Specimen Labels

Although this species was described from Surinam as long ago as 1863 it is infrequently mentioned in the literature, probably because it has been taken only occasionally in sweepings. Two colonies which I found in British Guiana were nesting in dead branches. One of them contained a number of specimens of the hitherto unknown female. (Wheeler 1934)

Identification

Distribution

Wheeler (1934) noted "collected a number of workers and females from Kalocoon, Kartabo and Bartica, British Guiana. I have recorded the species also from Port of Spain, Trinidad (R. Thaxter) and have received specimens from San Antonio del Rio Cotuhe and La Chorrera, Putumayo Distr., Peru (J. C. Bradley). Goeldi took it at Para, in Northern Brazil, Jelski in Cayenne, and Emery records it from Bolivia. It seems, therefore, to have a rather circumscribed range and to be confined to South America.

Description

Queen

Wheeler (1934) - Length 8-9 mm.

Head trapezoidal, as broad as long, narrowed anteriorly, with straight sides and posterior border and nearly rectangular posterior corners. Antennal scapes extending somewhat more than their greatest diameter beyond the posterior corners of the head. Thorax slightly broader than the head, with pro- and mesonotum of the usual shape in female Camponoti; epinotum with sharply differentiated base and declivity, the former nearly twice as broad as long, broader anteriorly than posteriorly, strongly convex, with a shallow median groove, its posterior border distinctly emarginate in the middle and rather sharp, forming an acute angle with the concave and rather steep declivity, much as in the worker. Petiole not truncated above as in the worker, but cuneate as inmost Camponoti, with only anterior and posterior surfaces, the former convex and perpendicular, the latter flat and sloping, the superior border broadly rounded, acute and entire, or occasionally emarginate in the middle. Gaster elongate elliptical. Wings rather short, measuring slightly more than 7 mm.

Sculpture, pilosity and color as in the worker, but the vertex with a large, brown, butterfly-shaped spot and each gastric segment posteriorly with a broad brown fascia sharply marked off from the yellow border of the segment but anteriorly shading into the yellowish ferruginous basal portion. Knees, tibiae and tarsi of middle and hind legs darker brown than in the worker. Wings yellow, with deep resin yellow veins and pterostigma.
