alternating 

 series ; the fifth or apical spine acute, with the apex bifid. The internal surface flat- 

 tened, with a single spine. Inferior surface with six acute spines, arranged in three 

 longitudinal series, two in each series ; those of the external and internal parallel with 

 each other, the distal one of the latter forming part of a diagonal line with the single 

 spine on the internal surface, and the angular or posterior on the superior internal 

 margin. Lateral appendages short, convex, minutely punctured, with the apex short.
