( INPA ). Male. Head. Projection of the triangular fastigium-vertex and equivalent in size to the anterior projection of the pronotal disc, in lateral view ( Fig. 3D ). Thorax . Pronotal disc with anterior projection acuminate and slightly curved backwards, in lateral view; wide posterior projection with a small apical spine ( Fig. 3D ). Mesobasisternum and metabasisternum triangular-shaped, anteriorly slightly concave ( Fig. 2E ). Lateral lobes of mesobasisternum anterolaterally, laterally and posteriorly convex, posterolaterally forming an angle of 120° ( Fig. 2E ). Lateral lobes of metabasisternum anterolaterally convex, laterally straight and posteriorly slightly convex, posterolaterally forming an angle of 140° ( Fig. 2E ). Wings . Left stridulatory file slightly curved; teeth in apical half small and more spaced apart ( Fig. 5A ). Total length of left stridulatory file 2.6 mm , greater vein width of 0.5 mm and a total of 54 teeth ( Fig. 5A ). Right stridulatory file slightly curved; teeth basal and apical minor ( Fig. 5B ). Total length file of 1.9 mm , widest vein of 0.3 mm and total of 45 teeth ( Figs. 5B ). Abdomen . Cercus apically forked, with the external projection curved, narrow and with acuminate apex ending in a slightly curved spine; Slightly curved internal projection, with serrated inner face and acuminate apex ( Figs. 3I–J ). Space concave between the base of stylus ( Figs. 3I–J ). Internal male genitalia. Not examined. Coloration. Based on photos of preserved specimen ( Fig. 3 ). Body yellowish-brown. Eyes dark brown. Female. unknown. Geographical records. Brazil : Roraima (Fig. 10). Measurements (mm). Holotype ♂ : TL: 22; TegL: 34; TegH: 9,5; WF: 3,2; PL: 5; PH : 4; FF: 5,5; FT: 7,2; MF: 8; MT: 8,5; HF: 20; HT: 22; Lplac: 3; LC: 2. Natural history notes. The forest at the collecting site and in general between 1400-1600m on the north slope of Serra do Sol is tall ( 15-20m canopy), made up mostly of straight, narrow-trunked trees with heavy loads of epiphytic mosses. The soil, vegetation, and atmosphere were extremely humid at this elevation during the expedition, nearly constantly bathed in clouds when not actually raining.
