No full textNeolepidotrochus parvidiscus angolensis Bohn, 2005 (Figs 13 B–C, 14) Neolepidotrochus parvidiscus angolensis Bohn, 2005: 234 –237, figs 1 (C–G), 3, 4 Material. M 48 / 1340: Holotype (ZSM 20020017). Remarks. This subspecies has been recently described in more detail (Bohn 2005) and is characterised by: body wall and tentacle bases with two types of wheel deposits, neolepidotrochid type wheels (Fig. 13 B) and myriotrochid type wheels (Fig. 13 C). Neolepidotrochid type wheels with variable number (up to 16) of outwardpointing secondary teeth (Fig. 12 B: arrowheads), not present in all wheels, but in the majority; edge of rim between two outwardpointing primary teeth roughly straight; neolepidotrochid type wheels from anterior body smaller (mean diameter: 111, range: 95–129), than wheels from posterior body (mean diameter: 140, range: 127–158) and with higher ratio of hub diameter to wheel diameter (mean: 40 %, range: 30–47 %) compared to wheels from posterior body (mean: 29 %, range: 22–36 %). Myriotrochid type wheels have a diameter of 130 (75–166), ratio of hub diameter to wheel diameter 21 % (18–26 %), spokes 10 (8–14). Distribution.

(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.

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).Published as part of Bohn, Horst, 2021, Revision of the genus Dziriblatta Chopard, 1936 (Blattodea, Ectobiidae, Ectobiinae) III.

Luridiblatta graeca Bohn 2022, sp. nov.
No full text10. Luridiblatta graeca, sp. nov. Figs. 6D, 31A–L, 32A–G, 33H–J, 35F, 36D, 43 Diagnosis. From L. cyprica and L. beybienkoi distinguished mainly by two characters: the edge, a lateral continuation of the anterior border of the pit openening (ed in Fig. 33H–J), and the massive and more or less club-shaped glandular tubules (tu in Figs. 31D, 32C, 33I,J). Etymology. The species name refers to the hitherto known distribution of the species restricted to the country Greece (Crete and continental Greece). Material studied. Type material.

B. & H.Bohn (Kr 22); 9♂, 13♀, 3L, same data as holotype (slides: ♂, Kr 23/1; ♀, Kr 23/3–5). (Coll. Bohn, ZSMC). Description. Size. Male. Crete: Length of pronotum 1.86–2.05 (mean 1.95) mm, length of tegmina 4.54–5.44 (mean 4.94) mm. (N = 12/12). Female. Crete and Greece: Length of pronotum (mean) 1.98 mm, length of tegmina (mean) 2.37 mm. (N = 3/10). T6: Distance between the anterior bristle stripes as % of tergite breadth: range 14.6– 24.7, mean 19.8. (N = 9). Female tegmina. Apical border shallowly concave (Figs. 31H, 32B). Male abdomen. Tergites. Fig. 31A–F. T 6. Highly specialised as described under characters of the genus and the beybienkoi -group; in the main structures not differing from the other species of the group (Fig. 6D). Two alleged specialties visible in this figure, a membraneous transversal fold (fo) and a w-shaped dark line between the anterior bristle stripes (arrowhead) are occasionally also found in other species of the beybienkoi- group. The comparison with the other species (Figs. 1D, 6B,C) shows, however, that there are differences in the distance between the anterior bristle stripes; the distance is smallest in L. graeca (mean: 19.8% of the breadth of the tergite; L. beybienkoi 22.3%, L. quadrivittata 23.4 %, L. cyprica 25.7%). But since there is considerable overlap between the species (see corresponding values for each species under “ Size ”) these differences are of little value for species separation. T7. Pit. Anterior border (ab) of the pit opening laterally continuing into an narrow fold or edge (ed) converging with the gutter (gu) and approaching it closely near the lateral border of the tergite (Figs. 31D, 33H–J); pit size: up to size 5 (Fig. 31D); anterior pit wall (aw) with transparent windows (w), stabilising bracelet (s), window frame (wf), and transversal folds (tf, Fig. 32C–G); posterior pit wall (pw) with a pair of bulges (bu), either shallowly bowlshaped (Fig. 32F), or, more often, with a strange rectangular appearance (Fig. 33H–J). Glandular pouches (gp) long, tubules (tu), short, more or less club-shaped, rather massive, in nearly every preparation well visible (Figs. 31D, 33J). Genital hook. Claw (cl) as in L. cyprica with a large crest (cr) having two antlerlike processes (an, Fig. 31K,L). Distribution. Crete and Nom. Chalchidiki and Aetolia-Akarnia of continental Greece IV. Doubtful species The fourth group of species assembles two possible new species, which due to the incompleteness of the knowledge of their characters cannot yet be established as new species.Published as part of Bohn, Horst, 2022, Revision of the genus Luridiblatta (Blaberoidea, Ectobiidae, Ectobiinae), pp. 1-72 in Zootaxa 5215 (1) on pages 21-22, DOI: 10.11646/zootaxa.5215.1.1, http://zenodo.org/record/740338
Dziriblatta (Dziriblatta) undulata Bohn 2021, spec. nov.
No full text10. Dziriblatta (Dziriblatta) undulata, spec. nov. Figs. 23A–I, 24, 25A–I, 26E, G, 27, 28, 29 Etymology. The species name refers to the undulate shape of the posterior border of T6 having three concavities (unda, Latin word for wave). Diagnosis. In the male sex easily recognized by the strikingly whitish area posterior to the glandular pit of T7; further characterized by the well-produced latero-posterior corners of T5, the undulate shape of the posterior border of T6 with deep lateral concavities, the huge dome-shaped glandular pit of T7 without larger internal elevations, and the dense layers of spatular bristles on the lateral parts of T5-7.

Size. Length of pronotum in male 1.95–2.18 mm (mean 2.06 mm), in female 2.19–2.40 mm (mean 2.25 mm); N 8/8. Male structures. Latero-posterior corners of T2–4 weakly produced, those of T5, 6 rather strongly produced; posterior border of T2–5 weakly convex or straight, of T6 undulate, with three concavities; in contrast to the other species of the lobososacculata -species group lateral concavities much deeper than median one, intermediate parts strongly convex, transversal ridge with a mesal excurvation to the anterior (Figs. 23A–C, F, G); in T5,6 length of preglandular margin (pm) distinctly increasing towards the median notch (Fig. 23B,C); surfaces of T3–6 mesally deepened to a common shallow sagittal trough, deepest and broadest on T6, fading away in both dimensions up to T3 (the trough not visible in the figures). T7 (Figs. 23D, H, I, 24) with a deeply concave posterior border, producing broadly rounded triangular latero-posterior corners; surface of the tergite appearing tripartite by areas with whitish cuticle encircling the opening of the glandular pit; consisting of two narrow, towards posteriorly converging areas with longitudinal folds (upper arrows in Fig. 24), each starting in a membraneous area at the latero-anterior corners of the tergite and posteriorly merging into a broader whitish area with wrinkled surface extending between the posterior borders of pit opening and tergite (between lower arrows of Fig. 24). Opening of the glandular pit large, broadly transversely oval, occupying more than half of the breadth and about two thirds of the length of the tergite (between ab and pb). Pit rather deep, dome-shaped, with steeply descending walls; bottom small, bowl-shaped, adjacent on the anterior wall with a membraneous window (w) containing the openings of the two pouch lobes. Posterior wall with a low, narrow, partly unsclerotized sagittal ridge (pr) reaching down to the bottom and up to the posterior border of the tergite. Pouch lobes (Fig. 24) narrowly cylindrical, of more than abdominal length, wriggled, opening into the pit near together but separately within the membraneous window; interiorly near the opening with numerous bristles reaching with their ends into the pit hole; cuticular lining of the lobes with bristle-like microtrichial structures, shorter than in the preceding three species and radially aligned (Figs. 25H, I). T10 with median part of posterior border shallowly, but distinctly concave (Figs. 23E). Spatular bristles laterally on T5–7: densely arranged in all three tergites (Figs. 25E–G). No glandular pores on T2. Colouration. Very similar to Dz. (Dz.) lobososacculata. Tegmina (Figs. 25A–D) transparent; in the male along the anterior margin infuscated, along the posterior margin with variously sized patches, at the base partly uniting to a larger patch; female tegmina only basally at the posterior margin slightly infuscated, but disc often with several dark spots of various size. Male. Mainly brown to dark brown. Head dark, with yellowish post-interocular stripe; discs of thoracic nota uniformly dark, margins transparent (Fig. 25C); legs mostly dark except for the lighter coloured coxatrochanter and femur-tibia joints, rarely with more extended yellowish areas; tergites mainly dark, but often variably lightened, especially laterally on T2–4, with a maculose appearence (Fig. 23A); lightenings in the specimens from the most eastern locality (Ma 225, Fig. 23G) more extensive than in those from the more western localities; T7 medially posteriorly to the pit opening strikingly whitish (Figs. 23D, H, I, 24); sternites almost completely dark, only lateral margins slightly lightened. Female. Head mainly dark, with yellowish post-interocular stripe; discs of thoracic nota dark, at most with very slight lightenings, margins transparent (Fig. 25D); legs almost completely yellowish; tergites on a yellowish ground colour extended maculose; sternites mainly dark, laterally with a relatively broad yellowish margin. Distribution. Distributed in the Rif mountains between Chefchaouen in the West and Aknoul (about longitude of Al Hoceima) in the East, at elevations of 1500–1800 m (Figs. 27, 28). It was not possible to exactly identify the localities Bab Ruadi and Hauta Kasdir; both should be situated in the region Beni Esjjel [in older literature called Beni Sayel, B. Seyel, or B. Siyyel] in the NE of Chefchaouen [= El Aaiún]. The position of the corresponding locality [Ma 19] in the distribution map, therefore, only indicates the approximate position. Remarks. The distribution of this species partially overlaps with the distribution of Phyllodromica vignai Failla & Messina, 1989; both species, which are very similarly coloured, were found together at locality Ma 6 (Bohn 1993). While the males of the two species can easily be distinguished solely by external inspection (Ph. vignai has longer tegmina considerably surpassing the posterior border of the mesonotum), a reliable distinction of the females requires the study of the genital sclerites: dorsal basivalvular sclerites (bd) of both sides in Ph. vignai separate (Fig. 26F), in Dz. (Dz.) undulata (as in most of the subgenera of the genus Dziriblatta) fused to an ringlike structure (Fig. 26E); laterosternal shelf (ls) in Ph. vignai fairly rounded with long lateral arms (a) (Fig. 26H), in Dz. (Dz.) undulata (as in most subgenera of Dziriblatta) transversal with very short arms (Fig. 26G).Published as part of Bohn, Horst, 2021, Revision of the genus Dziriblatta Chopard, 1936 (Blattodea, Ectobiidae, Ectobiinae) III.

Dziriblatta (Dziriblatta) planotuberculata Bohn 2021, spec. nov.
No full text7. Dziriblatta (Dziriblatta) planotuberculata, spec. nov. Figs. 14A–N, 15, 16, 27, 28, 29 Diagnosis. In the male distinguished from Dz. (Dz.) lobososacculata by the very different structures of pit and pouch lobes and the length of the pre-glandular area of T5,6 strongly increasing towards the median notch (n in Fig. 14I); from Dz. (Dz.) undulata by the differences in the shape of T6, and from Dz. (Dz.) altotuberculata and Dz. (Dz.) ramososacculata by the lower elevations on the posterior wall of the pit and the differently shaped latero-posterior corners of T7. Etymology. The species name refers to the relatively flat (in Latin: planus) mound (in Latin: tuber) on the posterior wall of the glandular pit. Material studied. Type material. MOROCCO. Holotype, 1♂, Moyen Atlas, near M. F. Tamtroucht (S Tizi-Oulmou, S Taza), 1700 m, 27.V.1997, leg. B. & H.Bohn (completely on two slides: Ma 13a/6). (Coll. Bohn, ZSM). Additional material.

Length of pronotum in male 2.05–2.35 mm (mean 2.21 mm), in female 2.40 mm (mean 2.40 mm); N 8/2. Male structures. Posterior borders of T2–5 (Figs. 14A, B) fairly straight or slightly concave; posterior border of T6 with a slightly deeper median excavation than in the preceding species, transversal ridge with a broad mesal excurvation to the anterior (Figs. 14I–K), length of pre-ridge area towards the median notch rather strongly increasing; surface of T6 mesally with a similar trough as in Dz. (Dz.) lobososacculata, but posteriorly more or less closed by a slight bending up of the posterior border of the tergite. Latero-posterior corners of T7 moderately produced to broadly rounded lobes, posterior border of the tergite in between deeply concave; pre-glandular margin of normal length (Figs. 15, 16), not as far protruding anteriorly as in the following two species. Opening of the glandular pit posteriorly not well demarcated, occupying more than half of the length and more than a third of the breadth of T7 (Figs. 14D, 15, 16; pb in Fig. 15 indicates the approximate position of the posterior border of the opening); walls of the pit almost uprightly descending, forming a rather deep bag-like pit. Posterior wall with a relatively low elevation (ce central elevation) increasing in height up to the middle depth of the pit; cross-section of the pit hole, therefore, from the oval at the opening changing to a crescent shape in the lower half of the pit. Elevation of the posterior wall restricted to the mesal two thirds of its breadth and laterally lowered towards the gutters (gu), which smoothly continue downward into the trails (tl). Anterior wall of pit mesally near the bottom with a membraneous window (w) containing the openings of the two pouch lobes; posteriorly adjacent, at the bottom between the trails the beginning of a long, relatively low ridge (pr posterior ridge) reaching up to the pit opening where it continues into a bulge (bu) ending at the posterior border of the tergite; bulge fairly wedge-shaped, posteriorly narrow and usually well set off, broadening anteriorly and fading away near the posterior border of the pit opening (pb). Pouch lobes narrowly cylindrical, tubelike, of more than abdominal length, wriggled in about half of the specimens with few very short side branches (Fig. 16), interiorly with numerous bristle-like microtrichial structures, longer than the diameter of the tubes and, therefore, inclined towards the exit (as in Figs. 25J, K); near the entry into the pit with numerous long bristles reaching with their tips into the pit hole; tubes separately, but close together opening into the pit, within the above-mentioned window. T10 with median part of posterior border shallowly but distinctly concave (Fig. 14H). Spatular bristles laterally on T5–7, densely arranged only on T7 (Figs. 14E–G). No glandular pores on T2. Colouration. Tegmina in both sexes transparent (Figs. 14L–N), at most with few small darker dots. Male. 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 (Fig. 13L); T2-6 anteriorly of the ridge dark, posteriorly on a yellowish ground colour with a dark maculose pattern producing at three positions more extended dark areas (Figs. 14A–C, I–K), in T7 a large median area posteriorly of the pit opening yellowish (Figs. 14D, 15, 16); sternites mainly dark, lateral margins broadly yellowish. Female. Head dark, with yellowish post-interocular stripe; legs almost completely yellowish; discs of thoracic nota usually dark, not seldom with extended lightenings (Figs. 14M, N); tergites anteriorly of the ridge dark, posteriorly on a yellowish ground colour with a modestly extended dark maculose pattern; sternites mainly dark, lateral margins broadly yellowish. Distribution. The species continues the distribution of the preceding species along the Middle Atlas North of the River Sebou, covering the southern part of the massive Jebel Bou Iblane, at elevations of 1500–2000 m (Figs. 27, 28).Published as part of Bohn, Horst, 2021, Revision of the genus Dziriblatta Chopard, 1936 (Blattodea, Ectobiidae, Ectobiinae) III.

No full text4. Dziriblatta (Dziriblatta) pilleata, spec. nov. Figs. 2J, 3I, 7A–I, 27, 28, 29 Etymology. The species name refers to the caplike (pilleus in Latin) shape of the pouch lobes. Diagnosis. Distinguished from the preceding three species by the differently shaped tergites T6,7 and extremely short and apically more or less transversely cut pouch lobes. Material studied. Type material. SPAIN. Holotype, 1♂, ex L, Prov. Cádiz, Nuevo Castellar (ca. 20 km N Algeciras), ca. 100 m, leg. B. & H.Bohn, 27./ 28.III.1988 (completely on two slides: Sp 187/13). (MNMS). Additional material. SPAIN. Same data as holotype: 1♀; same locality as holotype: 5♀, 1. V.1997 (Sp 187a). (Coll. Bohn, ZSM). Description. Size. Length of pronotum in the male 2.18 mm, relative length of pouch lobes 37% (Table 2). Male structures. (Figs. 7A–I). Posterior borders of T4,5 slightly concave, T6 with a very deep sinusoidal excavation, posterior border of T7 also deeply concave, latero-posterior corners narrowly triangular, latero-anterior shoulders not developed, broadly rounded (arrow in Fig. 7D); bottom of trail sievelike due to numerous glandular pores (Fig. 7H); lateral gutters and holes distinctly curved posteriad; pouch lobes very short, caplike, with almost transversely cut tip (Fig. 7D, E); bristles similarly as in the preceding species with long bristles loosely distributed over the full width of the pit opening, but all strongly and unregularly curled (Fig. 7F, G). Glandular pores laterally on T2: present, but in low numbers along the anterior border of the tergite (Fig. 2J). Distribution. Spain, Andalusia: One locality near Algeciras at an elevation of 100 m (Figs. 27, 28). Remarks. The singular male specimen available shows strong differences to all other species of the subgroup in the shapes of T6 and T7 and in the shape and length of the pouch lobes. The differences are strong enough to consider it as a different species. However, the specimen was grown from a juvenile; it cannot be excluded that the development of the structures is modified by the unnatural conditions of the life in captivity. The reason for the doubt is, that the margins and surfaces of T6 and T7 show slight but unusual undulations, which could be interpreted as signs for an incomplete stretching of the cuticle after moulting. However, numerous specimens of the two preceding species had also been reared from larvae (as the specimens from Fig. 5D, E) but did not show any abnormalities apart from a possibly lighter colouration. Since in the decisive structures of pouch and pits no signs of an abnormal development can be seen it appears justified to consider the specimens from locality Ma 186 as representatives of a new species.Published as part of Bohn, Horst, 2021, Revision of the genus Dziriblatta Chopard, 1936 (Blattodea, Ectobiidae, Ectobiinae) III.

Benadalid & Atajate (ca. 20 km SW Ronda), 750 m, 23.III.2000, leg. T. Knebelsberger (slide: ♂, Sp 488/1). (Coll. Bohn, ZSM). Description. Size. Length of pronotum in holotype 2.18 mm, relative length of pouch lobes of T7 gland 58– 75% (mean 69.8%) (N22, Table 2). Male structures. T7 gland similar to the preceding species, but pouch lobes much shorter; shape of pouch lobes very variable, mostly obtusely conical, with broadly rounded tip (Figs. 3E, F, 4D, 5A–C), rarely with a more narrowly rounded tip (Fig. 3D); long pit bristles not as strictly straight as in Dz. (Dz.) bolivari, at least tips slightly curved, and their bundles less dense, short pit bristles often rather strongly curled (Figs. 4F–H); lateral pit holes usually more deeply hollowed out, shape very variable, circular or more elongated, in the latter case often curved towards posteriorly (Figs. 5A–C). Glandular pores laterally on T2: present, but of variable number, mostly well developed (Fig. 2I) as in the preceding species, but partly as sparce as in the following two species (Figs. 2H, J). Distribution. Spain, Andalusia, western part of the Cordillera Penibetica. One locality north of Malaga, other localities further west in the mountain ranges Serranía de Ronda and Sierra Bermeja, at elevations of 600–1400 m (Figs. 27, 28). Remarks. Three of the 23 male specimens studied had pouch lobes with less broadly rounded tips, thus resembling Dz. (Dz.) bolivari in this respect and raising the question about how well the two species can be separated. However, all three specimens have very short pouch lobes (Sp 193a/4, Fig. 3D: 69%, Sp 457/1: 67%, Sp 457/6: 58%) with length values below the mean value (69.8%) of the specimens studied, confirming their affiliation to the new species. The use of the lobe length as a decisive criterion for the distinction of the two species appears justified since their ranges in this parameter, though rather near together, do not overlap. The rather strong differences in the colouration of the males also supports this assumption (see below). There remains the need to treat one obviously aberrant specimen of the species (Sp 193a/1, Fig. 5A). It has an extremely long right pouch lobe (100%) with broadly rounded tip, its left lobe is slightly shorter and shows a kind of asymmetrical branching. The branching is interpreted to be the result of a severe developmental disturbance, which could also have influenced the development of the right lobe. The excessive length of the right lobe is, therefore, considered as an artifact and not included in the calculations concerning the length of the pouch lobes.Published as part of Bohn, Horst, 2021, Revision of the genus Dziriblatta Chopard, 1936 (Blattodea, Ectobiidae, Ectobiinae) III.
