Anthidium bruneipes Friese, 1913b: 578 (holotype—‘1♀von Kl. Namaland, im Oktober. Kapland’ (ZMHB, examined) South Africa).
Dianthidium (Spinanthidium) bruneipes: Mavromoustakis 1951: 977.

Diagnosis. Female Plesianthidium bruneipes can be distinguished from all other Plesianthidium by the largely orange mandible alone (Fig. 24 b). Additionally, the combination of orange apical margins on the metasomal terga (Fig. 24 a), largely orange legs, apical tergal fasciae (Fig. 24 a) and distinct shoulder on T6 (Fig. 24 e) are diagnostic. In males the combination of apical margins of terga orange (Fig. 24 c), legs largely orange (Fig. 24 c) and clypeus yellow (Fig. 24 d) are diagnostic. The structures of the male T7 (Figs 25 a, b) and S6–S8 (Figs 25 c–e) are also diagnostic.
Description. Female. Lengths: face 3.4–3.9 mm; scutum 3.0– 3.3 mm; forewing 9.0– 10.5 mm; body 9.5–12.1 mm. Integument black, except mandible, tegula and legs orange, distal margins of T1–T5 translucent orange (Figs 24 a, b). Pubescence mostly white, except vertex, scutum orange (Fig. 24 a) and scopa orange. T2–T5 with weakly developed distal fasciae (Fig. 24 a, most visible in lateral view). Preoccipital ridge rounded; distance between lateral ocellus and preoccipital ridge 2.5x ocellar diameter; supraclypeus distinctly convex; clypeus distinctly convex, sparsely punctate, not modified ventrally, ventral edge straight; mandible with three teeth; maxillary palpus 2-segmented; scutum very densely punctate; tegula densely punctate medially; propodeum glabrous medioventrally; T6 distinctly expanded anterolaterally; S6 without mediolongitudinal carina.
Male. Lengths: face 3.4–4.9 mm; scutum 3.0– 3.4 mm; forewing 9.7–10.1 mm; body 10.9–12.0 mm. Integument black, except tegula entirely and legs largely orange, distal margins of T1–T5 translucent orange, clypeus yellow (Fig. 24 d). Pubescence mostly white, except vertex and scutum orange (Fig. 24 c); T2–T5 with weakly developed distal fasciae (Fig. 24 c, most visible in lateral view). Preoccipital ridge rounded; distance between lateral ocellus and preoccipital ridge twice ocellar diameter; supraclypeus distinctly convex; clypeus distinctly convex, densely punctate; mandible with three distinct teeth; maxillary palpus 2-segmented; scutum very densely punctate medially; tegula densely punctate; propodeum glabrous medioventrally; hind trochanter without ventral spine; T6 with distinct mediolongitudinal carina, with distinct tubercle posteromedially, with distinct lateral spine apically, distal margin punctate, without distal flange; T7 posterior edge tridentate, with large lateral and median teeth, all spines narrow, median truncate, lateral pointed (Figs 25 a, b); S4 without apicomedian comb; S5 posterior edge not distinctly concave, with pointed triangular projection posteromedially; S6 with posterior edge forming obtuse-angle (Fig. 25 c); S7 disc short, broadly and deeply concave posteriorly (Fig. 25 d); S8 with disc long, strongly concave posterolaterally, truncate posteromedially, sides straight (Fig. 25 e); gonostylus concave apicolaterally (Fig. 25 f).
Distribution (Fig. 26). This species is only known from Namaqualand, South Africa.
