(Figs 1–4; 8A–J)  
 Diagnosis. As for genus. Body size: 282–332 × 232–265. Prodorsum rugose; notogaster and anogenital region areolate-reticulate; pteromorph foveolate or areolate-reticulate; epimeral region partially rugose, tuberculate and striate. Rostrum nasiform, rounded. Rostral, lamellar, interlamellar, notogastral, epimeral, and anogenital setae short, setiform, thin, roughened; le inserted on L or medial and very close to L. Bothridial seta clavate, slightly barbed. Dorsosejugal porose area and dorsosejugal suture present. Median pore absent. Circumpedal carina of medium length. Postanal porose area small and rounded. Solenidion on tibia IV inserted in the anterior part of the article.   
 Description of adult. Measurements. Body length: 298 (holotype: female), 282–332 (23 paratypes: six males and 17 females); notogaster width: 232 (holotype), 232–265 (23 paratypes). No difference between males in females in body size.   
 Integument. Body color dark brown. Body surface sparsely microfoveolate. Prodorsum rugose. Notogaster and anogenital region areolate-reticulate. Pteromorph usually foveolate (foveolae comparatively small; Fig. 3A, 3C); rarely (in two paratypes), areolate-reticulate (Fig. 3D). Lateral side of body with microgranulate cerotegument. Epimeral region partially rugose, tuberculate and striate. Subcapitular mentum, genital and anal plates striate. Antiaxial side of femora I-IV partially striate.   
 Prodorsum. Rostrum nasiform (visible in anterior view), narrowly rounded. Lamellar and sublamellar lines simple, parallel, curving ventrad. Rostral (18–20), lamellar (10–12) and interlamellar (8–10) setae setiform, thin, roughened; le inserted on L (Fig. 8A) or medial and very close to L (Fig. 4C). Bothridial seta (53–61) with long stalk and clavate (rounded apically), slightly barbed head. Dorsosejugal porose area oval (8–12 × 4), transversely oriented, located posterolaterally to insertion of interlamellar seta. Dorsophragma distinctly elongate longitudinally.   
 Notogaster. Dorsosejugal suture complete, convex medially, well visible. Posterior notogastral part with median longitudinal indistinct furrow. All notogastral setae (8–10) setiform, thin, roughened. Median pore absent in males and females. Opisthonotal gland opening and lyrifissures distinct: gla located close and laterally to h 3; im between lm and lp; ip between p 1 and p 2, closer to the former; ih and ips close to each other, anteriorly to p 3.   
 Gnathosoma. Size of subcapitulum: 82–90 × 69–73. Subcapitular setae (a: 18–20; m, h: 12–16) setiform, roughened; a thickest. Adoral seta (10–12) setiform, barbed. Length of chelicera: 90–98. Cheliceral setae (cha: 32–36; chb: 20–24) setiform, barbed. Length of palp: 69–73. Postpalpal seta (4) spiniform, smooth.   
 Epimeral and lateral podosomal regions. Epimeral setal formula: 1-0-1-1. Setae (3b: 12–14; 1a, 4a: 8–10) setiform, thin, roughened. Pedotectum II rounded in ventral aspect. Discidium triangular. Circumpedal carina of medium length, directed to insertion of 3b, but distinctly not reaching it.   
 Anogenital region. Genital (g 1: 12–14; others: 8–10), aggenital (8–10), anal (8–10), and adanal (8–10) setae setiform, thin, roughened. Anterior edge of genital plate with three setae. Aggenital seta located between genital and anal apertures, nearer to the former. Adanal setae ad 1, ad 2 posterior, ad 3 lateral to anal plate; distance ad 1 – ad 2 shorter than ad 2 – ad 3. Adanal lyrifissure located close and parallel to anal plate. Postanal porose area rounded (6–8).   
 Legs. Median claw thicker than lateral claws, all slightly barbed on dorsal side. Dorsoantiaxial porose area on femora I-IV and dorsoparaxial porose area on trochanters III, IV well visible; proximoventral porose area on tarsi I-IV and distoventral porose area on tibiae I-IV not observed. Formulas of leg setation and solenidia: I (1-4-3-4-20) [1-2-2], II (1-4-3-4-15) [1-1-2], III (1-2-1-3-15) [1-1-0], IV (1-2-2-3-12) [0-1-0]; homology of setae and solenidia indicated in Table 1. Famulus of tarsus I short, stickform, slightly swollen and blunt-ended apically, inserted anteriorly to solenidion ω 1. Seta s of tarsus I eupathidial, located before setae a. Solenidia ω 1 and ω 2 on tarsus II and σ on genu III bacilliform, other solenidia setiform, pointed or slightly rounded apically. Solenidion on tibia IV inserted in the anterior part of the article.   
 Note: Roman letters refer to normal setae, Greek letters to solenidia (except ɛ = famulus). Single quotation mark (’) marks setae on the anterior and double quotation mark (”) setae on the posterior side of a given leg segment. Parentheses refer to a pair of setae.   
 Type material. Holotype (female) and 23 paratypes (six males and 17 females): see locality in the Material and methods section. The holotype and two paratypes: SMNH; 21 paratypes: TSUMZ.   
 Etymology. The species name is dedicated to Prof. Dr. Wolfram Dunger, the German soil biologist and collembologist (9.X.1929 – 24.I.2019). Wolfram Dunger is considered as the founder of modern soil zoology in Germany; the long time he was the director of the SMNH in Görlitz.
