Etymology.

The name Edough (Djebel Edough), designating the prominent mountain massif overlooking the city of Annaba, is thought to derive from undocumented Berber (Amazigh) roots. In antiquity, it was referred to as Mons Pappua by Procopius who describes it as a Numidian stronghold, and as Mons Giddaba by Saint Augustine.

Descriptions.

Nymph. Body length of final instar, excluding caudal filaments, up to 7 mm for female; male nymphs unknown. Cerci as long as body length.

Coloration. General coloration medium brown; dark brown between ocelli, light brown in front and on the clypeus (Fig. 22 A View Figure 22 ), especially in young nymphs (Fig. 22 B View Figure 22 ). Antenna with pedicel dark brown, scape greyish brown and filament light brown, more or less entirely whitish in young nymphs. Pronotum medium brown, washed with dark brown sub-laterally and with a dark brown M-shaped macula in middle, lateral margins whitish; mesonotum medium brown, with dark brown maculae; lateroparapsidal sutures dark brown. Legs light to medium brown; femora dark brown in mature nymphs; tibiae medium brown, with dark brown apex in mature nymphs; tarsi light brown to yellowish. Abdominal tergites dark brown to greyish brown, with two lighter maculae medio-anteriorly, especially well visible on segments I – VII in young nymphs (Fig. 22 B View Figure 22 ); maculae less visible in mature nymphs (Fig. 22 A View Figure 22 ). Sternites medium brown in the middle, posterior margin underlined with dark brown laterally, nervous ganglia hardly visible. Cerci and paracercus light brown at base, whitish distally, without dark banding.

Head. Labrum rectangular, 1.75–1.79 × wider than long (Fig. 22 C View Figure 22 ); dorsal surface covered distally with scattered stout setae; anterior margin with a row of stout, long and spatulate setae medially; emargination flared, U-shaped with flat denticles; ventral surface with two bunches of stout setae medially. Mandibles similar to other Habrophlebia species, incisor with 3 teeth, the lowest of left mandible with a clear indentation at base (Fig. 22 D View Figure 22 ), kinetodontium with 3 teeth, 17–22 long and thin setae below mola of right mandible (Fig. 22 E View Figure 22 ). Maxilla stocky, subapical row of 7 or 8 pectinate setae (Fig. 22 F View Figure 22 ); maxillary palp with three segments, segment 1 and 2 subequal in length, and longer than segment 3; segment 3 triangular 1.41–1.75 × longer than wide at base; setae on the dorsal surface of segment 2 feathered (Fig. 23 B View Figure 23 ). Hypopharynx with highly developed superlinguae terminated by a membranous digitation (Fig. 23 A View Figure 23 ). Labium with rhomboid glossae, outer margin and apex covered by short, broad setae; paraglossae enlarged laterally, covered with fine and long setae on dorsal surface; with long, thick setae on the outer margin; labial palp with three segments, inner margin of segment 1 highly dilated near the middle, about 1.35 × longer than maximum width, segments 2 slightly shorter than segment 3, segment 2 ca. 0.67 × length of segment 1, and segment 3 ca. 0.74 × length of segment 1; segment 3 ca. 1.8–2.0 × longer than wide at base, conical shape and with 4–7 stout and long, simple setae on dorsal surface (Fig. 22 G View Figure 22 ). Submentum with numerous long, stout and pointed setae laterally; ventral surface with few long, stout and pointed setae (Fig. 22 G View Figure 22 ).

Thorax. Pronotum with anterior corners bearing few long and pointed setae laterally, and 4–6 stout and strong setae dorsally. Anterior margin of pronotum with numerous stout setae (Fig. 23 C View Figure 23 ). Fore legs femora elongated, ca. 2.75 × longer than wide, outer margin and upper surface covered with long, entire and pointed setae (Fig. 23 D View Figure 23 ); fore tibiae length 0.95 × femora length, outer margin without or with few thin and long setae, inner margin with several rows of long stout, entire or feathered setae; tarsi 0.6 × length of tibiae, outer margin with few long and thin setae, inner margin with long, pointed and feathered setae. Middle legs similar to fore legs, femora ca. 3.2 × longer than wide (Fig. 23 E View Figure 23 ), dorsal surface of femora with more numerous and slightly longer stout, entire or slightly feathered, pointed setae; tibiae length 0.92 × femora length; tarsi 0.45 × length of tibiae. Hind legs with femora 3.5 × longer than wide (Fig. 23 F View Figure 23 ), dorsal surface covered with stout, long, pointed, feathered setae (Fig. 23 G View Figure 23 ); tibiae length 0.94 × femora length, outer margin with numerous stout, pointed and entire setae; inner margin with stout, pointed and feathered setae; tarsi 0.42 × length of tibiae, outer margin with long and thin setae, inner margin with long, stout, pointed and entire setae. Claws of all legs slightly hooked, with 15–17 denticles that decrease in size from the apex to the tarsus (Fig. 23 H View Figure 23 ).

Abdomen. Posterolateral expansions only on segments VIII and IX. Posterior margin of tergite IX with triangular, narrow, pointed spines, ca. 2.5–3 × longer than wide at base (Fig. 24 A View Figure 24 ); tergite VIII with triangular, narrow spines 1.5–2 × longer than wide (Fig. 24 B View Figure 24 ); tergite VII and VI with a mix of short, narrow spines and minute, needle-shaped spines (Fig. 24 C, D View Figure 24 ); tergite V with minute needle-shaped spines (Fig. 24 E View Figure 24 ); tergites I – IV with barely visible spines. Gills present on segments I – VII; all gills elongated with long filaments; dorsal lamella bearing 8–10 filaments, ventral lamella with 4–5 filaments.

Imagos. unknown.

Eggs (extracted from mature female nymphs) ovoid, ca. 175–185 µm × 70–80 µm, with longitudinal ribs non-punctuated, long and entire, most of them not running from one pole to the other (Fig. 25 A View Figure 25 ). Ribs relatively narrow, ca. 2.5–3.0 µm in width. Micropyle in equatorial area (Fig. 25 B View Figure 25 ).
