Etymology. Dedicated to the memory of the social leader Edith del Consuelo Santos Jiménez, murdered in 2014, in the Chichimene village, Acacias, Meta, for her defense of the environment and the people of the oil sector.

Type material. Holotype. Male. Colombia, Meta, Acacias, Vrd. La Esmeralda, Finca La Bonita. 3.972 260, -73.726315. 514 m. 21 April 2004. J. Molano ( CAUD) . Paratype. Male, same data as holotype.

Description. Male. Large size for the genus ( Fig. 1A, B ). Coloration. Head, thorax and abdomen dark brown; legs and ventral surface of body yellowish brown. Head with bands alternating shades of brown; eyes black with depigmented ommatidia in the supra-internal region; ocelli and mouthparts ocher, labial palps and jaws yellow; translucent tegminae with yellow venation. Head. Rounded and as wide as the pronotal disc; frons between antennal cavities 1.5 times as wide as scape; ocelli moderately large and located almost on one transverse line, median ocellus transverse and lateral ones round. Maxillary palp with five palpomeres, first and second shorter, third larger than fourth, fifth-largest, enlarged, apex truncated and grooved ( Fig. 2A ). Thorax. Pronotum pubescent, with thicker bristles at the edges; anterior edge of the pronotal disc with concave central portion, straight posterior edge; midline crossing from the anterior to the posterior edge of the pronotal disc, and on each side, a mark in leaf form, no varying in color with the rest of the pronotum. Legs. Pubescents; fore and mid legs similar; fore tibia with one external and two internal apical spurs, outer tympanum large and ovoid, inner tympanum very small and rounded; hind tibia with seven pairs of dorsal spines; hind basitarsus with two rows of dorsal denticles, seven inner and eight outer, two apical spurs, the internal longer than the external. Wings. Tegmina ovoid and covering only the first abdominal segment and the base of the second one ( Fig. 2B ); stridulatory file with 101 teeth ( Fig. 2C ), basal area reduced, A3 vein very reduced almost covering the anterior edge of the pronotum when the tegmina is at rest, harp with two diagonal veins, the chordal area with veins Cu2 and 1A parallel and arcuate, veins 2A and 3A parallel to the tegmen edge, two small veins connecting the Cu2 vein to the mirror; apical area reduced and reticulate; mirror divided by a vein very close to the inner-lower edge ( Fig. 2B ). Hind wings reduced. Abdomen. Epiproctus with moderately elongated and rounded posterior edge; subgenital plate rectangular, longer than wide and with a rounded apex. Genitalia. Pseudepiphallic median lophi elongated and lanceolated in ventral and dorsal view ( Fig. 3A, C ), moderately flared, with a deep U-shaped notch at the apex, lateral edges with abundant hairs; pseudepiphallic parameres slender and shorter than the median lophi, apex truncated and ondulated ( Fig. 3A, B ); lateral lophi shorth and hook-shaped; ectophallic fold ribbon-shaped, narrow and sticking out between the pseudepiphallic median lophi and parameres, apex lanceolated ( Fig. 3A ); arc narrow, as a plate up-curved dorsally ( Fig. 3C, D ); endophallic cavity membranous and ovoid ( Fig. 3C, D ); quadrangular rami connected in the posterior portion ( Fig. 3A–D ).

Female. Unknown.

Measurements (mm): LB: 11–12. Pr: 4–4.5. Teg.: 6–6.5. HF: 14. HT: 10.

Comparison. This new species is more similar to Caribbean species such as A. (U.) amolgos Otte & Perez-Gelabert, 2009, A. (U.) gnomus Otte & Perez-Gelabert, 2009 and A. (U.) nigua Otte & Perez-Gelabert, 2009, than the continental species of the subgenus Urogryllus . It is distinguished from A. (U.) amolgos because the tegmina reach the base of the second abdominal tergite and the apex of the median lophi is lanceolate and without undulations on the lateral edges of the new species, in contrast, A. (U.) amolgos the tegmina cover slightly more than half of the abdomen and the apex of the median lophi is narrow and wavy. A. (U.) edithsantosum n. sp. differs in the incision of the median lophi, which is deeper and wider to A. (U.) gnomus. The new species has the ectophallic fold of medium size, but in A. (U.) nigua is elongated, in lateral view the median lophi and lateral lophi of pseudepiphallus looks altogether like a snout, and between these the ectophallic fold emerges like a tongue. A. (U.) edithsantosum n. sp. differs from the three mentioned species, in its larger size, brown color of the head, and the pseudepiphallic median lophi is covered with hairs (as the species of the subgenus Pilosogryllus), in contrast, the other species are of medium to small size, the head is black, and the pseudepiphallic median lophi is hairless.
