Differential diagnosis
Sharpia madibai sp. nov. is mostly similar to S. soluta Faust, 1885, a species widely distributed in the Mediterranean region on Convolvulus dorycnium Linnaeus, 1759 (Friedman 2017). It can be distinguished from it by the absence of spots of white scales in the middle of interstria 2–3 (S. soluta shows such spots), and by the shape of the penis very elongate [ratio w/l: 0.15] with a series of small
erect setae on sides in S. madibai sp. nov., moderately elongate in S. soluta (ratio w/l: 0.25) and bare of setae).
Etymology
This species is dedicated to Nelson Mandela ʻMadibaʼ for the role he played in the history of the Republic of South Africa.

Description
BODY LENGTH. 2.4–3.0 mm.
COLOUR. Body integument reddish brown; vestiture consisting of imbricated scales, polygonal, shiny, completely concealing the integument, scales dark brown, pale brown and white, with white scales generally condensed along the median line of prothorax, forming a white band in the middle of 4 th interstria and near apex of interstria 1–3.
HEAD. Rostrum as long as head + prothorax and regularly downcurved in lateral view, thicker than protibiae in dorsal view, densely punctuate and striate (♂), smooth with small punctures in apical half (♀), basal ¾ (♂) or basal half (♀) of upper side bearing dense cover of pale brown scales, upper side of scrobes forming a carina slightly expanding basally near eyes; transverse furrow at base of rostrum narrow, shiny, bare of scales, with two spots of erect white scales on side near eyes; head capsule short, densely covered with scales; antennae inserted at apical ⅓ (♂) or near middle of length (♀) with segment 1 longer than 2 + 3, 4 isodiametric, segments 5–7 wider than long.
PROTHORAX. Slightly wider than long (ratio w/l: 1.02), widest in basal ⅓ of length, greatly narrowed at apex, integument concealed with rounded, almost hexagonal scales, and few scattered suberect, elongate, white scales oriented toward the centre of prothorax.
ELYTRA. Sides subparallel in basal ¾, slightly expanding toward middle of length, widest near middle (ratio w/l: 0.71), humeri raised; declivital callosities on interval 5 present but weak, followed by a depression; striae narrow, ½–¾ width of interstriae; interstriae flat, shiny, bearing two series of imbricated scales and one series of suberect elongate scales; scutellum very small.
ABDOMEN. Underside densely covered with white and grey, elliptical, overlapping scales.
LEGS. Femora clavate, unarmed; tibiae straight, unarmed, slightly bisinuate on ventral side; claws equal in length.
GENITALIA. Body of penis very elongate (ratio w/l: 0.15), 2× as long as apodemes, sides slightly convex, widest near basal ⅓, straight and converging toward apex in apical ¾, apex rounded, curvature in lateral view weak, mainly in basal half (Fig. 5A).
Life history
Host plant unknown, adults collected by sweeping vegetation. Sharpia Tournier, 1873 spp. are commonly collected on perennial non-parasitic Convolvulaceae.
Distribution
Namibia, Republic of South Africa (Kruger National Park, Northern Cape Province).
