Body large for this genus, shining, and relatively uniformly colored. General coloration brown; rostrum, base of legs, posterior femoral apex, tibial apex, pleura and sternites creamy light brown ( Figs. 15–16 ). Head : ovoid; rostrum wide, with a pair of rounded and oblique margins, as wide as 1.5 times the antennal scape width; vertex fastigium delimited by two rounded margins, moderately divergent towards the sides and frontally truncated, being two times as wide as antennal scape; ocelli equidistant, rounded, the frontal one being slightly bigger and prominent than lateral ones ( Fig. 17 ). Thorax : thoracic tergites similar to abdominal ones; pronotum tubular without humeral sinus, lateral lobules rectangular and anterior and posterior margin straight ( Fig. 18 ), meso- and matanotum with similar shape as pronotum but shorter and with latero- inferior margins rounded; mesonotum notoriously wider than pro- and metanotum ( Fig. 19 ). Legs : anterior and medial pairs slender, third pair with femora well developed for jumping; anterior tibiae with tympani well developed in both sides, oval and medium in size (slightly bigger than in the other previously described species); tibial armament — d2a, vi4 , ve4, v2 a / 2da, vi3 , ve3, vsa2, va2 / d10e, d 9i , d2sa 6a. Abdomen : tubular; tergites with posterior margins rounded; eighth tergite with posterior margin similar to first seven tergites; ninth tergite with posteromedial margin pronounced and rounded; tenth tergite without being covered notoriously by ninth tergite ( Figs. 20–21 ), hooks thick and conical, producing outwards and slightly resting on ninth tergite prolongation; cerci slender and very long, being six times longer than paraprocta; epiproctum ovoid, almost as wide as long, with apex rounded and protruding below membranous area of tenth tergite; paraprocta sub cylindrical, curving steeply upwards close to apex without expanding, armed with a sharp spine located in the internal area above the meso- distal area where the paraproctum curves ( Figs. 22–23 ); subgenital plate slightly thinning from the base towards the apex, armed on each side of the apex with cylindrical styli, notch shallow “U” shaped ( Fig. 22 ). Female: Similar to males, color pattern similar to male holotype except darker, like in the male Paratype ( Figs. 24–26 ). Epiproctum sub-triangular, paraprocta without processes; subgenital plate triangular, very wide at base, thinning progressively towards apex and with a small distal notch ( Fig. 27 ); ovipositor as long as a fourth of posterior femoral length, curving upwards smoothly and with distal part with shallow sub apical concavity on dorsal edge of upper valves ( Fig. 28 ). Measurements (in mm.): Holotype : LB: 30. Pr: 7. HF: 26.5. HT: 20. Paratypes : Male / Female: LB: 27/34. Pr: 8/9. HF: 26.5/28. HT: 29/29.5. Ov: 12. Etymology. Named in honor of our friend Francisco Asturias, he is one of the leading conservationists in Guatemala , working in the field to protect Guatemala’s largest tropical jungle. Comparison . Because of its coloration this species appears more like G. anderi and G. beretka but differs in the light brown spots one the apex of posterior femora. Ninth tergite prolongation and disposition of hooks is more similar to G. anderi , differing in having wider hooks in the new species and paraprocta not expanded in the meso distal region; subgenital plate styli are not as wide as in G. anderi either. In the new species the ovipositor is very similar to the one in G. beretka (described as Glaphyrosoma sp. in Gorochov & Cadena-Castañeda, 2016 ), presenting the same particular shape of the apex of the dorsal valve. The apex of female subgenital plate presents a notch very similar to the one in G. pushenkovi , differing in that the subgenital plate in the new species is much wider and shorter.
