description: Key for the determination of the males of subgenus Dziriblatta
1. 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.
