Dorsal labiate plate with one small sclerite laterocaudad to sclerotized rings; posterior wall with subquadrate interramal lobes ( Fig. 20 , irl); dorsal structure small and medial process absent ( Fig. 20 , ds).

Diferential diagnosis. Nabidomiris natalensis sp. nov. can be distinguished by the pronotum without spots on the humeral region; basal margin of pronotum at least 1.67 times the width of head; endosoma with medial sclerite fusiform, ventral right sclerite ovoid and short longitudinal spicule on ventral area.

This new species is more similar to N. clypealis with regard to the general aspect of the body, the male genitalia, and the presence of a tubercle on the ventral left margin of the aperture of the pygophore. Nabidomiris natalensis sp. nov. can be distinguished from N. clypealis because in addition to the tubercle on the ventral margin of the pygophore, it also has a medium-sized tubercle on the left dorsal margin of the genital aperture which is not present in N. clypealis .

The endosoma of the males of the species of Nabidomiris has four endosomal sclerites: a ribbon-like sclerite (rs), medial sclerite (ms), ventral right sclerite (vrs), and a sclerite on its ventral surface (sgs); N. natalensis sp. nov. has an additional short longitudinal spicule ( Fig. 13 , s), apparently unique among the species of Nabidomiris .

The coloration of the body is similar in the three previously described species of Nabidomiris ( Figs 1–3 ), in which the pronotum has paired dark spots on the humeral angles and the hemelytra has large brown spots ( LINNAVUORI 1975, ODHIAMBO 1958). Nabidomiris natalensis sp. nov., however, differs by having the pronotum uniformly colored, without dark spots on the humeral angles, and by having the head with a median longitudinal red line, and coloration which differs strikingly from that of the other species.

Etymology. The species name natalensis (- is, - e) is an adjective referring to the Natal region in South Africa, nowadays KwaZulu-Natal, where most of the specimens were collected.

Plant associations. Unknown.

Distribution. This new species is known only from South Africa (KwaZulu-Natal and Transvaal) ( Fig. 21 ).
