Figs. 20A–N , 21, 22, 25J,K, 27, 28, 29

Etymology. The species name refers to branched (Latin: ramosus) pouch lobes (Latin: sacculus) of the T7 gland.

Diagnosis. In the male sex very similar to Dz. (Dz.) altotuberculata , distinguished by the shorter, broadly rounded latero-posterior corners of T7, the huge opening of the T7 glandular pit and the ramose pouch lobes.

Material studied. Type material. MOROCCO. Holotype, 1♂, Moyen Atlas, btw. Merhraoua & Tizi-Oulmou, 1300 m, 28.V.1997, leg. B. & H.Bohn (completely on two slides, Ma 184/4). (Coll. Bohn, ZSM).

Additional material. Morocco. 2♂, Moyen Atlas, near M. F. Tamtroucht (S Tizi-Oulmou, S Taza), 1700 m, 27. V.1997, leg. B. & H.Bohn (slides: 2♂, Ma 13a/5,7) ; 1♂, 8♀, same data as holotype (slides: ♂, Ma 184/1; 5♀, Ma 184/3,5–8). (Coll. Bohn, ZSM) .

Description. Size. Length of pronotum in male 2.30–2.43 mm (mean 2.37 mm), in female 2.24–2.43 mm (mean 2.37 mm); N 4/7.

Male structures. ( Figs. 20A–M , 21, 22) Resembling Dz. (Dz.) planotuberculata and Dz. (Dz.) altotuberculata , more similar to the latter one. Median concavity of T6 similarly deep as in latter one, but much wider ( Figs. 20I–K ). Latero-posterior corners of T7 similarly produced as in the first mentioned species, but much broader; pre-glandular margin (pm) as long as in Dz. (Dz.) altotuberculata ; opening of glandular pit larger, occupying more than two thirds of the length of the tergite, elevations (el) of the posterior wall of the pit and of the bulge (bu) behind the pit similarly strongly sculptured as in Dz. (Dz.) altotuberculata . Pouch tubes with many short side branches, diameter of the main axis subbasally wider than elsewhere; interior cuticular lining with long, bristle-like microtrichial processes as in the preceding two species, inclined towards the exit ( Figs. 25J, K ). T10 with median part of posterior border shallowly but distinctly concave ( Fig. 20H ). Spatular bristles laterally on T5–7: densely arranged only on T7 ( Figs. 20E–G ), thinning out towards the latero-posterior corners. No glandular pores on T2.

Colouration. Tegmina. In both sexes transparent, without dark markers. Male. Similar to Dz. (Dz.) planotuberculata . 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; T2–6 anteriorly of the ridge dark, posteriorly on a relatively light ground colour with a dark maculose pattern producing at three positions more extended dark areas, T6 sometimes completely dark ( Figs. 20A–C, I–K ), T7 between bulge and the broadly dark lateral margin yellowish ( Figs. 20D , 21, 22); sternites mainly dark, lateral margins broadly yellowish. Female. Head dark, with yellowish post-interocular stripe; legs almost completely yellowish; discs of thoracic nota dark, sometimes with moderately extended lightenings, margins transparent ( Figs. 20M, N ); tergites anteriorly of ridge dark, posteriorly on a yellowish ground colour with a moderately extended dark maculose pattern; sternites mainly dark, with broadly yellowish lateral margins.

Distribution. Only known from two neighbouring localities in the massive Jebel Bou Iblane at the northern end of the Middle Atlas: One (Ma 184) between the distribution areas of Dz. (Dz.) planotuberculata and Dz. (Dz.) altotuberculata , at the other locality (Ma 13) they were found together with the first mentioned species, at elevations of 1300–1700 m ( Figs. 27 , 28 ).

FIGURE 27. Distribution of the species of subgenus Dziriblatta in Morocco and southern Spain (for mountains and locality numbers see Fig. 28). The lobososacculata-species group is distributed along the main mountain ranges of the Middle and High Atlas and the Rif, the bolivari-species group mainly further North: along the western Tell Atlas in Algeria (see fig. 32 in Bohn 2019), in northern Morocco including the northern part of the Middle Atlas, and in southern Spain along the Cordillera Penibetica, West of the Sierra Nevada up to Algeciras. The names of the species and their symbols are listed in the sequence of their distribution, which in the bolivari-species group is from East to West, in the lobososacculata-species group from North to South.The numbered arrows indicate localities with the common occurrence of two different species of subgenus Dziriblatta. In most cases Dz. (Dz.) algerica is found associated with another species, at locality 1 with Dz. (Dz.) bolivari, at 2 with Dz. (Dz.) ramososacculata, and at 4 with Dz. (Dz.) lobososacculata; at locality 3 Dz. (Dz.) ramososacculata is occurring together with Dz. (Dz.) planotuberculata.—Abbreviation: indet. females = indetermined females, only in Spain.
