All femora entirely ochre, without the ‘ zebra’ pattern (Fig. 2 A – C, G – K). Males dorsally with head, pronotum, tegmina, and first abdominal tergite black (Fig. 1 A – E); without stridulatory apparatus (Fig. 1 E). Comparatively, all the other known species of Zebragryllus are easily distinguished for having stridulatory apparatus on the male tegmina. Male genitalia: pseudepiphallic median lophi elongated, conspicuously produced hind- and upwards, very narrow, and apically acute, ventrally with a sharp keel. Pseudepiphallic lateral lophi acute. Pseudepiphallic paramere surpassing the lateral lophi; in ventral view, slightly arched. Ectophallic fold very thin, not reaching the level of the pseudepiphallic paramere apex (Fig. 3 A – D). Female with the black coloration extending till the second abdominal tergite (Fig. 4 A – D); remaining tergites dark brown; ovipositor straight and almost as long as the hind femora (Fig. 4 A, H – I).

9D21FC4B5A46B36740BA237FFC1B9170.taxon	discussion	Remarks Zebragryllus aphonus Tavares, Oya & Cadena-Castañeda sp. nov. has quite a unique feature. It is the only known species of the genus in which the male has no stridulatory apparatus. The different development levels of the tympana are also singular to this species. These two characteristics may be adaptations to the caves in which they were found. Still, it is hard to ensure since no phylogenetic study was made and ecological data are lacking. The shape of the pseudepiphallic median lophi is similar to that of Z. nauta. However, it differs by the presence of conspicuous pseudepiphallic lateral lophi, which are very reduced and almost inconspicuous in Z. nauta. These two species may be related. We believe this species is facultative to a cave-dwelling way of life or caviculous (sensu Desutter-Grandcolas et al. 1998), foraging on forest ground during the nights and passing the day inside the caves or cavities at ground level. We believe in this assumption since adult and immature stages were found inside caves as field work was carried out during the day. This species may also inhabit or take refuge in pores or voids on the soil, characteristic microhabitats of the environment where it was collected. The structure of the landscape is known as Banded Ferruginous Formations, which are iron formations composed of alternated bands of jaspilite and ore bodies rich in iron. In this area, extensive iron ore plateaus are formed, comprising superficial ferrugineous breccia, also known as canga formation. A metallophilic savannah covers the canga formations on the plateaus and mountains, while typical tropical vegetation of the Amazon rainforest covers the slopes. The highly porous canga formations result from the removal of silica and carbonates due to the tropical rains, which causes the dissolution and chemical change found in iron ore, forming several interconnected small spaces in the canga formations – the voids (Ferreira et al. 2018). Zebragryllus aphonus Tavares, Oya & Cadena-Castañeda sp. nov. was collected in seven caves in the municipality of Canaã dos Carajás, located in the east region of Pará State, Brazil (Fig. 16 A – C). The caves are coded as S 11 C- 0033, S 11 C- 0037, S 11 C- 0050, S 11 C- 0066, S 11 C- 0092, S 11 C- 0110, S 11 C- 0121. They are situated in the Amazon rainforest and are part of the federal conservation unit “ Floresta Nacional de Carajás ” (FLONA) (Carmo & Kamino 2015). They are located within the “ Grão-Pará ” geological group, known for its iron-ore lithology. This region is popularly known as “ Serra dos Carajás ”, which comprises vast plateaus separated by depressions in the landscape, dividing it into three regions: Serra Norte, Serra Leste, and Serra Sul (Carmo & Kamino 2015). The seven caves where the specimens were collected are situated in the “ Serra Sul ” plateaus region (Fig. 16).	en	Tavares, Gustavo Costa, Oya, Beatriz Harumi Kondo, Cadena-Castañeda, Oscar J., Oliveira, Marcus Paulo Alves de, Castro-Souza, Rodrigo Antônio (2024): New species and records of Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 (Orthoptera: Gryllidae: Gryllinae) from the Brazilian Amazon rainforest.

Marked seasonality and highly dynamic vegetation, comprising a mosaic of Cerrado, Amazon rainforest, and ecotonal forest vegetations, with high tree mortality and turnover levels, characterize this zone (Marimon et al. 2014; Morandi et al. 2015; Passos et al. 2018; Marques et al. 2020).	en	Tavares, Gustavo Costa, Oya, Beatriz Harumi Kondo, Cadena-Castañeda, Oscar J., Oliveira, Marcus Paulo Alves de, Castro-Souza, Rodrigo Antônio (2024): New species and records of Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 (Orthoptera: Gryllidae: Gryllinae) from the Brazilian Amazon rainforest.

9D21FC4B5A53B3784387239FFB319329.taxon	diagnosis	Diagnosis This female is similar to that of Z. wittoto, Z. guianensis, and Z. nouragi by the ‘ zebra’ pattern on the hind legs (Figs 10 A – B, 11 J – K). The fore and mid legs have only a few whitish areas on the base of the femora and dorsal surface of the tibia (Fig. 11 E – F, H – I). The tympanum is widely open on the outer face proximal portion of the fore tibia (Fig. 11 E, G). However, it differs from the species mentioned above in the longer tegmina, reaching up to the second abdominal tergite (Fig. 10 C – D), which is more similar to Z. nauta. The first two segments of maxillary palpi are small and subequal in length; the third and fourth are as long as the first and second together; the fifth is longer than any other segment, with the ventral margin slightly arched and the medio-distal portion obliquely truncated, dorsal margin straight and the apex rounded. The only whitish area of the maxillary palpi is the ventral surface of the mediodistal portion; the remaining is dark (Fig. 11 D). The abdomen is mostly black but has whitish bands on the anterior and posterior margins of each tergite (Fig. 10 A – B). The supra-anal plate is subtriangular, with a distal margin rounded (Fig. 10 E). The subgenital plate is similar to that of Z. nouragi, with the posterior margin sinuous in lateral view and concave in ventral view (Fig. 10 F – G). The ovipositor is straight and very short, shorter than the hind tibia, with a triangular apex (Fig. 10 A – B, 10 H – I), similar to Z. guianensis. The copulatory papilla is quite unique, with an ovoid shape, laterally sinuous, and a more membranous dorsal portion (Fig. 11 A – B).	en	Tavares, Gustavo Costa, Oya, Beatriz Harumi Kondo, Cadena-Castañeda, Oscar J., Oliveira, Marcus Paulo Alves de, Castro-Souza, Rodrigo Antônio (2024): New species and records of Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 (Orthoptera: Gryllidae: Gryllinae) from the Brazilian Amazon rainforest.

9D21FC4B5A51B37D438727A4FECB96BF.taxon	diagnosis	Diagnosis This female is very similar to that of Z. aphonus Tavares, Oya & Cadena-Castañeda sp. nov. in the body shape (Fig. 12 A – B). Still, it is quickly differentiated in the legs darker chromatic pattern (Figs 12 A – B, 13 E – H). This species does not have the genus characteristic ‘ zebra’ pattern on the hind legs or abdomen either (Figs 12 A – B, 13 E – H). Other differences easily noted are the longer tegmina (Fig. 12 A – D), the large tympana on the outer faces of the fore tibia (Fig. 13 E, in detail), and the tiny tympana on the inner face (Fig. 13 F, in detail). The fore and hind (mid legs lost) legs have no whitish areas (Fig. 13 E – F). The maxillary palpi are similar to the species described above but differ by the slightly concave fifth segment’s dorsal surface and the slightly longer truncated-medio-distal portion (Fig. 13 D). The abdominal tergites are dark brown, with no whitish areas (Fig. 12 A – B). The supra-anal plate is subtriangular, with a distal margin rounded, somewhat longer and wider than in Z. aphonus Tavares, Oya & Cadena-Castañeda sp. nov. (Fig. 12 E). The subgenital plate is similar to that of the female from Cayenne in Desutter-Grandcolas et al. (2014) (see Desutter-Grandcolas et al. 2014, Fig. 6 Q – R), with the distal margin convex in lateral view and concave in ventral view (Fig. 12 F – G). The ovipositor is also similar to that of Z. aphonus Tavares, Oya & Cadena-Castañeda sp. nov. but darker (Fig. 12 H – I), and almost straight, with a triangular apex bearing scale-like texture on the dorsal surface (Fig. 12 J – K). The dorsal valves dorsally sulcated (Fig. 12 H – I). The copulatory papilla is also similar to the female from Cayenne in Desutter-Grandcolas et al. (2014) (see Desutter-Grandcolas et al. 2014: Fig. b’ – d’) but is more cylindrical and not dorsoventrally flat, like in most species of the genus (Fig. 13 A – C).	en	Tavares, Gustavo Costa, Oya, Beatriz Harumi Kondo, Cadena-Castañeda, Oscar J., Oliveira, Marcus Paulo Alves de, Castro-Souza, Rodrigo Antônio (2024): New species and records of Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 (Orthoptera: Gryllidae: Gryllinae) from the Brazilian Amazon rainforest.

9D21FC4B5A51B37D438727A4FECB96BF.taxon	description	Description MEASUREMENTS (mm). ♀. TL: 9.5; LP: 1.5; WP: 2.7; Tg: 2.3; HF: 6.5; HT: 4.8; Ov: 6.5. New records This is the first time that Zebragyllus has been recorded in Brazil. Two new species are being added to the genus, and two known species are recorded: Z. guianensis (Figs 14 A – H, 16 A) and Z. nouragui (Figs 15 A – H, 16 A). These two species were only known from their type locality, in French Guiana, where they live in sympatry, and here we extend their distribution (Fig. 16 A). Five males and five females of Z. guianensis were collected in the Floresta Nacional de Caxiuanã, municipality of Melgaço, Pará State. Two males, two adult females, and one juvenil specimens of Z. nouragui were collected in Juruti, Pará State. It is plausible that these species occur in Brazil as these two localities are in Northern Pará State, near the boundary between Brazil and French Guiana, but on the other side of the great Amazon River. Floresta Nacional de Caxiuanã is about 630 km south of the Réserve Naturelle Nationale des Nourages (type locality), and Juruti is about 770 km southwest (Fig. 16 A). The other species of Zebragryllus are only recorded in Peru and Colombia. So we expect these known species and new ones to also occur in Brazil as their distribution is unexplored. The males of Z. nouragui studied here have a different chromatic pattern of the hind femora, a variation of the populations described by Desutter-Grandcolas et al. (2014). The paired whitish oblique bands described for the species, like those seen in the female hind femora (Fig. 15 C), are absent, and only the ventral whitish band is displayed (Fig. 15 A). Species of Zebragryllus may occur in very low populations since just a few specimens were collected, even in considerable collection efforts, like in Floresta Nacional de Caxiuanã. This site was monitored for two years, with monthly armed pitfall traps in a 2 - acre area. The area was divided into several parcels of 1 m ², each with a pitfall trap installed in the center. Even so, only ten specimens of Z. guianensis were captured.	en	Tavares, Gustavo Costa, Oya, Beatriz Harumi Kondo, Cadena-Castañeda, Oscar J., Oliveira, Marcus Paulo Alves de, Castro-Souza, Rodrigo Antônio (2024): New species and records of Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 (Orthoptera: Gryllidae: Gryllinae) from the Brazilian Amazon rainforest.
