Length 473–641 μm, width 395–509 μm (n = 38). Dorsal shield subcircular, smooth, with characteristic ornamentation of scattered circular pits in the posterior half. Marginal shield smooth, with numerous lyrifissures (id), fused with dorsal shield anteriorly. Dorsal setae numerous, simple (ca 24 µm long). Submarginal setae simple (ca 19 µm long), marginal setae numerous, very short, hook-like. Ve n t r a l idiosoma (Fig. 29). Endopodal shields, sternum and anterior part of opisthosoma ornamented with small pits. Sternal shield with 5 pairs of simple setae; st 1 located close to anterior edge of epigynium, st 2 –st 5 lateral to epigynium. Epigynium tongue-shaped (length 113–147 μm, width 75–95 μm), covered with numerous small oval pits. Opisthosoma smooth, except region behind epigynium covered with pits. Ventral setae (v 1 –v 5) simple, v 1 = ½ length v 2; setae v 4 –v 5 located on shield. Adanal setae Ad 1 very short, Ad 2 = 2 x Ad 1. Unpaired seta Pa = Ad 2. Anal opening small, oval. Peritremes V-shaped, length ca 87 μm. Tritosternum 6 - branched, with broad base, laciniae with finely serrated tips (Fig. 31). Gnathosoma. Epistome narrow, laterally serrated, anterior processes finely serrated. Hypostomal setae h 1 very long (ca 34 μm), simple; h 2 short (ca 12 μm), robust; h 3 short (ca 14 μm), blunt; h 4 short (ca 13 μm), curved, distally serrated (Fig. 30). Hypostomal surface covered with fine denticles of various sizes distributed irregularly between setae h 3 –h 4. Hypostomal groove smooth. Ventral setae pv 1 –pv 2 on palp trochanters robust, pv 1 ca 14 μm long, robust, blunt, pv 2 ca 10 μm long, simple. Chelicerae of average length, fixed digit with globular sensillus and small denticles on the internal surface, movable digit shorter than fixed digit, with single denticle on the internal surface. Legs. Structure and chaetotaxy typical for the genus (Fig. 32). Tarsi II–IV subdivided into basitarsus and telotarsus by complete peripodomeric fissure. Setae al and pl on tarsus II and III serrated, on tarsus IV only pl serrated. Male. Unknown. Deutonymph. Partly sclerotised, colour yellowish to light brown. Dorsal idiosoma (Fig. 33). Length ca 501 µm, width ca 426 µm. Dorsal shield subcircular, smooth, marginal shield absent. Dorsal setae numerous, simple; some accompanied by circular pores. Between the setae ca 6 pairs of dorsal lyrifissures (id). Submarginal setae simple, those in posterior part inserted on small tubercles. Marginal setae very numerous, short, hook-like. Ve n t r a l idiosoma (Fig. 34). Sternal shield amphora-shaped, with distinctly widened base, extending behind coxae IV, lightly ornamented medially. Sternal setae st 1 –st 5 very short.

One pair of lyrifissures (iv 3) located near setae v 2. Anal shield triangular, anal opening covered by a small valve and a pair of very short setae Ad 1. Setae Ad 2 and Pa on shield surrounding anus, Ad 2 = Pa. Peritreme long, with characteristic curve at level of coxae II, without poststigmatic extension, prestigmatic section (ca 141 μm long) reaching camerostome, stigmata at level of coxae III. Tritosternum typical for the genus. Gnathosoma. Epistome narrow and serrated, distally bifid. Hypostome similar to female, except setae h 2 simple and h 3 serrated (Fig. 35). Hypostomal denticles arranged in three rows between setae h 2 –h 4. Legs. Structure and chaetotaxy as for female. Ecology. This species is widely distributed in Europe, in low altitude habitats. It was described from Germany, and has subsequently been recorded from Albania, Czech Republic, France, Germany, Poland, Slovakia and Ukraine (Fig. 36), in the litter of oak-hornbeam forests and beechwoods. Wiśniewski & Hirschmann (1993) recorded this species in Lithuania, but this is a misidentification of specimens of Neodiscopoma as C. erlangensis. In Poland this species is never abundant (Fig. 67 C). It occurs in mixed deciduous forests, lowland and Carpathian beechwoods, fir-beech forests, marshy meadows, oak-hornbeam forests, fir forests, and parks. It is occasionally also found in grasses on non-limestone rocks, thickets of various types, grasses on limestone rocks and in rotten tree trunks. Its optimum altitude is below 400 m a.s.l.Published as part of Stachowiak, Marcin, Halliday, Bruce & Bloszyk, Jerzy, 2008, Review of the genus Cilliba von Heyden (Acari: Uropodina: Cillibidae), pp. 1-42 in Zootaxa 1881 on pages 15-19, DOI: 10.5281/zenodo.18419
