10. Wheeleripone lucida, sp. nov. 



Worker. Length 3 mm. 



Differing from the preceding species in the much smaller size and in the form 

 of the petiole, which in profile is distinctly higher than long, convexly declivous 

 in front, with the flat anterior space very poorly defined. 



There are no striae on the mesonotum, which is very smooth and shining. 

 Otherwise it is a miniature of albidava in form, sculpture, and color, but with 

 more abundant and proportionately coarser hairs on the head and body.
