Figs. 1A, F , 2A–C, F, G , 3A–C , 27 , 28 , 29

For distribution references and characters not treated here see Bohn 2019: 27, figs. 16A‒I, 29.

Description. Size. Length of pouch lobes more or less same length as T7 (87‒126%, mean 102%, Table 2 ); longer than in Moroccan specimens than in those from Spain (111% versus 93%).

Male structures ( Figs. 1A , 3A–C ): Pouch (p) of the T7 gland with two long lobes united at the base forming a short but wide common end piece (ep) opening into the posteriorly adjacent glandular pit. In cross-section the end piece more or less transversely oval, but the lobes soon after their separation with walls widening to an almost circular circumference, conical with narrowly rounded tip, fully sclerotized. Dorsal wall of the pouch ending posteriorly on the sharp edge of its opening (po) describing an arc in dorso-anterior direction; ventrally no visible limitation, the ventral wall of the pouch passing subtly over into the bottom of the pit. Pit anteriorly limited by the pouch opening, posteriorly by the almost upright posterior wall of the pit (pw); its transversal course medially interrupted by a process arising from the posterior wall towards anteriorly and forming a kind of septum (sagittal ridge, r) dividing the posterior part of the pit hole. The bottom of the pit anteriorly unsclerotized, membraneous (m), sclerotized posterior part on both sides of the sagittal septum deepened to a transversely oval trail (tl) which laterally, beyond the opening of the pouch, continues into a broad gutter (gu) ascending to the tergite surface and ending there in a shallow circular deepening, the lateral hole (h). The ventral wall of the pouch lobes covered by many long bristles, those near the opening forming a dense bundle reaching into the pit as far as the anterior end of the sagittal ridge (long pit bristles, lbr). The bristle epithelium continuing outside the pouch in two converging toward mesally narrowing ribbons ( Fig. 3A ); bristles shorter (short pit bristles, sbr) and steadily decreasing in length mesad; thus, all bristles outside the lobes with ends in about the same region near the sagittal ridge. Glandular pores laterally on T2, numerous, covering an area of about half of the length of the pre-ridge area ( Fig. 2G ).

Distribution. Northern Morocco between Cabo Espartel and Melilla peninsula; in Spain, Andalusia, Cordillera Penibetica, only at one locality in the Sa. del Chaparral, at an elevation of 1000 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.

FIGURE 29. Cladogram of the species of subgenus Dziriblatta reconstructed via the states of 9 male characters as listed below. Due to the complexity of the structures the “characters” are mostly character complexes rather than single characters. The presumed character states of the last common ancestor are listed at the root of the cladogram.—The alphabetic sequence of the states usually follows the assumed sequence in the evolution. But after a branching two different evolutionary lines may develop; the branching point is marked by an arrow (k) indicating where the line branching off is continued. The end of a line is marked by a slash.—For the species of the bolivari subgroup a separate character (10) was introduced in order to allow a differentiation between the four very similar species.
