Bioacoustics of Warimiri karutasywa

Description. Head . In dorsal view, fastigium of vertex bilobed, blunt, wider and more prominent than antennal scape ( Figs. 7C, E ; 11C, E ); frontally, general shape reminding a heart ( Figs. 7B ; 11B ); in lateral view, slightly elevated and protruding ( Figs. 7A, D ; 11A, D ). Thorax. Meso- and metasternum transverse, trapezoid, wider than long; meso- and metabasisternal lobes reduced and acute posteroventrally; Metabasisternum transversally separated from the metasternal medial plate ( Figs. 7F , 11F ). Wings. Left stridulatory vein darker, approximately 1.24 mm long, bearing numerous microscopic teeth ( Fig. 8C ). 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. 8A–B ). Legs. All tibiae ventrally armed with two (rarely three) pairs of spurs only at the distal portion; only metafemora’s inner genicular lobe with a minute spine; all the remaining rounded ( Figs. 7A, G–H ; 11A, G–H ); internally, fore femora ventral surface armed with 2–3 mid-distal spines ( Figs. 7G ; 11G ) and mid femora with 2–3 spines only externally ( Figs. 7H ; 11H ); fore and mid tibiae dorsally smooth and flat, with slightly elevated lateral keels ( Figs. 7G–H ; 11G–H ); in lateral view, fore tibia slightly sinuous dorsally, with the surface between the concealed tympana opening a little swollen ( Figs. 7G ; 11G ); mid tibiae, in lateral view, dorsally arched ( Figs. 7H ; 11H ); hind femora ventrally with small spines on both sides and hind tibiae dorsally armed with multiple minute spines on both margins ( Figs. 7A ; 11A ). Abdomen. Male tenth tergite with posterior margin conspicuously produced behind, convex, with an almost inconspicuous medial incision ( Fig. 7I ). Male cerci short, with a short mediobasal tubercule, ending in an inward spine ( Fig. 7I ) and medio-distal portion bent downwards ( Fig. 7K ). Male subgenital plate wider than long ( Fig. 7J ). Phallic complex with two long bars comprising the sclerites TS , each ending in a conspicuous and upcurved spine, like a claw ( Figs. 9A, D–E ); process ti displaced to the dorsal fold ( df ), comprising a unique small sclerotized area. Processes mp.dl attached to the dorsalmost portion of the sclerite VS ( Figs. 9B ). Vesicles ejv ovoid ( Figs. 9B–C, E–F ), and the sclerites AP almost inconspicuous. Just like in Warimiri madiba gen. et sp. nov. , when the phallus is everted, the connection of the sclerite VS ’s ventral arms seems to be less sclerotized and tends to bend ( Fig. 9D ), and sclerites TS are strongly produced upward ( Fig. 9E ). When retracted, sclerite VS ’s dorsal arm stands obliquely, produced anteriorly, and sclerites TS arrange alongside sclerite VS (Fig. X). Female tenth tergite with posterior margin medially shallowly incised, forming two poorly defined lobes ( Fig. 9B ). Female subgenital plate expanded laterally and emarginated posteriorly, produced into two almost triangular lobes, with a widely open U-like medial sinus ( Fig. 11K ). Ovipositor small ( 6.4–7.1 mm ) and strongly upcurved ( Fig. 11I ). Measurements (mm). Males. Total size. 15; Pronotum. 6.5; Width of pronotum. 6.3; Hind femur. 12.5; Tegmina. 3. Females. Total size. 17,5–18; Pronotum. 6.5–7; Width of pronotum. 6.8–7; Hind femur. 12–13.2; Ovipositor. 6.4–7.1. Chromatic pattern. Dead and dried specimens with head and thorax reddish or reddish-brown. Lateral lobes of pronotum and lateral portion of abdomen notably darker. Dorsal portion of abdomen yellowish, flanked by sinuous lighter bands; legs also yellowish ( Figs. 7A, E ; 11A, E ). Live specimens with head and thorax reddish, with lateral lobes of pronotum reddish-brown. Abdomen laterally black and dorsally pale yellow, flanked by sinuous lighter bands. All femora basally pale pink and marked by reddish macules, tibia reddish-brown ( Figs. 10A–B ; 12A–C ).
