Worker measurements (n = 12). HW 0.58–0.69, HL 0.77–0.99, LHT 0.49–0.64, CI 0.70–0.76, FCI 0.08–0.12, REL 0.28–0.32, REL2 0.39–0.44, SI 0.64–0.68, SI3 1.54–1.69, FI 0.36–0.42, PLI 0.51–0.56, PWI 0.38–0.45, LHT/ HW 0.84–0.92, CSC 2, MSC 0.

Worker diagnosis. Similar to Tetraponera clypeata (see above) except as follows: scapes tending to be longer (SI 0.64–0.68) ( Fig. 2 View FIGURES 1–3 ), frontal carinae more closely adjacent (FCI 0.08–0.12) and profemur more slender (FI 0.36–0.42); mesopropodeal impression lacking conspicuous longitudinal rugulae; light yellowish-orange in color ( Figs 7, 8 View FIGURES 7–9 ).

Comments. Workers of T. emeryi are most readily distinguished from those of their close relative, T. clypeata , on the basis of color: light yellowish-orange as opposed to dark brown in T. clypeata . The two species are broadly sympatric in southwestern South Africa. T. emeryi workers also tend to have longer appendages and more closely adjacent frontal carinae than T. clypeata , but the relevant metrics overlap. Differences in the male terminalia, including a more dorsally deflected posteromedial margin of sternite IX (hypopygium) in T. emeryi , support their treatment as different species. For distinctions between T. emeryi and T. furtiva see under the latter species.

Distribution and biology. T. emeryi occurs from the Western Cape of South Africa east to KwaZulu-Natal and Eswatini ( Swaziland), and north as far as the Vumba Mountains in eastern Zimbabwe. Nests site records include Vachellia karroo thorns, and dead twigs of Podalyria , Buddleja , Dombeya , Vachellia caffra , “thorny vine”, and unidentified woody plants. Habitats range from from Afromontane forest and forest edge to tropical dry forest, “garden” and “riverine”.
