Worker measurements (n = 10). HW 0.58–0.68, HL 0.78–0.94, LHT 0.48–0.58, CI 0.71–0.76, FCI 0.10–0.14, REL 0.28–0.31, REL2 0.39–0.44, SI 0.61–0.64, SI3 1.46–1.62, FI 0.40–0.45, PLI 0.50–0.60, PWI 0.39–0.46, LHT/ HW 0.83–0.90, CSC 0–2, MSC 0.

Worker diagnosis. Small species; masticatory margin of mandible with three teeth; minimum distance between frontal carinae slightly exceeding basal scape width (FCI 0.10–0.14, MFC/SL 0.16–0.22); scape moderately long, greater than one-half head width (SI 0.61–0.64, SI2 0.45–0.48); median lobe of clypeus produced anteriorly, usually with two pairs of lateral teeth separated by a small concavity, flanked by a weaker pair of outer lateral teeth ( Fig. 4a View FIGURES 4–6 ); profemur moderately robust (FI 0.40–0.45), legs moderately short (LHT/HL 0.61–0.65); mesopropodeal impression with irregular longitudinal rugulae, preceded by a short, raised metanotal plate ( Fig. 4b View FIGURES 4–6 ); dorsal face of propodeum subequal in length to declivitous face and rounding insensibly into the latter; petiole elongate and slender (see PLI and PWI values), with a well marked anterior peduncle and weak anteroventral tooth; postpetiole longer than broad. Integument predominantly smooth and shiny, with scattered fine punctures and weak reticulation. Standing pilosity inconspicuous, present on frontal carinae and as a single supraocular pair of setae on the vertex, absent from dorsum of mesosoma, petiole and postpetiole, sparse on succeeding abdominal segments 4–8. Dark brown, appendages lighter.

Comments. Tetraponera clypeata belongs to a cluster of closely related species—here termed the T. clypeata complex—that also includes T. dispar , T. emeryi , T. exactor , and T. furtiva . The workers of this complex can be distinguished from other African members of the allaborans group by their reduced mandibular dentition (masticatory margin with 3 teeth), closely adjacent frontal carinae (FCI 0.08-0.14), relatively long scapes (SI 0.56–0.67), and elongate petiole (PLI 0.50–0.61). T. dispar differs from T. clypeata by its smaller size (worker HW 0.51-0.52), larger eyes (worker REL 0.35), and orange-brown coloration. Workers of T. emeryi are light yellowish-orange but otherwise quite similar in structure to those of T. clypeata (see further discussion under T. emeryi ). Workers of T. furtiva are medium-brown in color, and with a shorter petiole than T. clypeata (PL/HW 0.72–0.77 in T. furtiva , versus 0.79–0.88 in T. clypeata ).

Distribution and biology. Known only from southwestern South Africa (Western Cape, Northern Cape and Eastern Cape provinces), T. clypeata nests in dead twigs, stems, and thorns of various plants. Specific nest site records include Vachellia karroo thorns, dead stem of Osteospermum , dead stem of Restionaceae , “stalks tenanted by Allodape bees”, “dead branch”, and “hollow twigs”. Recorded habitats include valley bushveld, coastal scrub forest, fynbos, fenosterbos, renosterveld, “S. Coast Strandveld”, spiny forest/thicket, and roadside.
