Technomyrmex (Engramma) lujae (Forel)

Type location Zaïre (Engramma lujae, Forel, 1905b: 181, worker & male), combination in Technomyrmex by Shattuck (1992b); junior synonyms pulliceps (Santschi, 1926b: 244, worker) from Zaïre; wasmanni (Forel, 1916: 432, worker, queen & male) from Zaïre, collected by H Kohl; griseopubens (Engramma griseopubens, Wheeler, 1922: 206, illustrated, worker) from Zaïre; synonymies by Bolton (2007: worker and male only described (Bolton, 1995) .

Forel (1911f) reported Engramma lujae from Zaïre, Kasai, Kondué by Luja. Santschi (1926b) noted pulliceps differed from the type by the darker colour of the head, which is a reddish brown; the antennae are as dark as the legs; the occiput is a little less impressed.

Wheeler (1922, with the illustration) noted - "a single worker of this species was found among the numerous specimens of the preceding species (kohli) and was taken in the leaf-pouches of Scaphopetalum thonneri at Niapu. I have compared it with a cotype of lujae received from Prof. Forel and represented in the accompanying figure. Bequaert (1922, p 420), however, also reported finding it in leaf pouches of Scaphopetalum dewevrei at Kondué".

Technomyrmex (Engramma) griseopubens (Wheeler)

Type location Zaïre (Engramma griseopubens, Wheeler, 1922: 206, illustrated, worker), combination in Technomyrmex by Shattuck (1992b); worker only described (Bolton, 1995)

Wheeler (1922, with the illustration) described it as follows -
WORKER - Length 2.7 mm. Head without the mandibles slightly longer than broad, much broader behind than in front, with somewhat angularly excised posterior border and feebly convex sides. Eyes small and flat, in front of the middle of the head. Mandibles rather large, convex, their long apical margins with numerous crowded denticles. Clypeal notch semicircular, about one-fifth as broad as the anterior margin. Frontal carinae somewhat closer together than to the lateral margins of the head. Frontal area and groove obsolete. Antennae rather slender, scapes not reaching to the posterior corners of the head; first funicular joint twice as long as broad, remaining joints except the last, as broad as long. Thorax with sharply marked promesonotal and metanotal sutures, the pro- and mesonotum forming a hemispherical mass, the latter circular, the humeri rounded; the metanotal constriction moderately deep, acute; the propodeum lower than the promesonotum, only a little longer than the mesonotum, broader than long, in profile rather convex, sloping, without distinct base and declivity. Petiole of the usual shape, elliptical, with its anterior border thickened above as the vestige of the node. First gastric segment overlying the petiole as in the other species of the genus; anus nearly terminal. Legs rather slender.
Shining; whole body very finely and uniformly punctate. Hairs absent, except on the mandibles and tip of the gaster, where they are very short. Pubescence gray, short and fine, rather abundant, uniformly covering the whole body, but not concealing the surface. Black; mandibles, sides of clypeus, cheeks and gula brown.

Described from a single specimen taken by Lang and Chapin on firewood between Lukolela and Basoko. This species is quite distinct in the shape of the thorax, in sculpture, and in pilosity.
