Figs. 14A–N, 15, 16, 27, 28, 29
Diagnosis. In the male distinguished from Dz. (Dz.) lobososacculata by the very different structures of pit and pouch lobes and the length of the pre-glandular area of T5,6 strongly increasing towards the median notch (n in Fig. 14I); from Dz. (Dz.) undulata by the differences in the shape of T6, and from Dz. (Dz.) altotuberculata and Dz. (Dz.) ramososacculata by the lower elevations on the posterior wall of the pit and the differently shaped latero-posterior corners of T7.
Etymology. The species name refers to the relatively flat (in Latin: planus) mound (in Latin: tuber) on the posterior wall of the glandular pit.
Material studied. Type material. MOROCCO. Holotype, 1♂, Moyen Atlas, near M. F. Tamtroucht (S Tizi-Oulmou, S Taza), 1700 m, 27.V.1997, leg. B. & H.Bohn (completely on two slides: Ma 13a/6). (Coll. Bohn, ZSM).

Description. Size. Length of pronotum in male 2.05–2.35 mm (mean 2.21 mm), in female 2.40 mm (mean 2.40 mm); N 8/2.
Male structures. Posterior borders of T2–5 (Figs. 14A, B) fairly straight or slightly concave; posterior border of T6 with a slightly deeper median excavation than in the preceding species, transversal ridge with a broad mesal excurvation to the anterior (Figs. 14I–K), length of pre-ridge area towards the median notch rather strongly increasing; surface of T6 mesally with a similar trough as in Dz. (Dz.) lobososacculata, but posteriorly more or less closed by a slight bending up of the posterior border of the tergite. Latero-posterior corners of T7 moderately produced to broadly rounded lobes, posterior border of the tergite in between deeply concave; pre-glandular margin of normal length (Figs. 15, 16), not as far protruding anteriorly as in the following two species. Opening of the glandular pit posteriorly not well demarcated, occupying more than half of the length and more than a third of the breadth of T7 (Figs. 14D, 15, 16; pb in Fig. 15 indicates the approximate position of the posterior border of the opening); walls of the pit almost uprightly descending, forming a rather deep bag-like pit. Posterior wall with a relatively low elevation (ce central elevation) increasing in height up to the middle depth of the pit; cross-section of the pit hole, therefore, from the oval at the opening changing to a crescent shape in the lower half of the pit. Elevation of the posterior wall restricted to the mesal two thirds of its breadth and laterally lowered towards the gutters (gu), which smoothly continue downward into the trails (tl). Anterior wall of pit mesally near the bottom with a membraneous window (w) containing the openings of the two pouch lobes; posteriorly adjacent, at the bottom between the trails the beginning of a long, relatively low ridge (pr posterior ridge) reaching up to the pit opening where it continues into a bulge (bu) ending at the posterior border of the tergite; bulge fairly wedge-shaped, posteriorly narrow and usually well set off, broadening anteriorly and fading away near the posterior border of the pit opening (pb). Pouch lobes narrowly cylindrical, tubelike, of more than abdominal length, wriggled in about half of the specimens with few very short side branches (Fig. 16), interiorly with numerous bristle-like microtrichial structures, longer than the diameter of the tubes and, therefore, inclined towards the exit (as in Figs. 25J, K); near the entry into the pit with numerous long bristles reaching with their tips into the pit hole; tubes separately, but close together opening into the pit, within the above-mentioned window. T10 with median part of posterior border shallowly but distinctly concave (Fig. 14H). Spatular bristles laterally on T5–7, densely arranged only on T7 (Figs. 14E–G). No glandular pores on T2.
Colouration. Tegmina in both sexes transparent (Figs. 14L–N), at most with few small darker dots. Male. Head dark, with yellowish post-interocular stripe; forelegs for most part dark, mid- and hindlegs with extended yellowish parts; discs of thoracic nota dark, margins transparent (Fig. 13L); T2-6 anteriorly of the ridge dark, posteriorly on a yellowish ground colour with a dark maculose pattern producing at three positions more extended dark areas (Figs. 14A–C, I–K), in T7 a large median area posteriorly of the pit opening yellowish (Figs. 14D, 15, 16); sternites mainly dark, lateral margins broadly yellowish. Female. Head dark, with yellowish post-interocular stripe; legs almost completely yellowish; discs of thoracic nota usually dark, not seldom with extended lightenings (Figs. 14M, N); tergites anteriorly of the ridge dark, posteriorly on a yellowish ground colour with a modestly extended dark maculose pattern; sternites mainly dark, lateral margins broadly yellowish.
Distribution. The species continues the distribution of the preceding species along the Middle Atlas North of the River Sebou, covering the southern part of the massive Jebel Bou Iblane, at elevations of 1500–2000 m (Figs. 27, 28).
