T6 unusually long, length/breadth ≥39% ( Figs. 2C–F ); T5–7 laterally with sparsely distributed spatular bristles ( Figs. 1B–D ); pouch lobes of T7 gland at least basally sclerotized, shortly before opening into the pit united to a large common orifice almost of the breadth of the pit ( ep , Figs. 1A , 8 ); transversal mesal part of the posterior border of T10 between weakly convex to weakly concave ( Figs. 1E, F , 3G–I )....................................................................... 2 - T6 not unusually long, length/breadth ≤36% ( Figs. 10F–H ); at least T7 laterally with densely arranged spatular bristles ( Figs. 12D, E ); pouch lobes of T7 gland unsclerotized, each separately opening with a relatively small orifice into the pit ( Fig. 11C ); transversal part of the posterior border of T10 distinctly concave ( Fig. 10E )....................................... 6 2. Pouch lobes much longer than the length of T7, only in the basal part and there only weakly sclerotized, throughout their length flat; only with a large bipartite pit ( Fig. 8 ); discs of thoracic nota usually completely dark......... Dziriblatta ( Dz .) algerica - Pouch lobes not or only scarcely longer than the length of T7, conical, in full length three-dimensional and sclerotized; apart from the large bipartite pit additionally on each side with a smaller circular pit (hole) ( Fig. 1A ); discs of thoracic nota never completely dark, either almost completely lightly coloured or dark maculose...................................... 3 3. Pouch lobes of about the length of T7 (87–126%, mean 102%), conical, with narrowly rounded tip ( Figs. 1A , 3C ); long pit bristles strictly straight, forming on each side a slender and dense bundle ( Figs. 3A, B )........... Dziriblatta ( Dz. ) bolivari - Pouch lobes shorter, measuring less than 84% (mean 70% or less) of the length of T7, tip usually broadly rounded; long pit bristles less straight, forming usually less dense bundles....................................................... 4 4. Posterior border of T6 with a deep sinusoidal excavation ( Fig. 7C ), T7 with strongly produced latero-posterior corners and a wide concavity in between ( Fig 7D ); pouch lobes very short, caplike, with more or less transversely cut tip, length 37% ( Fig. 7E ); all pit bristles strongly curved or curled ( Figs. 7F, G )......................... Dziriblatta ( Dz. ) pilleata spec. nov. - T6,7 similarly shaped as in the other members of the species group: posterior border of T6 only with a week excavation ( Fig. 4C ), latero-posterior corners of T7 moderately produced ( Fig. 4D ); pouch lobes longer, obtusely conical, with broadly rounded tip ( Fig. 3D ), at least long pit bristles less strongly bent....................................................... 5 5. Length of the pouch lobes 58-83b% (mean 70%) ( Figs. 3D–F , 4D , 5A–C); long pit bristles almost straight, only tips may be slightly bent, arranged in rather compact bundles ( Figs. 4F–H )..................... Dz. ( Dz .) brevisacculata spec. nov. - Length of pouch lobes 45-59% (mean 53%) ( Figs. 5D–F , 6D ), long pit bristles more strongly bent, loosely distributed over the full width of the pit hole ( Fig. 6F–H )....................................... Dziriblatta ( Dz .) curvisetosa spec. nov. 6. Pouch lobes very flat, elongated lappet-shaped, basally broad, about as broad as half of the glandular pit of T7, apically pointed, often unregulartly lobated and folded ( Figs. 12A , 13 )............................. Dz. ( Dz. ) lobososacculata spec. nov. - Pouch lobes narrowly cylindrical, tubelike, longer than the abdomen, wriggled ( Fig. 15 )............................. 7 7. Latero-posterior corners of T5 triangularly produced ( Fig. 23B ); T5‒7 laterally densely covered with spatular bristles ( Figs. 25E–G ); posterior wall of the pit apart from a low and narrow sagittal ridge without elevations ( Fig. 24 ); surface posteriorly of the pit opening more or less membraneous and rather conspicuous by its whitish appearance... Dz . ( Dz .) undulata spec. nov. - Latero-posterior corners of T5 not produced ( Figs. 10B , 14B ); only T7 laterally densely covered with spatular bristles ( Figs. 14E–G ); posterior wall of the pit with an elevation covering a large part of its breadth ( Figs. 15 , 18 , 22 ); surface posteriorly of the pit opening not membraneous......................................................................... 8 8. Pre-glandular margin of T7 only slightly produced anteriorly; elevations on the posterior wall of the glandular pit relatively flat ( Figs. 15 , 16 )............................................................ Dz . ( Dz .) planotuberculata spec. nov. - Pre-glandular margin of T7 strongly produced anteriorly; elevations on the posterior wall of the glandular pit higher ( Figs. 18 , 22 )................................................................................................. 9 9. Pouch lobes with numerous short side branches; latero-posterior corners of T7 scarcely produced, broadly rounded ( Fig. 22 )...................................................................... Dz . ( Dz .) ramososacculata spec. nov. - Pouch lobes unbranched or with only few, very short side branches; latero-posterior corners of T7 strongly produced, narrowly rounded ( Fig. 18 )......................................................... Dz . ( Dz .) altotuberculata spec. nov.
