Diagnosis. Plesianthidium neli can be distinguished from all Plesianthidium , except P. namaquaense by the combination of terga with orange distal bands and legs black ( Figs 27 View FIGURE 27 a, c). Females differ from P. namaquaense in the typically smaller size, clypeus impunctate medially ( Fig. 27 View FIGURE 27 b), scutum densely but not contiguously punctate and T5 with very narrow impunctate margin (approximately 1 puncture width). Males differ from P. namaquaense in the smaller body size, clypeus weakly impunctate medially, distance between lateral ocellus and preoccipital ridge shorter (1.5x ocellar diameters) and T5 with very narrow impunctate margin (approximately 1 puncture width). The structure of male T7 ( Figs 28 View FIGURE 28 a, b) and S6–S8 ( Fig. 28 View FIGURE 28 c–e) are somewhat diagnostic but not between P. neli and P. namaquaense .

Plesianthidium neli , P. namaquaense and P. ca l v i ni are very similar. They differ mostly in the colour of their legs and their relative size. Plesianthidium neli is smaller than P. namaquaense and has black legs. Small differences occur between the male terminalia of P. ne l i and P. calvini , but not between P. neli and P. namaquaense .

Description. Female. Lengths: face 2.7–3.1 mm; scutum 2.2–2.5 mm; forewing 6.3–7.2 mm; body 8.1–10.2 mm. Integument black, except tegula and distal margins of T1–T5 translucent orange ( Fig. 27 View FIGURE 27 a). Pubescence white (including scopa), except for vertex and scutum orangish ( Figs 27 View FIGURE 27 a, b); scopa whitish; metasomal terga without distal fasciae. Preoccipital ridge rounded; distance between lateral ocellus and preoccipital ridge 1.5x ocellar diameter; supraclypeus convex; clypeus gently convex, ventral region not modified, ventral edge crenulate, sparsely punctate, shiny between punctures; mandible with two distinct teeth and three small teeth; maxillary palpus 2-segmented; scutum densely but not contiguously punctate, shiny between punctures; tegula sparsely punctate medially; propodeum glabrous medioventrally; T2–T3 punctate distally; T6 not expanded laterally, without mediolongitudinal carina.

Male. Lengths: face 2.3–3.0 mm; scutum 1.9–2.6 mm; forewing 6.6–8.0 mm; body 7.4–9.5 mm. Integument black, except tegula and distal margins of T1–T5 translucent orange ( Fig. 27 View FIGURE 27 c). Pubescence white, except for vertex and scutum orangish ( Figs 27 View FIGURE 27 c, d); metasomal terga without distal fasciae. Preoccipital ridge rounded; distance between lateral ocellus and preoccipital ridge 1.5x ocellar diameter; supraclypeus distinctly convex; clypeus distinctly convex, densely punctate, but a little less dense medioventrally; mandible with three distinct teeth; maxillary palpus 2-segmented; scutum densely punctate medially, dull between punctures; tegula densely punctate; propodeum mostly punctate, impunctate medioventrally; hind trochanter without ventral spine; T6 without mediolongitudinal carina, with large posteromedially tubercle, with distinct lateral spines, without impunctate distal margin, without distal flange ( Fig. 28 View FIGURE 28 a); T7 posterior edge tridentate moderately large lateral and median teeth, all spines narrow, median truncate, lateral pointed ( Figs 28 View FIGURE 28 a, b); S4 without apicomedian comb; S5 posterior edge shallowly concave; S6 broadly convex ( Fig. 28 View FIGURE 28 c); S7 disc short, with broad, rounded posterior concavity ( Fig. 28 View FIGURE 28 d); S8 with disc long, strongly concave posterolaterally, truncate posteromedially, sides straight ( Fig. 28 View FIGURE 28 e); gonostylus concave apicolaterally ( Fig. 28 View FIGURE 28 f).

Distribution ( Fig. 29 View FIGURE 29 ). This species is mostly known from Namaqualand. It also occurs in the fynbos and the cold bokkeveld, all in South Africa.
