Description. Colouration ( Figs 60−61 ). Head, antennomeres 1–3, apical third of antennomere 4, pronotum except lateral and posterior margins, scutellum, clavus, large elongate central spot on corium, apex of corium, membrane, legs, and ventral side of body (except ventral laterotergites), black. Lateral and posterior margin of pronotum, corium except the central spot and apex, hypocostal lamina, pronotal epipleuron, ventral and dorsal laterotergites, red. Head and pronotum shiny; scutellum, clavus, and central spot on corium dull. Antennomere 4 in basal two-thirds white.

Pilosity. Body covered with short adpressed to semierect setae, dorsum of head, callar lobe, and base of scutellum with sparse longer erect setae.

Punctation. Pronotum, scutellum, clavus, and black spots on corium with prominent, dense punctures.

Structure. Pronotum with median carina along its entire length; lateral margins nearly straight. Labium reaching between or slightly surpassing metacoxae.

Measurements (mm). Males (n = 5). Body length 11.74 (11.18–12.26); head: width (including eyes) 1.83 (1.78–1.86), interocular width 1.11 (1.03–1.19); lengths of antennomeres: 1–1.54 (1.51–1.62), 2 – 1.97 (1.75–2.11), 3 – 1.33 (1.24–1.40), 4 – 2.10 (1.89–2.32); pronotum: length 2.32 (2.16–2.48), width 3.87 (3.67–4.05); scutellum: length 1.75 (1.70–1.78), width 2.18 (2.11–2.38); corium: length 5.85 (5.51–6.05), width 2.06 (2.00–2.27).

Females (n = 5). Body length 11.79 (11.39–12.47); head: width (including eyes) 1.85 (1.78–1.89), interocular width 1.15 (1.13–1.21); lengths of antennomeres: 1 – 1.51 (1.46– 1.57), 2 – 1.85 (1.73–1.89), 3 – 1.33 (1.30–1.35), 4 – 1.99 (1.84–2.21); pronotum: length 2.20 (2.05–2.38), width 3.88 (3.73–4.10); scutellum: length 1.80 (1.62–1.94), width 2.23 (2.16–2.27); corium: length 6.24 (6.16–6.43), width 2.18 (2.11–2.32).

Differential diagnosis. Physopelta (Physopeltoides) dentipes sp. nov. is very similar to Ph. (Afrophysopelta) melanoptera Distant, 1904 externally, and it was confused with the latter species until the present study. The black central spot on the corium of Ph. dentipes sp. nov. is more elongate towards the apex of the corium (see Figs 60−61 versus 62−63) and it is also slightly larger than Ph. melanoptera (see measurements under that species). However, both species clearly differ in the characters used for defining the two subgenera (see the key above).

Etymology. The species epithet is a noun in apposition, composed of the Latin nouns dens, - tis (= tooth) and pes, - dis (= leg), referring to the characteristic denticles on legs.

Bionomics. Unknown. According to label data, the species apparently prefers higher altitudes.

Distribution. Cameroon ( DISTANT 1904, as Ph. melanoptera ), Central African Republic, Democratic Republic of the Congo (Bas-Uelé, Haut-Lomami, Ituri, Kinshasa, Kongo Central, Nord-Kivu, Sud-Kivu), Gabon, Guinea, Ivory Coast, Malawi, Nigeria, Rwanda, Sierra Leone, Uganda, Zambia, Zimbabwe (this paper).
