Description. Nymph.

Coloration and dimensions. Body length of final instar, excluding caudal filaments, 5 to 6 mm for male and 5.5 to 6.5 mm for female. Cerci as long as body length. General dark brown coloration with greyish to light brown markings mainly on abdominal terga. The whole cuticle is shagreened.

Head. General coloration light brown; paler area around the compound eyes and lateral ocelli; between ocelli, a dark brown mark not reaching the clypeus distally, and extending laterally in front of the compound eyes in males; vertex sutures light brownish, barely visible ( Fig. 2A View FIGURE 2 ). Upper portion of male compound eyes red brownish. Antenna with pedicel brownish, scape and filament yellowish.

Labrum rectangular ( Fig. 3A View FIGURE 3 ), 1.7–1.9 x wider than long; dorsal surface covered distally with scattered stout setae, proximally with long and thin setae; anterior margin with a row of stout, long and spatulate setae medially; emargination narrow, U-shaped with ca eight flat denticles; ventral surface with two bundles of stout, long setae medially.

Mandibles similar to other Habrophlebia species ( Fig. 3B View FIGURE 3 ). 7–10 long and thin setae below the mola of the right mandible.

Maxilla stocky, subapical row of 7–8 pectinate setae ( Fig. 3C View FIGURE 3 ); maxillary palp with three segments, segment 1 and 2 subequal in length, and much longer than segment 3; segment 3 triangular, ca 1.6× longer than wide at base; all setae on palp segments stout and entire ( Fig. 3E View FIGURE 3 ).

Hypopharynx with highly developed superlinguae terminated by a membranous digitation ( Fig. 3F View FIGURE 3 ).

Labium ( Fig. 3D View FIGURE 3 ) 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 1.2× longer than the maximum width, segments 2 as long as segment 3, ca 0.9× length of segment 1; segment 3 ca 1.8× longer than wide at base, conical shape, with 6–8 long and stout setae on dorsal face and inner margin with one row of longer and robust setae.

Thorax. Pro- and mesonotum medium brown, with greyish or brownish maculae, two light brown oval or rounded large maculae on the prothorax ( Fig 2A View FIGURE 2 ).

Legs light to medium brown; dorsal surface of femora and tarsi with greyish maculae.

Fore legs ( Fig. 4A View FIGURE 4 ) femora elongated, ca 2.4× longer than wide, dorsal surface covered with long, entire and pointed setae; fore tibiae subequal in length to femora, outer margin with few thin and long setae, inner margin with several rows of long stout and feathered setae; tarsi 0.5× 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 2.7× longer than wide, dorsal surface of femora with more numerous and slightly longer stout, pointed and feathered setae; tibiae and femora of subequal length; tarsi 0.5× length of tibiae.

Hind legs ( Fig. 4B View FIGURE 4 ) femora 3× longer than wide, dorsal surface covered with stout, pointed and feathered setae ( Fig. 4E View FIGURE 4 ); ventral surface with few stout setae; hind tibiae as long as hind femora, outer margin with very few long, stout, pointed setae; inner margin with stout, long, pointed, scattered setae; tarsi 0.4× length of tibiae, outer margin without or with 1–2 long and thin setae, inner margin with long, stout, pointed setae. Claws ( Fig. 4C View FIGURE 4 ) of all legs slightly hooked, with 11 to 12 denticles, the last four apically reduced in size ( Fig. 4D View FIGURE 4 ).

Abdomen. Tergites greyish to dark brown ( Fig. 2A View FIGURE 2 ). Tergites I–VIII with a dark brown band posteriorly tergites IX–X uniformly medium to light brown. Sternum I entirely greyish brown; sternites II−VIII greyish to lighter brown with posterior bands brown, and two parasagittal nervous ganglia dark brown; sternite IX greyish. Posterolateral expansions only on segments VIII and IX. Ornamentation of the tergites ( Figs. 5D–H View FIGURE 5 ): posterior margin of tergite IX with well-developed narrow and pointed spines, ca 2–3 times longer than wide, bordered with submarginal microdenticles; tergites VII−VIII with much narrower and shorter spines, bordered with submarginal microdenticles; tergites V−VI with needle-shaped spines, tergite III–IV with minute spines, not longer than the submarginal microdenticles; tergites I−II with barely visible spines.

Gills present on segments I−VII; all gills long and large; first gill ( Fig. 5A View FIGURE 5 ) with ventral lamella bearing 3–4 filaments, dorsal lamella with 3–4 filaments, gills II−VII ( Figs. 5B–C View FIGURE 5 ) with 3–4 and 4–7 filaments on the ventral and dorsal lamella respectively. Cerci and terminal filament yellowish brown, medium brown in mature nymphs ( Fig. 2A View FIGURE 2 ).

Eggs ornamented with small depressions surrounded by reticulated ribs shaped like a small-meshed net, distributed and arranged along the whole of the chorionic surface. These ribs are made up of microtubules joined together to form hexagonal, pentagonal or irregular rosette-shaped units ( Figs. 9A–B View FIGURE 9 ).

Imago. Unknown.

Etymology

This new species is named abietis to remember it inhabits a region where the endemic and endangered tree Abies marocana , the Moroccan fir or Rif fir, is still present.
