impressed at ajx^x and elevated into an obtuse tubercle on either side of 

 inijiression. First gastric segment indistinctly impressed at middle of base. 



Mandibles shining and punctate. Head feebly shining. Clj'peus strongly 

 and foveolately punctate; front reticulately and rugosely punctate; vertex 

 with two large shallow foveae and cribriform punctures between. Pro- 

 mesothorax coarsely and reticulately costatc and subopaque. Epinotum at 

 sides more finely costate; impressed portion foveolately punctate; declivity 

 smooth and shining. Petiole finely rugose. Postpetiole and gaster more 

 shining and uniformly cribrate. Antennae and legs coarsely and densely 

 subopaque. 



Fine, squamiform hairs on head and antennal scapes, coarse ones on legs. 

 Clavate hairs on legs, outer border of scape and one in each of the two foveae 

 on vertex; fine hairs on funiculus, tarsi, and ventral surface of gaster. 



Fuscopiceous; legs, mandibles, antennae, and lamellate borders of epinotum 

 fuscorufous. Hair white. 



Ysabel: Fulakora. 



The single worker of this anomalous species was found beneath a 

 log in the forest. The curious form of the mandibles and the relatively 

 long postpetiole readily distinguish isabcUac from the other Papuasian 

 species. The lack of clavate hairs on the dorsal surface is prol)ably 

 not due to their being rubbed off, for such hairs are abundant on the 

 legs.

MoJe. Length 3 mm. 



Head, excluding eyes, much longer than broad; sides posterior to eyes 



parallel, then oblique to the occipital border which is shallowly concave. 



Vertex broadly and deeply impressed between the 



ocelli. Frontal carinae strongly elevated. Clypeus 



convex; concave anteriorly and angulate at sides. 



Mandibles small and acuminate apically. Antennae 



slender, scape broad basallj^ twice as long as first 



funicular joint; first funicular joint about a third 



as long as the second; joints two to eleven elongate 



and cylindrical, becoming shorter toward apex; 



terminal joint one and a half times as long as 



penultimate. Eyes shorter than border of clypeus, 



very convex. Mesothorax flattened posteriorly
