Queen
(dealated). Length nearly 6.5 mm.

Head almost square, very slightly longer than broad and slightly broader behind than in front, with acutely pointed posterior corners and broadly excised posterior border. Mandibles large and convex, with three large apical and a few indistinct basal teeth. Clypeus rather flat, with a median carina and an abbreviated costa on each side, the anterior border distinctly notched in the middle and sinuate on each side. Frontal area triangular, longer than broad; frontal carinae rapidly diverging behind, extending nearly to the posterior fourth of the head, forming the inner borders of distinct but not very deep scrobes for the antennal scapes. Eyes moderately large and convex, in front of the median transverse diameter of the head. Antennae short, scapes slightly curved! reaching nearly to the posterior third of the head; funicular joints 2-7 broader than long, joint 8 as long as broad, 9-11 longer than and forming a rather distinct club. Thorax evenly convex above, narrower than the head, broader in front than behind, humeral angles obtuse. Epinotum rounded and convex, without distinct base and declivity, the metasterna prominent, rounded. Petiole cylindrical, from above oblong, nearly two and one-half times as long as broad, with parallel sides, in profile slightly arcuate, without a node, its ventral border at the anterior end with a well-developed, anteriorly directed tooth. Post petiole broader than the petiole, longer than broad, broader and higher behind than in front, with a small, acute anteroventral tooth. Gaster broadly and regularly elliptical, not larger than the head, formed very largely by the first segment, Femora strongly and abruptly incrassate beyond their basal third, which is slender. Tibiae only slightly thickened, tarsi slender.

Shining; mandibles strongly striate; surface of clypeus uneven, indistinctly longitudinally rugose on the sides. Head coarsely and rather loosely rugose, the rugae on the upper surface longitudinal, diverging behind, on the sides and behind more reticulate, the interrugal spaces rather smooth on the front, vaguely and finely punctate. Sculpture of thorax and petiole similar to that of the head, the rugae on the mesonotum and scutellum longitudinal, on the pronotum, pleurae, petiole and postpetiole reticulate, on the postpetiole feebler than on the thorax. Gaster subopaque, finely and densely reticulate, the base of the first segment sharply longitudinally rugulose or striate. Coxae finely reticulate, remainder of legs shining.

Body and appendages covered with moderately abundant, stiff, rather obtuse, yellow hairs.

Ferruginous, gaster paler and more yellowish; antennal funiculi, mandibular teeth and wing insertions black; legs yellowish, except the tarsi, the knees of the fore pair and the knees and tibiae of the middle and hind pairs, which are ferruginous.

Type Material
A single specimen from Sebesi. (Dammerman).
