return to key {link to the Hymenoptera Name Server} Type location Central African Republic (holotype worker only) .

WORKER DESCRIPTION: head shape cordiform but with a near straight occiput; anterior clypeal margin very widely and shallowly arcuately impressed; palp formula 6, 4 with both sets unusually short and thick; eyes set less than 2x own length from occiput; no visible ocelli; promosenotum evenly convex in profile; propodeal dorsum long with a sharp angle to the declivity, latter flat; no setae at all on gaster segments; whole body with a quite dense covering of minute pubescence but with very little sculpturation so shiny; almost completely dark brown, including coxae, gaster segments entirely lacking decumbent hairs and with a narrow pale border.
TL ca 3.3 mm, HW 0.71, HL 0.80, CI 91, OI 26; EPI 85; SL 0.62, SI 89, PW 0.50.
Central African Republic, Dzanga-Sangha NP; Camp 1; 0303'58.3" N 1608'59.6" E 528 m; Ayous Polytrap, 15-18.x.2008; collected by Philippe Annoyer.
Name derived from the type location.

The Bolton (2007) key to Afrotropical and west Palaearctic species breaks down at couplet 7: "third gastral tergite without seta, setae present on fourth gastral tergite" as this specimen has no setae (or decumbent hairs) on any gastral segment. There is some resemblance to the Moroccan species, Technomyrmex vexatus, but that has a more heart-shaped head, with relatively smaller eyes, is a lighter brown and has setae on the fourth gastral segment. Note the photos from formicidae.org confirm my suspicion that the correct image for Bolton 2007 should be Fig 15 and not Fig 13.  A possibly better relation is Technomyrmex rusticus. The gaster in particular is very similar but not the head shape. Bolton (2007) regarded T. rusticus as being a "worker-queen intercaste" which might explain the difference.
