Bioacoustics of Warimiri madiba

Description. Head . Fastigium of the vertex in dorsal view blunt, bilobed, wider and more prominent than antennal scape ( Figs. 2E, H ; 6D ); in frontal view, heart-shaped, not dentate below, and continuous with fastigium of frons ( Figs. 2C–D ); in lateral view, slightly elevated and protruding ( Figs. 2G ; 6C ). Thorax. Meso- and metasternum transverse, trapezoid, wider than long. Meso- and metabasisternal lobes reduced and acute posteroventrally ( Fig. 2F ). Metabasisternum transversally separated from the metasternal medial plate ( Fig. 2F ). Wings. Left stridulatory vein darker, approximately 1.4 mm long ( Fig. 4A ), bearing numerous microscopic teeth ( Fig. 4C ). 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 ). 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 ); all remaining rounded ( Figs. 3A–B; C–D, G ); internally, fore femora ventral surface armed with two mid-distal spines ( Figs. 3B ) and mid femora with 2–3 spines only externally ( Fig. 3D ); fore and mid tibiae dorsally smooth and flat, with slightly elevated lateral keels ( Figs. 3C, F ); in lateral view, fore tibia dorsally sinuous, with the surface between the concealed tympana opening swollen ( Figs. 3A–B ); mid tibiae, in lateral view, dorsally slightly arched ( Figs. 3D–E ); hind femora ventrally with small spines on both sides ( Figs. 3G–H ); hind tibiae dorsally armed with multiple minute spines on both margins ( Figs. 3G–H ). Abdomen. Male tenth tergite with posterior margin slightly sinuous, medially shallowly incised, forming two poorly defined lobes ( Fig. 3I–J ); 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 ); male subgenital plate wider than long ( Fig. 3L ); 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 ); process ti displaced to the fold df , comprising a unique sclerotized area ( Figs. 5–B, E–F ); processes mp.dl attached to the apical most portion of sclerite VS ( Figs. 5B–C, F ); on the ventral lobe ( vl ), two ovoid ejaculatory vesicles ( ejv ) and two almost inconspicuous sclerites of apodemes ( AP ) are present ( Figs. 5C, F ). 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 ). When retracted, sclerite VS ’s dorsal arm stands obliquely, produced anteriorly, and sclerites TS arrange alongside sclerite VS ( Fig. 5B ). Female tenth tergite posterior margin also bearing two small lobes; cerci small, conical, and simple ( Fig. 6F ); female subgenital plate narrow and emarginate posteriorly, produced into two blunt lobes, with a shallow medial U-like sinus ( Fig. 6G ); ovipositor small ( 6.4–7.1 mm ) and strongly upcurved ( Fig. 6F ). 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 ; 6B ); all leg spines black or dark brown-tipped ( Fig. 3A–B, D–E, G–H ); dorso-proximally, blackish macules present on all tibia ( Fig. 3A–H ).
