Etymology. The name derives from the combination of two words of the Nheengatu language: karú = eat + tas’y(wa) = ant. This name refers to the fact that ant remains were found in the digestive tract of dissected specimens. The name is a non-Latin nor Greek word and must be treated as an arbitrary combination of letters.

Diagnosis. Like in Warimiri madiba   gen. et sp. nov., this species has the fastigium of vertex heart-shaped in frontal view ( Figs. 7B View FIGURE 7 ; 11B View FIGURE 11 ); all tibia distinctly sinuous dorsally, bearing two pairs of spurs on the ventral surface most distal portion ( Figs. 7A, G–H View FIGURE 7 ; 11A, G–H View FIGURE 11 ), minute spine only the inner genicular lobe of metafemora ( Figs. 7A, G–H View FIGURE 7 ; 11A, G–H View FIGURE 11 ), and the tenth tergite of female slightly sinuous posteriorly, medially shallowly incised, produced into two broad lobes ( Fig. 11J View FIGURE 11 ). However, Warimiri karutasywa   gen. et sp. nov. differs from the species abovementioned by the female subgenital plate more expanded laterally, with a wider medial sinus ( Fig. 11K View FIGURE 11 ), male cerci ending in an inward spine, and with a short mediobasal tubercule ( Fig. 7I View FIGURE 7 ), and male tenth tergite distinctly produced posteriorly, convex, with just an almost inconspicuous medial incision ( Fig. 7I View FIGURE 7 ).

Description. Head. In dorsal view, fastigium of vertex bilobed, blunt, wider and more prominent than antennal scape ( Figs. 7C, E View FIGURE 7 ; 11C, E View FIGURE 11 ); frontally, general shape reminding a heart ( Figs. 7B View FIGURE 7 ; 11B View FIGURE 11 ); in lateral view, slightly elevated and protruding ( Figs. 7A, D View FIGURE 7 ; 11A, D View FIGURE 11 ).

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 View FIGURE 7 , 11F View FIGURE 11 ).

Wings. Left stridulatory vein darker, approximately 1.24 mm long, bearing numerous microscopic teeth ( Fig. 8C View FIGURE 8 ). 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 View FIGURE 8 ).

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 View FIGURE 7 ; 11A, G–H View FIGURE 11 ); internally, fore femora ventral surface armed with 2–3 mid-distal spines ( Figs. 7G View FIGURE 7 ; 11G View FIGURE 11 ) and mid femora with 2–3 spines only externally ( Figs. 7H View FIGURE 7 ; 11H View FIGURE 11 ); fore and mid tibiae dorsally smooth and flat, with slightly elevated lateral keels ( Figs. 7G–H View FIGURE 7 ; 11G–H View FIGURE 11 ); in lateral view, fore tibia slightly sinuous dorsally, with the surface between the concealed tympana opening a little swollen ( Figs. 7G View FIGURE 7 ; 11G View FIGURE 11 ); mid tibiae, in lateral view, dorsally arched ( Figs. 7H View FIGURE 7 ; 11H View FIGURE 11 ); hind femora ventrally with small spines on both sides and hind tibiae dorsally armed with multiple minute spines on both margins ( Figs. 7A View FIGURE 7 ; 11A View FIGURE 11 ).

Abdomen. Male tenth tergite with posterior margin conspicuously produced behind, convex, with an almost inconspicuous medial incision ( Fig. 7I View FIGURE 7 ). Male cerci short, with a short mediobasal tubercule, ending in an inward spine ( Fig. 7I View FIGURE 7 ) and medio-distal portion bent downwards ( Fig. 7K View FIGURE 7 ). Male subgenital plate wider than long ( Fig. 7J View FIGURE 7 ). 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 View FIGURE 9 ); 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 View FIGURE 9 ). Vesicles ejv ovoid ( Figs. 9B–C, E–F View FIGURE 9 ), 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 View FIGURE 9 ), and sclerites TS are strongly produced upward ( Fig. 9E View FIGURE 9 ). 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 View FIGURE 9 ). Female subgenital plate expanded laterally and emarginated posteriorly, produced into two almost triangular lobes, with a widely open U-like medial sinus ( Fig. 11K View FIGURE 11 ). Ovipositor small (6.4–7.1 mm) and strongly upcurved ( Fig. 11I View FIGURE 11 ).

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 View FIGURE 7 ; 11A, E View FIGURE 11 ). 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 View FIGURE 10 ; 12A–C View FIGURE 12 ).

Comments. Warimiri karutasywa   gen. et sp. nov. specimens were found overnight on the ground, mainly on the margins of open areas such as trails or roads ( Fig. 13 View FIGURE 13 ). Unlike other species of Warimiri   gen. nov. described herein, male specimens of Warimiri karutasywa   gen. et sp. nov. were scarce compared to females, and only one specimen was collected. During the dissection of some specimens, cephalic capsules of ants were found inside the crop. Probably these katydids feed on ants since these social insects are abundant on the soil.
