Diagnosis
Readily distinguished from all other species of Afrepipona by submarginal carina of propodeum developed in triangular lobe above propodeal valvula. Genitalia in Fig. 27F View Fig .
Etymology
The specific epithet derives from the Latin adjective ‘lobulatus’ (= ‘with lobes’), in reference to the small lobes formed by submarginal carina.

Description
Male
MEASUREMENTS. Body length 6.2 mm; fore wing length 5.9 mm.
MORPHOLOGY. Head 1.25 × as wide as long in frontal view. Clypeus 1.3 × as wide as long, apical margin truncate with slightly projecting right-angled teeth, 0.25 × as wide as maximum width of clypeus; weakly and evenly convex in lateral view. Vertex 1.5 × as long as distance between posterior ocellus and inner eye margin; gena 0.85 × as wide as eye at bottom of ocular sinus; occipital carina complete, very fine on vertex, shortly lamellate on gena, evenly curved on gena. F1 1.25 × as long as wide and 1.25 × as long as F2, F2 subquadrate, F3–8 transverse and becoming progressively wider, F9 longer than wide, F11 finger-shaped, reaching base of F9 and barely curved in lateral view, parallel-sided with rounded apex in dorsal view. Mesosoma 1.3 × as long as wide. Sides of pronotum straight and weakly converging, humeri slightly obtuse; pronotal carina complete and lamellate, about as long as ⅓ of ocellar diameter on humeri, slightly lower medially; pretegular carina blunt, disappearing at upper margin. Mesoscutum 0.95 × as long as wide, evenly convex in lateral view. Scutellum weakly convex; anterior margin regularly crenate. Metanotum oblique and slightly projecting at anterior margin. Tegula short and not equaling parategula, outer margin evenly curved and slightly reflexed posteriorly, posterior lobe subtriangular and pointed; parategula right-angled. Epicnemial carina distinct and moderately sharp above, reaching epipleural suture. Propodeum in lateral view steeply falling just behind metanotum, almost vertical; posterior face shallowly concave and not clearly separated from dorsal faces; lateral faces flattened; lateral carinae present but very weak and confused with ridged interspaces of sculpture; submarginal carina produced in short subtriangular lobe above propodeal valvula, slightly reflexed upward. T1 semicircular, 0.5 × as long as wide; apical margin translucent, when seen in posterior view it is strongly thickened and duplicated in two lamellae. T2 0.85 × as long as wide in dorsal view, apical translucent margin about twice as long as that on T1, slightly depressed but not reflexed, preceded by series of coarse punctures. Apical margin of T3–5 similar to T2, translucent margin becoming progressively less evident. S2 strongly convex basally, then weakly and evenly convex to apex; basal longitudinal furrow very shallow, barely visible. Apical margin of S2–4 similar to respective tergites but translucent part shorter.
SCULPTURE AND VESTITURE. Clypeus coarsely and densely punctate, interspaces at most equal to diameter of punctures. Frons and vertex with deep punctures, interspaces ridge-like on frons and becoming slightly wider posteriorly; gena punctured similar to vertex but punctures becoming sparser ventrally. Scape matte and densely micropunctate. Punctures of mesosoma similar to vertex but larger and denser, interspaces mostly ridge-like; punctures slightly sparser on mesepisternum, interspaces more shiny; epicnemium and mesosternum shagreened and almost matte, with small deep punctures in posterior half; metaepisternum mostly shagreened with scattered fine punctures in lower plate, shortly striate along anterior margin; dorsal faces of propodeum with coarsely and densely punctate, interspaces reduced to sharp ridges, posterior face mostly oblique striate with deep punctures in upper half, lateral faces with sparse flat-bottomed punctures and very fine transverse microstriae. T1–2 with fine and deep punctures, circular and well-marked on T1 and disc of T2, becoming progressively more oblique toward apex and sides of T2, interspaces as long as 2–3 punctures on disc and becoming wider laterally, preapical area of T2 with series of coarse large and deep punctures preceding apical lamella; T3–5 similar to apical area of T2 but punctures much smaller and becoming progressively shallower and sparser; T6–7 shagreened with barely visible micropunctures. S1 shiny, smooth on basal petiole, irregularly ridged and deeply punctate on posterior part; S2 with deep rounded punctures, larger and denser on disc, apical lamella preceded by a series of coarse deep punctures; S3–7 shagreened and impunctate, except for series of coarse punctures preceding apical lamella on S3–4. Head and mesosoma with short silvery pubescence, mostly arising from punctures, more abundant and denser on clypeus, frons and sides of mesosoma, almost absent on epicnemium and mesosternum; clypeus with curved suberect setae; frons and mesepisternum with apically bent setae; propodeum almost entirely covered in short white pubescence, angles with dense and fine long setae; metasoma with brownish dust-like pubescence, short sub-erect setae on T3–7 and S2–7.
COLORATION. Black; following parts red: clypeus, mandible except margins,T-shaped spot on interantennal space, scape, pedicel, F1, inner eye margin, whole gena, posterior third of vertex, broad band on anterior margin of pronotum, narrow line on posterior margin of pronotum, tegula, parategula, most of dorsal faces of propodeum, most of T1, sides and preapical margin of T2, most of S1–2, legs with brownish tinges; following parts from yellow to ivory: projections of submarginal carina, narrow apical margin of T1, wide apical bands on T2–6, slightly narrower bands on S2–5, anterior face of mid and hind coxa, apex of mid tibia, line on outer face of hind tibia; apex of metasoma ferruginous. Wings subhyaline with weak brownish tinge, apex of marginal cell weakly infuscate.
