Etymology.

The name of El Kala derives from the Arabic al-Qalʿa (“the fortress”), a reference to its strategic role through history. During the French period it was known as La Calle, while in antiquity it was recorded as Thinisa in Numidia.

Abdominal tergites medium brown with three pairs of lighter maculae, especially well visible on segments I – VI (Fig. 12 A View Figure 12 ); posterolateral angles and posterior margin of tergites I – VIII dark brown. Sternites medium brown to greyish brown, nervous ganglia well visible (Fig. 12 B View Figure 12 ). Cerci and paracercus medium brown at base, lighter distally, dark banding slightly visible every two segments proximally.

Mandibles similar to other Habrophlebia species, incisor with 3 teeth, the lowest of the left mandible with a clear indentation (Fig. 12 D View Figure 12 ), kinetodontium with 3 teeth, 14–15 long and thin setae below mola of right mandible (Fig. 12 E View Figure 12 ). Maxilla stocky, subapical row of 5 or 6 pectinate setae (Fig. 12 F View Figure 12 ); maxillary palp with three segments, segment 1 and 2 subequal in length, and longer than segment 3; segment 3 triangular 1.51–1.71 × longer than wide at base; all setae on palp segments stout and entire. Hypopharynx with highly developed superlinguae terminated by a membranous digitation (Fig. 12 G View Figure 12 ). 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 the outer margin; labial palp with three segments, inner margin of segment 1 highly dilated near the middle, about 1.15–1.20 × longer than the maximum width, segments 2 0.85 × length of segment 1, segment 3, ca. 0.75 × length of segment 1; segment 3 ca. 1.7–1.8 × longer than wide at base, conical shape and with 5–7 stout and long, simple setae on dorsal surface. Submentum with numerous long, stout and pointed setae laterally and on ventral surface (Fig. 12 H View Figure 12 ).

Thorax. Pronotum with anterior corners bearing numerous long and pointed setae laterally, and dorsally. Anterior margin of pronotum with a row of stout setae (Fig. 13 A View Figure 13 ). Fore legs femora stocky, ca. 2.1 × longer than wide, outer margin and upper surface covered with long, entire and pointed setae (Fig. 13 B View Figure 13 ); fore tibiae slightly shorter than femora, outer margin with thin and long setae, inner margin with long stout and feathered or entire setae especially near apex; tarsi 0.55 × length of tibiae, outer margin with long and thin setae, inner margin with long and pointed entire setae. Middle legs similar to fore legs, femora ca. 2.5 × longer than wide, dorsal surface of femora with numerous and long, stout and pointed setae; tibiae and femora of subequal length; tarsi 0.5 × length of tibiae.

Imagos. Male imago in poor condition, only mid- and hind legs and abdomen preserved. Mid and hind legs coloration as in nymphs, whitish with apex of femur brownish. Femur / tibia / tarsi ratio in mid leg: 1 / 1.3 / 0.06 / 0.05 / 0.05 / 0.1; hind leg: 1 / 1.3 / 0.1 / 0.08 / 0.06 / 0.1. Mid- and hind claws dissimilar, one paddle-like and one hooked. Abdomen. Coloration similar to male nymphs. Styliger plate medium brown, dark brown along the margins, first segment of the gonopods medium brown, segments 2 and 3 yellowish brown.
