occipital corners by one sixth of their length; first funicular joint the longest, 

 second and third subequal, terminal not as long as the two preceding joints 

 together. Eyes very small and little convex, their distance from base of 

 mandibles more than twice their longitudinal diameter. Pronotum a little 

 broader than long. Mesoepinotum without suture, nearly flat above. Petiole 

 from above subconical, broadest behind, narrowed in front, with rounded 

 posterior corners; in profile longer than high, the dorsal surface nearly three 

 times as long as the anterior, and rounding in front and behind into the ante- 

 rior and posterior surfaces which are flat. 



Very shining. Mandibles with coarse punctures. Clypeus irregularly 

 striate. Front of head outward from antennal fossae rugulose, the remainder 

 of head with coarse punctures and the body with regular, widely separated 

 strong, punctures, though not as coarse as those of head. 



Dark reddish brown, legs and tip of gaster lighter, antennae yellowish brown. 



VitiLevu: Nadarivatu. 



Described from two workers. This is a very small species, quite 

 distinct in the shape of the head and in the very small size of the eyes. 

 The mesoepinotum is proportionately broader than in the related 

 Fijian species.

Worker. Length 5-5.5 mm. 



Head distinctly longer than broad, a little broader in front than behind, with 

 slightly convex sides, rounded corners and straight occipital border. Apical

borders of mandibles concave, separated from basal borders by a rounded 

 angle, edentate. Antennal scapes surpassing the occipital borders by about 

 one third their length; first, second, and third funictilar joints more than twice 

 as long as broad, the remaining joints shorter and thicker, terminal joint dis- 

 tinctly shorter than the two preceding joints. Eyes rather large, their 

 distance from base of mandibles about equal to their longitudinal diameter.
