( Figs. 37–44 )

Synagris (Paragris) biplagiatus Gusenleitner 2005: 1179 , figs. 3–4, ♀ —“ Südafrika, Western Cape, 4km S Ladismith, 33°31’57”S 21°15’11”E, 460m ” (holotype OLM).

Material examined. SOUTH AFRICA: West Cape, Cederberg , 853m, 32°28.949’S 19°14.265’E, 24–26.X.2013, leg. S. Prepsl, 1♂ ( MSVI) .

Description. Male. Body length 19 mm; fore wing length 16 mm.

Head as wide as long in frontal view. Clypeus strongly convex medially in lateral view, depressed basally; apical margin with two semicircular depressions, continued by a translucent lamella with a median semicircular incision, apical teeth of lamella pointing inward, apical incision 1.8× as broad as deep; clypeus 1.15× as wide as long ( Fig. 38 ). Distance from posterior ocellus to inner eye margin 0.37× as the distance from posterior ocellus to occipital margin; ocelli disposed as a obtuse triangle, distance between posterior ocelli 2× as long as distance between anterior ocellus and posterior ocellus; vertex inflated, with two rounded elevations behind ocelli ( Fig. 39 ). Temples 1.4× as wide as eye at bottom of ocular sinus; occipital carina entire, thickened ventrally. Ventral face of head with a tooth behind insertion of mandible ( Fig. 40 ). Scape 3.1× as long as apically wide; F1 2.4× as long as apically wide; F2–F9 longer than wide, progressively shorter; F11 short and pointed apically in lateral view, apically rounded in dorsal view, ventral margin straight, dorsal margin gently curved from base to apex, reaching middle of F8 ( Fig. 41 ). Mandibles modified, long and pointed apically; inner margin basally with a circular incision, then straight to apex, with three shallow incisions forming four very elongate teeth ( Fig. 42 ); posterior margin near articulation with a deep depression ( Fig. 40 ); inner face flat and smooth, with a small tooth near basal incision of inner margin. Mesosoma in dorsal view 1.25× as long as wide. Pronotal carina short but well-defined for entire length, forming an elevated lamella in the middle and on each humerus; a deep depression present along pretegular carina. Mesoscutum as long as wide between tegulae, convex in lateral view; a median raised line present on anterior half. Scutellum in lateral view strongly convex anteriorly, with a median longitudinal depression. Metanotum oblique, with a conical tooth on each side, depressed medially. Tegulae narrow, posterior lobe short and not equaling parategula, apically bluntly angled. Parategulae very short and curved. Mesepisternum convex, epicnemial carina strong for entire length. Propodeum broadly depressed posteriorly, with a median elongated fovea; lateral carinae strong from base to apex of propodeum, forming a short depressed tooth on lateral corners; submarginal carina developed into pointed lamellae ( Fig. 43 ). T1 2× as wide as long in dorsal view, anteriorly rounded, lateral margin weakly sinuate. T2 almost flattened in lateral view. S1 with two elevated carinae running from basal petiole to apical corners. S2 convex basally, then flattened in lateral view ( Fig. 44 ). Mid femora flattened, with a posterior median lobe.

Whole body covered by short and very dense black setae, except on pale markings of face and metasoma, where setae are yellow-orange; clypeus practically bare.

Clypeus microreticulate, with some scattered indistinct punctures, especially on basal corners. Frons with small flat bottomed punctures, interspaces equal to smaller than puncture diameters. Vertex and genae with deep medium sized punctures, interspaces larger than puncture diameters. Pronotum with very deep dense punctures, flowing into irregular striae on lateral face. Mesoscutum with punctures like pronotum, but denser anteriorly and sparse posterolaterally; micropunctate area in the middle of posterior half. Scutellum shiny with moderately dense deep punctures. Metanotum coarsely punctured between teeth, some punctures flowing together; almost impunctate in lateral parts. Mesepisternum with deep punctures, some interspaces elevated into weak striae. Metaepisternum finely and densely striate. Posterior face of propodeum transversely striate; dorsal face irregularly reticulate; lateral face strongly transversely striate except on margin with metaepisternum, where they are finely striate. Metasoma smooth, with some sparse indistinct punctures, some deeper punctures on T1 and S2.

Color. Black; following parts deep-yellow: clypeus except apical lamella, triangular marking from above antennal insertions to basal margin of clypeus, inner eye margin up to ocular sinus but not invading it, ventral face of scape, F11; following parts ferrugineous-red: antennae except F8–F10, apical segments of fore and mid tarsi; lateral spots on T2, whole T3–T7 and large lateral spots on S3–S7 orange-red. Wings fuscous with strong purplish reflections.
