Etymology. The name is an hommage of the authors to South Africa’s ex-president, Nobel Prize of Peace winner, human rights activist, and the most acknowledged Subaharian African leader, Nelson Rolihlahla Mandela (July 18, 1918 – December 5, 2013). Madiba is the name of Mandela’s clan and how he is known in many South African ethnicities. The name is a non-Latin nor Greek word is being established as a noun in apposition.

Diagnosis. The following combination of characters distinguishes Warimiri madiba gen. et sp. nov.: fastigium of vertex, in frontal view, conspicuously heart-shaped ( Figs. 2C–D View FIGURE 2 ); all tibia distinctly sinuous dorsally, bearing two pairs of spurs (rarely three pairs) only on the most distal portion of the ventral surface ( Figs. 3–B View FIGURE 3 ); only the inner genicular lobe of metafemora with a minute spine ( Fig. 3H View FIGURE 3 ); female subgenital plate narrow, with posterior lobes obtuse, shallowly incised medially with a U-like sinus ( Fig. 6G View FIGURE 6 ); male cerci short, with one apical and another subapical blunt inward tooth, and a basal and long inward spine ( Figs. 3M–N View FIGURE 3 ); phallic complex bearing sclerites TS conspicuously upcurved and with strong claw-like apices ( Figs. 5A; D–E View FIGURE 5 ); sclerite VS ’s ventral arms acute, projected laterally ( Fig. 5C View FIGURE 5 ); dorsal arm, when phallus is retracted, notably produced anteriorly (internally) ( Fig. 5B View FIGURE 5 ); process ti displaced to the fold df, comprising a unique sclerotized area ( Figs. 5A–B; E–F View FIGURE 5 ). Tenth tergite of both male and female not produced into acute lobes, but slightly sinuous posteriorly, medially shallowly incised ( Figs. 3I View FIGURE 3 ; 6F View FIGURE 6 ).

Description. Head. Fastigium of the vertex in dorsal view blunt, bilobed, wider and more prominent than antennal scape ( Figs. 2E, H View FIGURE 2 ; 6D View FIGURE 6 ); in frontal view, heart-shaped, not dentate below, and continuous with fastigium of frons ( Figs. 2C–D View FIGURE 2 ); in lateral view, slightly elevated and protruding ( Figs. 2G View FIGURE 2 ; 6C View FIGURE 6 ).

Thorax. Meso- and metasternum transverse, trapezoid, wider than long. Meso- and metabasisternal lobes reduced and acute posteroventrally ( Fig. 2F View FIGURE 2 ). Metabasisternum transversally separated from the metasternal medial plate ( Fig. 2F View FIGURE 2 ).

Wings. Left stridulatory vein darker, approximately 1.4 mm long ( Fig. 4A View FIGURE 4 ), bearing numerous microscopic teeth ( Fig. 4C View FIGURE 4 ). Radius, Medial, and Cubitus running alongside, touching till the end of the mirror, where the Cubitus bifurcates at least once, and the branches reach the apex of the tegmina, Medial reticulates, and Radius reaches the apex undivided ( Figs. 4A–B View FIGURE 4 ).

Legs. All tibiae ventrally armed with two (rarely three) pairs of spurs only at the distal portion; only inner genicular lobes of metafemora with a minute spine ( Fig. 3H View FIGURE 3 ); all remaining rounded ( Figs. 3A–B; C–D, G View FIGURE 3 ); internally, fore femora ventral surface armed with two mid-distal spines ( Figs. 3B View FIGURE 3 ) and mid femora with 2–3 spines only externally ( Fig. 3D View FIGURE 3 ); fore and mid tibiae dorsally smooth and flat, with slightly elevated lateral keels ( Figs. 3C, F View FIGURE 3 ); in lateral view, fore tibia dorsally sinuous, with the surface between the concealed tympana opening swollen ( Figs. 3A–B View FIGURE 3 ); mid tibiae, in lateral view, dorsally slightly arched ( Figs. 3D–E View FIGURE 3 ); hind femora ventrally with small spines on both sides ( Figs. 3G–H View FIGURE 3 ); hind tibiae dorsally armed with multiple minute spines on both margins ( Figs. 3G–H View FIGURE 3 ).

Abdomen. Male tenth tergite with posterior margin slightly sinuous, medially shallowly incised, forming two poorly defined lobes ( Fig. 3I–J View FIGURE 3 ); male cerci short, general shape conical, with inner surface bearing a basal inward spine, and two distal inward blunt teeth, one subapical and another apical ( Figs. 3I–N View FIGURE 3 ); male subgenital plate wider than long ( Fig. 3L View FIGURE 3 ); phallic complex with two long bars comprising the sclerites TS, each ending in a conspicuous and upcurved spine, like a claw ( Figs. 5A, D–E View FIGURE 5 ); process ti displaced to the fold df, comprising a unique sclerotized area ( Figs. 5–B, E–F View FIGURE 5 ); processes mp.dl attached to the apical most portion of sclerite VS ( Figs. 5B–C, F View FIGURE 5 ); on the ventral lobe (vl), two ovoid ejaculatory vesicles (ejv) and two almost inconspicuous sclerites of apodemes (AP) are present ( Figs. 5C, F View FIGURE 5 ). When everted, the connection of the sclerite VS ’s ventral arms seems to be less sclerotized and tends to bend, and sclerites TS are strongly produced upward ( Fig. 5D View FIGURE 5 ). When retracted, sclerite VS ’s dorsal arm stands obliquely, produced anteriorly, and sclerites TS arrange alongside sclerite VS ( Fig. 5B View FIGURE 5 ). Female tenth tergite posterior margin also bearing two small lobes; cerci small, conical, and simple ( Fig. 6F View FIGURE 6 ); female subgenital plate narrow and emarginate posteriorly, produced into two blunt lobes, with a shallow medial U-like sinus ( Fig. 6G View FIGURE 6 ); ovipositor small (6.4–7.1 mm) and strongly upcurved ( Fig. 6F View FIGURE 6 ).

Measurements (mm). Males. Total size. 14.4–18; Pronotum. 6.2–6.7; Width of pronotum. 5.1–6; Hind femur. 10.4–11.8; Tegmina. 2.7. Females. Total size. 19.3–23.7; Pronotum. 6.4–7.1; Width of pronotum. 6–6.8; Hind femur. 11.7–13; Ovipositor. 6.4–7.1.

Chromatic pattern. Body ferruginous. Dorsally, a lighter band (with even lighter lateral margins) extends from the pronotal disk anterior border to the tenth tergite posterior border ( Fig. 2B View FIGURE 2 ; 6B View FIGURE 6 ); all leg spines black or dark brown-tipped ( Fig. 3A–B, D–E, G–H View FIGURE 3 ); dorso-proximally, blackish macules present on all tibia ( Fig. 3A–H View FIGURE 3 ).
