Posterior margin of head less than semi-circular behind eyes, distinctly sinuate immediately 

 behind eyes ; fontanelle slightly paler than rest of head, Y-shaped ; eyes medium sized relative 

 to head width, W/E index 30, not very prominent in proportion to own diameter, slightiv 

 angular oval ; ocelli rather small, separated from eves by slightly less than half own least 

 diameter ; postclypeus moderately inflated, width 3-0 times length, anterior margin straight, 

 posterior margin convex, rounded ; antennae 15 segmented, II slightly longer than III, III 

 than IV, and IV than V.

The distinctions between this species and N. elegant itl its have been given in the 

 discussion on the latter. N. j'ulleri also shows certain similarities to N. infuscatus, 

 but is separated in the soldier by the consistently 12 segmented antennae and in the 

 imago by the relatively shorter hind tibia. The unique morphotype female of 

 N.fulleri is damaged, and more material is needed to establish fully its relationships, 

 and distinctions from other species.
