Etymology. This species is dedicated to Diego Matheus de Mello Mendes, a dear friend of the first author, in recognition of his significant contributions to the Orthoptera of Brazil, especially in the Amazon region of such a wonderful country.

Description. In addition to the characters of the genus: Female. Medium to large-sized compared to the other species of the genus ( Fig. 1 View FIGURE 1 ). Body predominantly dark brown, forelegs yellowish-brown, dactyls black with ocher base ( Figs. 1A View FIGURE 1 , 2A View FIGURE 2 ), tympanum whitish ( Fig. 2B View FIGURE 2 ). Mid-legs yellowish, hind legs with faded brown spots on an ocher background ( Fig. 1B View FIGURE 1 ). Tegmina and hindwings yellowish-white, with yellowish-brown veins ( Fig. 2D View FIGURE 2 ). Head slender with mouthparts ending in a conical shape when closed and covered by clipeus and labrum. Ovoid ocelli, medium size, greatest diameter 0.20–0.21 mm.; interocellar distance 1.5 times the maximum width of one of the ocelli. Ocellar-ocular distance less than one ocellar length; interocular distance slightly greater than the length of compound eyes ( Fig. 2A View FIGURE 2 ). Thorax. Pronotum elongated oval, almost twice as long as wide ( Fig. 1A View FIGURE 1 ). Legs. Forefemur 1.8 times longer than wide. Process of fore femur almost as long as wide, apex rounded ( Figs. 2B,C View FIGURE 2 ). Tympanum ovoid and elongated occupying 80% of the tibia base ( Fig. 2B View FIGURE 2 ). All dactyls pointed, the longest and most prominent being the mobile dactyls, with similar length; immobile dactyls of the tibia shorter than the articulated dactyls, the smallest being the ventral one ( Fig. 2B View FIGURE 2 ). Tarsal dactyl with rounded apex, the proximal or ventral dactyl is the longest, with the ventral margin uniformly curved; middle or dorsal dactyl as long as a quarter of the length of the ventral dactyl, with slightly wavy posterior edge; last tarsomere not modified, reduced, cylindrical and with two small distal claws ( Fig. 2C View FIGURE 2 ). Wings. Tegmina covering up to the second tergite, vein A2 not forked, anal 1 and 2 regions with numerous cross-veins, anal region 1 with three or four cross-veins; first cubital area with 2 or 3 crossveins ( Fig. 2D View FIGURE 2 ). Hind wings surpass the length of the abdomen ( Fig. 1 View FIGURE 1 ). Abdomen. Edges of the dorsal groove of the last tergites with conspicuous setae, reddish and turning inwards. Epiproct triangular, wider than long. Subgenital plate wider than long and with a rounded edge.

Male. Unknown.

Measurements (in mm). Tl: 24–29, Ol: 0.20–0.21, Id: 0.30–0.32, Ood: 0.12–0.15, Pl: 4–7, Pw 4.5–6: Pf: 0.9, Teg: 8–9, Hf: 4.5–5, Ht: 3–3.5.

Comparison. G. rehni is the closest known species to the new species. The new species differs from G. rehni by a more elongated pronotum, ovoid ocelli, pointed dactyls, and tegminal venation. In contrast, G. rehni has circular ocelli; moderately elongate pronotum; dactyls with the apex not sharp, and tympanum occupies 90% of the tibia base. Anal region 1 with five or six cross-veins; first cubital area with four cross-veins vs. anal region 1 with three or four cross-veins; first cubital area with 2 or 3 cross-veins to the new species.
