than behind, where it is evenly rounded, and without posterior angles. 

 Eyes large and convex, at the middle of the sides of the head. Ocelli 

 lacking. Mandibles long, narrow, triangular, bent downwards at their 

 tips, with straight external and finely denticulate apical borders. 

 Maxillary palpi long, 6-jointed, labial palpi 4-jointed. Clypeus short 

 and broad; clypeal apparently confluent with the antennal fovea. 

 Frontal area distinct, frontal groove obsolete Frontal ci rinse straight, 

 subparallel, rather short. Antennae long and slender; funiculi not 

 enlarged towards their tips, all the joints much longer than broad. 

 Thorax very long and narrow; seen from above somewhat dumb-bell- 

 shaped, with a long, deep mesoepinotal constriction. Both the meso- 

 and metathoracic spiracles very prominent, the latter approximated in 

 the dorsal concavity of the mesoepinotal constriction. Pro- and meso- 

 notum feebly convex, the former with a long neck, epinotum inflated, 

 egg-shaped when seen from above, in profile very convex and rounded, 

 without differentiated base and declivity. Petiole shaped somewhat 

 like that of Protaneuretus, but the peduncle very short and the anterior 

 slope of the node rising gradually, the posterior slope much more 

 abrupt. Gaster large, oval, its base not overhanging the petiole. Sting 

 long and well- developed. Legs long and slender; all the tibiae with 

 distinctly pectinated spurs; claws long and simple. 



Male. As large as the worker. Body long and slender. Head, 

 excluding the mandibles about as long as broad, with large, prominent 

 eyes and ocelli and short cheeks. Clypeus small, with feebly sinuate 

 anterior border. Mandibles similar to those of the worker, with well- 

 developed, triangular blades and long, denticulate, apical margin. 

 Palpi long, maxillary pair 6-jointed, labial pair 4-jointed. Antennae 

 long, filiform, 13 -jointed, scapes somewhat thickened, cylindrical and 

 about as long as joints 2 — 12 of the funiculus, which are subequal; 

 first funicular joint only a little longer than broad. Thorax rather 

 slender, mesonotum with pronounced Mayrian furrows; epinotum sloping, 

 rounded, without differentiated base and declivity. Petiole shaped 

 much as in the worker. Gaster apparently variable in shape, in the 

 type species long and narrow, longer than the thorax; external genitalia 

 small, retacted. Cerci not visible. Legs long. Wings rather short, with 

 a discal, two complete cubital cells and a closed marginal cell, the 

 venation closely resembling that of Iridomyrmex. Type: Paraneuretus 

 tornquisti sp. nov. 



This genus is evidently related to Aneuretus and Protaneuretus 

 but differs from these greatly in the more slender form of the body 

 and especially in the shape of the head and thorax of the worker.
