Technomyrmex (Engramma) gowdeyi (Wheeler)

Type location Uganda (not Zaïre; Engramma gowdeyi, Wheeler, 1922: 53, worker, illustrated), combination in Technomyrmex by Shattuck (1992b); all forms described (Bolton, 1995, where type location was wrong).

Wheeler (1922, with the illustration) wrote - The following species, though not from the Congo, may be most conveniently described in this place.

WORKER - Length 2.4 to 2.7 mm. Head without the mandibles distinctly longer than broad, broader behind than in front, with feebly concave posterior border and feebly convex sides. Eyes flat, in front of the middle of the head, about one-fifth as long as its sides. Mandibles convex, with about a dozen even, crowded teeth. Clypeal notch about one-fourth the length of the anterior border, broader than deep, with sharp, slightly produced corners. Posterior clypeal border distinct; frontal area and groove obsolete; frontal carinae nearer to the sides of the head than to each other. Antennal scapes extending about one-sixth their length beyond the occipital border; funicular joints 2 to 10 perceptibly longer than broad. Thorax short, seen from above with distinctly angular humeri; promesonotal and metanotal sutures distinct; pro- and mesonotum moderately convex, the latter broadly elliptical, slightly broader than long; metanotal constriction rather deep, acute. Propodeum as long as broad, broader behind than in front, in profile with a short base, rising rather steeply from the metanotal groove, one-fourth as long as the flat, backwardly sloping declivity. Petiole elliptical, flat, its node obsolete. Gaster rather voluminous, its first segment overlying the petiole; anus terminal. Legs rather slender. Shining; very finely and uniformly punctate.
Hairs sparse, blackish, erect, rather coarse, present on the clypeus, vertex, pronotum, mesonotum, and propodeum, and all the segments of the gaster. Pubescence grayish, short and fine, rather abundant, covering the whole body but not concealing the shining surface. Castaneous brown; thorax and anterior portion, of head paler; mandibles, insertions of antennae, funiculi, tarsi, and articulations of legs yellowish brown.

Described from numerous specimens taken by Mr. C. C. Gowdey at Kampala, Uganda. I at, first supposed this form to be E. ilgi subspecies stygium Santschi, described from British East Africa, but careful perusal of the description shows that it is quite distinct.
