Description. Holotype Male.

Head. Head rounded, with frons and gena rough in frontal view; fastigium-vertex small and W-shaped, in frontal view; clypeus anterolaterally curved, laterally concave and posteriorly sinuous ( Fig. 1B View FIGURE 1 ). Globular eyes ( Figs. 1B–D View FIGURE 1 ). Scape rectangular and smooth; pedicel small and quadrangular ( Fig. 1B View FIGURE 1 ).

Thorax. Pronotal disc with several long and sharp projections, having six of them distinctly longer than others: one anterior, narrow, with shorter spines on it, diagonally turned toward the head ( Figs. 1C–E View FIGURE 1 ; 2A–C View FIGURE 2 ); two medial projections, shorter than anterior projection, laterally turned to outer side ( Figs. 1C–E View FIGURE 1 ; 2A–C View FIGURE 2 ); two posterolateral, wider than others, laterally turned to outer side, with anterior margin bearing a hook-shaped projection and posterior margin with shorter spines; and one posterior projection, shorter than the others, narrow, curved upwards and with tip posteriorly turned. Posterior region of pronotal disc with a series of short diagonal spines, laterally opposed, almost forming a crown of spines with posterolateral and posterior projections ( Figs. 1C–E View FIGURE 1 ; 2A–C View FIGURE 2 ). Lateral lobes of pronotum rough ( Fig. 1E View FIGURE 1 ). Mesobasisternum subrectangular-shaped, anteriorly straight and posteriorly convex ( Fig. 1H View FIGURE 1 ). Lateral lobes of mesobasisternum subtriangular-shaped, anterolaterally convex, laterally forming a round tip, posterolaterally and posteriorly convex ( Fig. 1H View FIGURE 1 ). Metabasisternum subrectangular-shaped, anteriorly straight and posteriorly slightly convex ( Fig. 1H View FIGURE 1 ). Lateral lobes of metabasisternum anterolaterally and laterally convex, posterolaterally straight, posteriorly slightly convex ( Fig. 1H View FIGURE 1 ). Wings. Tegmina elongated, curved over the abdomen, apex rounded and aspect rough. Apex of tegmina not exceeding the base of the cercus ( Fig. 1A View FIGURE 1 ). Left stridulatory file straight, with apical region slightly curved; teeth on basal half progressively short toward the base; apical teeth short; teeth narrow, asymmetrically positioned in rows, distance between each teeth shorter than a teeth width ( Fig. 3 View FIGURE 3 ). Total length of left stridulatory file 6.3 mm, greater vein width of 1.2 mm and a total of 99 teeth ( Fig. 3 View FIGURE 3 ). Legs. Fore femur straight, with apical region slightly curved, presence of five of triangular ventral spines, one pair apical acuminate spines and one small triangular spine apical on the dorsal margin, in lateral view ( Fig. 1F View FIGURE 1 ). Fore tibia straight, ventrally with basal curvature; ventral margin with a large recurved leaf projection and three pairs of smaller recurved projections; ventral margin apically with four pairs of small spines, in lateral view ( Fig. 1F View FIGURE 1 ). Mid femur straight, four ventral curved spines, one pair apical acuminate spines and one small triangular spine apical on the dorsal margin, in lateral view ( Fig. 1G View FIGURE 1 ). Mid tibia slightly sinuous with five pairs of small triangular spines and three pairs of small apical ventral spines, in lateral view ( Fig. 1G View FIGURE 1 ). Hind femur elongated, narrow and enlarged at basal half, with seven large ventral spines, one pair apical acuminate spines and one small triangular spine apical on the dorsal margin, in lateral view ( Figs. 1A View FIGURE 1 ). Hind tibia straight, narrow, with several large dorsal recurved projections ( Figs. 1A View FIGURE 1 ). All legs with short bristles ( Figs. 1A, F–G View FIGURE 1 ). Abdomen. Cercus short, wide, apically curved inward, slightly flattened dorsoventrally, with small spine inward. Subgenital plate subtriangular, laterally straight, with space concave between the base of stylus. Styli elongated and narrow; apex of styli not exceeding apex of cerci. Cerci with several large bristles ( Figs. 1I–K View FIGURE 1 ).

Internal male genitalia. Not examined.

Coloration. Described based on photos of live specimens ( Figs. 4 View FIGURE 4 and 5 View FIGURE 5 ). General body color of the specimens varies from dark brown, greenish-brown and yellowish-green, with patterns of light and dark asymmetrical spots, giving an appearance of tree bark with lichens. Apical region of the head dark-green. Eyes dark brown. Tegmina dark brown with light-green veins, with emphasis on the radiating veins. Tibia with a large median whitish stripe. Cercus light-green.

Female: Similar to male, except for the following features ( Fig. 6 View FIGURE 6 ). Wings. Anal veins unmodified for sound production. Abdomen. Cercus slightly curved with acuminate and inward curved apex, in dorsal view ( Fig. 6E View FIGURE 6 ). Cercus with long bristles. Ovipositor slightly curved; apex of ovipositor acuminate with small teeth on dorsal and ventral valve ( Fig. 6A View FIGURE 6 ). Coloration. Ovipositor dark brown with several asymmetrical dark green spots ( Fig. 6A View FIGURE 6 ).

Etymology. The epithet is in apposition, neblina = fog or mist, in reference to the local name given to the cloud forest in which this new katydid lives.

Geographical records. Colombia (Antioquia) ( Fig. 8 View FIGURE 8 ).

Type material. Holotype ♁. COLOMBIA, Jardín, Antioquia, Mesenia-Paramillo nature reserve, Station , 05°29’45”N – 75°53’20.7”W, 2.200 m, 18.IX.2022, Manual collection, L. Mazariegos col. ( CEUA). GoogleMaps Paratypes: Idem (2♁ and 1♀ CEUA).

Measurements (mm). Holotype ♁: TL: 15.5; TegL: 9.7; TegH: 3.2; PL: 4.8; FF: 7.9; FT: 11.3; MF: 8.2; MT: 9.4; HF: 13.2; HT: 16.9; Lplac: 3.3; LC: 1.9.

Paratypes 2♁: TL: 15.9–16.2; TegL: 10.4–10.8; TegH: 3–3.7; PL: 5.3–5.4; FF: 7.3–7.6; FT: 9.3–9.8; MF: 8.2– 8.8; MT: 10.4–10.5; HF: 13; HT: 15.6–16.2; Lplac: 3.4–3.5; LC: 2.7–2.8.

Habitat. The specimens were collected around the main station (2.200m) at the MPNR with secondary forest covered with abundant mosses (bryophytes). The specimens were active at night and we suggest that this new genus of katydid lives and camouflages itself within the moss covered vegetation.
