This new species has been described by Dr. Mostafa Sharaf from Wadi Abha (Saudi Arabia). Very close to Technomyrmex setosus, the main differences are 1:

"The two species are similar in size and colour, with head and gaster brown to dark brown, mesosoma yellowish brown, antennae and legs yellow. Moreover both species have a very similar complement and arrangement of setae. Comparing Technomyrmex briani with T. setosus, the eye position index (EPI) in T. briani is larger, EPI 73-117, versus EPI 75-78; this means that the eyes are located relatively posteriorly in T. briani, whereas they are located in front of the midlength in T. setosus. The metanotal groove in T. briani is deep whereas in T. setosus it is shallow, as mentioned in CollinGwood (1985). Moreover, T. briani can be separated by the few pairs of setae on the second to the fourth gastral tergites. The first gastral tergite is always bare; second and third gastral tergites mostly bare, sometimes with a single seta; the third rarely with three pairs of setae; the fourth gastral tergite always with several pairs of setae. In T. setosus the gastral tergites 1 to 4 have several pairs of setae, the longest on the first tergite about equal to the maximum diameter of the eye or fractionally shorter. Furthermore, T. briani has the posterior margin of the head with a single pair of setae in most specimens, in some specimens two or completely bare; T. setosus has two pairs of setae present on the posterior margin of the head."

The difference in pilosity is very clear in the abdomen. Check images here.
