Bioacoustics of Warimiri zumbi

Description. Head. Fastigium of the vertex in dorsal view blunt, wider and more prominent than antennal scape ( Figs. 14E, H ; 19D ). In frontal view, like an inverted triangle but not heart-shaped ( Fig. 14C, D ); in lateral view, slightly elevated and protruding ( Figs. 14G ; 19C ). Thorax. Meso- and metasternum transverse, trapezoid, wider than long, but longer than the other congeneric species; meso- and metabasisternal lobes reduced and acute ventro-posteriorly. Metabsisternum transversally separated from the metasternal medial plate ( Fig. 14F ). Wings. Radius, Medial, and Cubitus running alongside, touching, till the end of the mirror, where the Cubitus reticulates, and Radius and Medial continue till the distal border parallelly ( Figs. 16A–B ). Left stridulatory file 1.08 mm long, bearing numerous microscopic teeth ( Fig. 16C ). Legs . Fore femora ventrally armed with 1–3 spines on inner margin ( Fig. 15B ), and on the outer margin, when present, there is only one minute spine ( Fig. 15A ); ventral surface of mid femora armed externally with 2–3 spines ( Fig. 15D ) and internally usually smooth or, at most, with one tiny spine ( Fig. 15E ). Inner genicular lobe of mid femora and both genicular lobes of hind femora with a spine ( Figs. 15E, G–H ). Fore and mid tibia with four pairs of spurs medio-distally, dorsal surface smooth ( Figs. 15A–F ). In lateral view, fore tibia straight, except by the tympanal area ( Figs. 15A–B ), and mid tibia with dorsal surface slightly arched ( Figs. 15D–E ). Hind tibia with 3–4 pairs of spurs only distally and, in dorsal view, sinuous. Hind tibia armed dorsally with multiple spines on both margins ( Figs. 15G–H ). Abdomen. Male and female tenth tergite very similar to Warimiri madiba gen. et sp. nov. , with a posterior margin produced into two lobes ( Figs. 15I ; 19F ). Male cerci without basal appendage, only with a medio-distal inward finger-like projection, followed by a conspicuous inward subapical spine ( Figs. 15I–J ). Male subgenital plate broad, wider than long, somehow cupuliform ( Figs. 15J–L ). Female subgenital plate small and narrow, emarginated into two acute projections posteriorly ( Fig. 19G ). The ovipositor is the longest of the genera ( 9.2–9.3 mm ), strongly upcurved ( Fig. 16F ). Phallic complex bearing sclerites TS not so long as in the other congeneric species, twisted and curved laterally, ending in a big curved spine enclaved in a sclerotized area that comprises the process ti, and converging basally to the medio-distal portion of the sclerite VS ( Figs. 17A, C–D ). Process ti extends from the fold df to cavity dc ( Figs. 17A–B, D–E ). Fold vdl conspicuous wrinkled, even when the phallus is everted ( Fig. 17F ). Sclerite VS robust, with ventral arms entirely downwards, and the dorsal arm extending till the process ti . This sclerite stands vertically when the phallus is everted or retracted ( Figs. 17B–C, E–F ). Processes mp.dl attached to the apical most portion of sclerite VS ( Fig. 17B ). Measurements (mm). Males. Total size. 18.5–23.2; Pronotum. 7.2–8.4; Width of pronotum. 5.9–6.9; Hind femur. 13.8–17.6; Tegmina. 3.9. Females. Total size. 25–29.5; Pronotum. 8–8.5; Width of pronotum. 6.7–7.2; Hind femur. 17–19; Ovipositor. 9.2–9.3. Chromatic pattern. When dead and dried, body light brown ( Figs. 14A–B ; 19A–B ); when preserved in alcohol, yellowish. A lighter band extends from the pronotal disk anterior border to the tenth tergite posterior border ( Figs. 14B ; 19B ). Lighter macules are present on both sides of all femora; all leg spines black or dark brown-tipped ( Figs. 15A–B, D–E, G–H ). When the specimen is alive, general color of body reddish or reddish-brown, with black marks on the lateral lobes of the pronotum ( Fig. 18 ).
