Holotype. Mandibles predominantly smooth with fine striations basally. Anterior clypeal margin with extensive and deep indentation. Frontal carinae absent. Eyes with 15 ommatidia in longest row. Propodeal spines long and acute (PSLI 18–20). Metapleural lobes low and rounded. Peduncle with broad keel-shaped subpetiolar process. Petiole in profile nodiform, with anterior face slightly more steeply angled with blunt corners. In dorsal view, petiolar node shaped almost rectangular broadening posteriorly with rounded corners and narrowing anteriorly with prominent blunt corners (Fig. 3D). Postpetiole low and rounded both in dorsal view and in profile. Dorsum of head with fine longitudinal striations. Spaces between striations with very fine reticulate ground sculpture. Dorsal surfaces of mesosoma and petiole with fine reticulate sculpture. Postpetiolar node predominantly smooth, with fine reticulate sculpture in places. Gastral tergite with fine reticulate sculpture. Numerous hairs on anterior clypeal margin. Dorsum of head with two pairs of erect hairs. Dorsum of mesosoma, nodes and first gastral tergite without any erect hairs, with only sparse white pubescence. Ventral surface of head with psammophore. Colour uniformly black.
MISC This species is only known from South Africa, where it has been collected in Melton Wold near Victoria West in the Northern Cape and from Oranjekrag in the Free State.
Holotype. South Africa: Northern Cape: worker, Melton Wold, 31.46741° S, 22.721550° E, 1333 m a.s.l., 7 Jan. 2009, N. Mbanyana and H.G. Robertson leg. (SAM-HYM-C023330). South African Museum Paratypes. South Africa: 2 pinned workers, same collection data as for holotype (SAM-HYM-C023329).
Named after Dr Jaco Le Roux who supervised and helped with molecular genetic work on the T. solidum group, which helped to confirm the validity of this species.
