Described from a single soldier and four workers from Sarawak, 

 (Roland Thaxter). Type— M. C. Z. 8,947. 



This species is evidently related to Ph. nodgii Forel of Java, but 

 the soldier is smaller, with more deeply notched clypeiis, much less 

 distinct antennal scrobes, shorter epinotal spines, more deeply notched 

 petiolar node, laterally less angular postpetiole, and very different 

 thoracic sculpture. The worker bugi is also smaller than that of 

 nodgii, has a more elongate head, very feebly armed epinotum, a 

 more rounded postpetiole, and very different sculpture.
