The name “Ghora” is derived from the Coot (Fulica atra), known locally as “ Ghor ”, whose conspicuous white frontal shield evokes the image of a snow-capped peak. Mount Ghora (Djebel Ghora), situated on the Algerian – Tunisian border, takes its name from this association and forms part of the Kroumiria massif. Descriptions. Nymph.

General coloration medium brown; light brown between compound eyes and antennae. Upper portion of male eyes light brown to orange (Fig. 2 A). Antenna with scape and pedicel greyish brown, filament yellowish. Pro- and mesonotum medium brown, with light brown maculae, on medium; lateroparapsidal sutures dark brown. Legs light to medium brown; dorsal surface of femora darker; tibiae and tarsi light brown to yellowish. Abdominal tergites medium brown with a sagittal line paler; distal half of each tergite darker, sometimes with two elongated light maculae medio-anteriorly, on segments I – VI, especially in younger nymphs. Sternites light to medium brown, nervous ganglia well visible. Cerci and paracercus medium brown at base, lighter distally, rather uniform in color, without apparent banding. Head.

Hypopharynx with highly developed superlinguae terminated by a membranous digitation (Fig. 2 F). Labium with rhomboid glossae, outer margin and apex covered by short, broad setae; paraglossae enlarged laterally, covered with fine and long setae on the dorsal surface; with long, thick setae on outer margin; labial palp with three segments, inner margin of segment 1 highly dilated near the middle, about 1.20 × longer than the maximum width, segment 2 as long as segment 3, ca. 0.8 × length of segment 1; segment 3 ca. 1.75–1.80 × longer than wide at base, conical shape and with 7–8 stout and long, simple setae on dorsal surface. Submentum with numerous long, stout and pointed setae laterally; ventral surface with few long, stout and pointed setae (Fig. 2 G). Thorax. Pronotum with anterior corners bearing few long and pointed setae laterally, and 6–8 stout and strong setae dorsally. Anterior margin of pronotum with 3–5 stout setae laterally (Fig. 3 A). Fore legs femora elongated, ca. 2.65 × longer than wide, outer margin and upper surface covered with long, entire and pointed setae (Fig. 3 B); tibiae slightly shorter than femora, outer margin with sparse thin and long setae, inner margin with long stout and feathered or entire setae more numerous near apex; tarsi 0.55 × length of tibiae, outer margin with sparse long and thin setae, inner margin with long and pointed entire setae. Middle legs similar to fore legs, femora ca. 2.9 × longer than wide, dorsal surface of femora with more numerous and slightly longer stout and pointed setae (Fig. 3 C); tibiae slightly shorter than femora; tarsi 0.5 × length of tibiae. Hind legs with femora 3.4 × longer than wide (Fig. 3 D), dorsal surface covered with stout, long and short, pointed or rounded and entire (non-feathered) setae more or less in rows (Fig. 3 E); hind tibiae as long as hind femora, outer margin with scattered stout, pointed setae; inner margin with stout, pointed and entire setae (Fig. 3 F); tarsi 0.45 × length of tibiae, outer margin with few long and thin setae, inner margin with long, stout, pointed and entire setae.
