Size. Length of pronotum in male 1.86–2.11 mm (mean 1.95 mm), in female 2.14–2.46 mm (mean 2.23 mm); N 10/9. Male s tructures. Posterior border of T2–5 slightly concave ( Fig. 10A, B ), of T6 with a wide, moderately deep median excavation, lateral parts either slightly convex, or fairly straight, or towards the latero-posterior corner with a wide and very shallow concavity, border in the latter case, therefore, appearing weakly undulate ( Figs. 10F–H ); length of pre-ridge area slightly increasing towards the median notch ( n in Fig. 10H ); surface of the tergite in the mesal third towards the posterior border deepened to a shallow trough , not visible on the figures. T7 with moderately concave posterior border ( Figs. 10D , 12A, 13), lateral borders well rounded. At first view the gland structures of Dz. ( Dz. ) lobososacculata appear to be very similar to those of Dz. ( Dz. ) algerica , with a bipartite pit and long flat pouch lobes; but a more thorough inspection reveals a quite dramatic rebuilding in both structures ( Figs. 11A–C ). The pit is deeper than in the preceding species group. Its opening forming a large transversal oval, anteriorly well defined by the pre-glandular margin ( pm ) from which the slightly curved anterior wall ( aw ) steeply descends to the bottom of the pit, consisting of two neighbouring, sclerotized, transversely oval and posteriorly slightly diverging parts, certainly homologous to the bottom of the trails ( tl ). Laterally and posteriorly, where the walls have a less steep inclination, the opening much less well demarcated; in Fig. 12A the white line indicates the approximate position of the posterior border ( pb ). The posterior arc of the pit wall modelled by two interfacing structures: the steeply ascending gutters ( gu ) arising laterally from the trails, diverging as the trails, and the posterior, triangular surface in between forming a plane, less steeply descending than the gutter, but still with a rather steep inclination. The very sharp dark diagonal contours on the posterior wall visible in the figures ( arrow in Fig. 11B ) represent the points of transition between the two structures pretending distinct edges as are found in the preceding species group; but there are no sharp edges, the transitions from one to the other structure occur rather smoothly. The artefact is caused by the angle of view being almost parallel to the descending plane, a view, by which even very low depressions or elevations might appear as a dark contour. The descending posterior wall bears medially a longitudinal ridge, the posterior ridge ( pr) , laterally accompanied by a pair of parallel grooves ( gr) ; the ridge ends at the bottom of the pit in a short and low nose ( n , Fig. 11B ) thus, a kind of a bipartition is only found at the bottom of the pit. The structure of the pouch strongly differs from that of the preceding species group by the absence of a common end piece; the two lobes open separately and at a different site of the pit. The lobes ( Figs. 12A , 13 ) are completely unsclerotized, long and lappet shaped, from a broad base gradually tapering to a narrow tip, with irregularly shaped lateral borders, usually densely folded, and in stretched state certainly of more than abdominal length. Both lobes at the broad base suddenly narrowed to a short tail pipe ( tp , Fig. 11C , between arrows), both opening separately but near each other into the pit ( po ), within an unsclerotized area ( w window) of its anterior wall ( aw ). Interior of the lobe with some long bristles only near the tail pipe ( lbr , Fig. 12A ), interior of the tail-pipe and a short ribbon posteriorly of the opening densely covered with relatively short bristles ( sbr ); internal cuticular lining of the lobes with tiny comblike processes ( Fig. 26A ). T10 with median part of posterior border shallowly, but distinctly concave ( Fig. 10E ). Spatular bristles laterally on T5–7: densely arranged only on T7 ( Figs. 12D, E ), but—in contrast to the other species of the group — relatively numerous also on T6 ( Fig. 12C ). Glandular pores on T2: laterally absent, but sometimes very few around the median notch. Colouration. Very similar to Dz. ( Dz .) undulata . Tegmina transparent, with some dark spots, anterior border only in the male sometimes slightly infuscated, posterior border usually rather strongly infuscated, in the male more than in the female ( Figs. 10I, J ). Male. Head dark, with yellowish post-interocular stripe; discs of nota uniformly dark, margins transparent ( Fig. 10K ); legs apart from the lighter coloured coxa-trochanter and femur-tibia joint usually completely dark, but not seldom also with larger lightened areas; tergites on a rather dark ground colour densely covered with medium sized dark patches, on T2–5 usually well visible, in the more posterior tergites blending to a more or less uniformly dark colour; ground colour in T2–5 laterally strongly lightened, T6,7 laterally only with a narrow and weak lightening, T8–10 without lightenings ( Figs. 10A–H ). Female. Head as in male; legs almost completely yellowish; discs of nota very variable in colour, from almost completely dark to mainly yellowish with dispersed dark patches, margins transparent ( Figs. 10L–N ); abdominal tergites with the usual female pattern, variously maculose on a straw-coloured ground. Remarks. The species has a very wide distribution following the mountain chains of the High and Middle Atlas from South of Marrakech up to East of Meknes and Sefrou. The wide distribution corresponds with an unusually high variability in numerous characters: (1) shape of the posterior border of T6 ( Figs. 10F–H ); (2) length and shape of the pouch lobes ( Figs. 12A , 13 ); (3) shape and steepness of the lateral gutters of the pit ( Figs. 11A–D ); (4) strength of the posterior ridge and adjacent grooves on the posterior wall of the pit ( Figs. 11A–D ). Some of the variations show a kind of a South-North gradient: the simplest shape of T6 ( Fig. 10F ) and the lowest ridge on the posterior wall of the pit ( Figs. 11A ) are found in the most southern parts of the distribution area. Despite the rather strong differences it was not possible to further divide the heterogeneous assemblage into separate units. Distribution. Southern High Atlas from near J. Toubkal (about longitude of Marrakech) northwards to J. Ayachi (Midelt), then following the Middle Atlas for most of its length up to the river Sebou (latitude of Sefrou), at elevations of 900–2200 m ( Figs. 27 , 28 ).
