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, triangulär, 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 c irinse straight, 
subparallel, rather short. Antennse 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-beli- 
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 tibise 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, triangulär 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 slopin g, 
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.
