WorkKER. Length 2.5-5.5 mm. 
Head even in the largest workers longer than broad, distinctly 
narrower in front than behind, with very feebly convex cheeks and 
posterior border and broadly rounded posterior angles. Eyes rather 
small, but convex, their long axes decidedly shorter than the distance 
between their anterior border and the anterior corners of the head. 
Clypeus sharply carinate, its anterior border angularly produced in 
the middle. Antennae rather slender, scapes but slightly enlarged 
towards their tips; first funicular joint as long as the two succeeding 
joints together; these two joints subequal and each slightly shorter 
than the penultimate joints. Maxillary palpi moderately long. 
Frontal carinae not abbreviated, scarcely diverging behind. Thorax 
slender, pro- and mesonotum moderately convex, mesoépinotal constric- 
tion moderately deep, epinotum with subequal base and declivity, 
usually rounded, without distinct base and declivity but in some 
specimens more angular. Petiole narrow, with convex anterior and 
flat posterior surface and rather blunt border, which is entire and 
rounded when seen from behind. Gaster small; legs slender. 
Surface of body smooth and shining, very finely and superficially 
shagreened. Mandibles and clypeus very finely and densely, longi- 
tudinally striated. In the largest workers the anterior half of the 
head and the thorax may be subopaque. Frontal area smooth and 
usually shining. 
Hairs white, delicate, erect, rather blunt, abundant and moderately 
long, present on the upper surface of the head, the gula, whole upper 
surface of thorax, petiole, and gaster. Pubescence white, very sparse 
but long and distinct on the gaster and legs, and often also on the head 
and thorax; very fine and dense on the antennal scapes. 
Black or very dark brown, the thorax and petiole often more or less 
piceous or reddish brown, with paler sutures; the head and gaster 
usually with bronzy reflections; mandibles, antennae, legs, and some- 
times also the cheeks and clypeus red; femora sometimes infuscated 
in the middle.
