Description

Worker. Ferruginous, shining; mandibular teeth, anterior border of head, femora, tibiae and the two posterior thirds of the gaster, sometimes also the upper surface of the head with the scapes, more or less brown. Mandibles nearly smooth and shining, with a few, very scattered punctures; their terminal border armed with three teeth anteriorly and indistinctly denticulate behind. Head (without the mandibles) nearly as long as broad, slightly narrowed in front, strongly rounded at the posterior angles. Cheeks in front of the eyes, together with the spaces between the eyes and the frontal carinae, longitudinally rugose, the rugae becoming semicircular around the articulations of the antennae; the remainder of the head, with the clypeus and frontal area, smooth and very shining. Antennae 12-jointed; funicular joints 2-7 transverse. Thorax with coarse rugae, transverse above, lonitudinal on the sides; the sculpture rather effaced on the disc of the pronotum and the declivity of the propodeum. Pronotum convex, unarmed above, its interior border much raised above the articulation of the anterior coxae and terminating in front in a blunt denticle. There is a deep constriction between the mesonotum and propodeum; the latter, very narrow above, terminates at the juncture of the basal and declivous surfaces in two strong, acute teeth, which are very divergent and directed upward. Petiole surmonthed by an acute cone, inclined forward; postpetiole transverse, armed with a small dentiform tubercle at its anterior angles; the petiole is transversely rugose above, the postpetiole nearly smooth, except behind, where there are a few more or less effaced rugae. Gaster smooth and very shining. Coxae very globular; femora only slightly swollen; four posterior tibiae without spurs. Whole body, including the antennal scapes and legs bristling with long, yellowish, delicate and moderately abundant hairs. Length 4.5-5 mm.
