Uropoda (Cilliba) stammeri Hirschmann & Zirngiebl-Nicol, 1964: 19, Fig. 16; Hirschmann & Zirngiebl-Nicol, 1965: 4; Hirschmann & Zirngiebl-Nicol, 1969a: 27; Hirschmann, 1979a: 21; Wiśniewski, 1993a: 270; 1993b: 421; Wiśniewski & Hirschmann, 1993: 193.
Material examined. 3 ΨΨ, 4 ɗɗ, 2 DN, apparently syntypes, slides numbered 27/1, 31/6, 31/7, no other data (BSCZ).
Redescription. Female. Strongly sclerotised, brown.
Dorsal idiosoma (Fig. 53). Length ca 1045 μm, width ca 835 μm. Dorsal shield subcircular, cuticle smooth, with characteristic ornamentation of distinctive and deep circular pits over the whole shield surface. Marginal shield smooth, with numerous lyrifissures (id), completely separated from dorsal shield; with a pair of strongly sclerotised longitudinal ridges. Dorsal setae numerous, long and robust. Submarginal setae robust, marginal setae numerous, long, robust and hook-like.
Ve n t r a l idiosoma (Fig. 54) ornamented with small oval pits, except for smooth antero-lateral areas on sternal shield and posterior half of epigynial shield, and mostly smooth area of opisthosoma between coxae IV.
Sternal setae (st1–st5) long; st1 located clearly anterior to anterior edge of epigynium, st2–st5 lateral to epigynium. Epigynium tongue-shaped, entirely covered with numerous small oval pits. Opisthosoma ornamented with small oval pits. Ventral setae (v1–v5) robust, v1 = length v2; setae v4 and v5 located on shield, not on tubercles. Adanal setae Ad1 very short, Ad2 = 2 x Ad1, robust. Unpaired seta Pa = Ad2. Anal opening small, oval. Peritremes V-shaped. Tritosternum 6-branched, with broad base, laciniae finely serrated distally (Fig. 57).
Gnathosoma. Epistome narrow, laterally serrated, bifid distally, anterior process finely serrated (Fig. 55). Hypostomal setae h1 very long, simple; h2 lanceolate, serrated; h3 lanceolate, distally serrated; h4 lanceolate, serrated. Hypostomal surface covered with fine denticles of varying sizes; denticles grouped in single row at the level of setae h2 and distributed irregularly between setae h3–h4. Hypostomal groove finely serrated (Fig. 56). Ventral setae pv1–pv2 on palp trochanters robust, pv1 asymmetrically V-shaped, pv2 simple (Fig. 59). Chelicerae of average length, fixed digit with globular sensillus and denticle in form of small nodule on the internal surface, movable digit shorter than fixed digit, with single denticle on the internal surface (Fig. 58).
Legs. Structure and chaetotaxy typical for the genus.
Male. Strongly sclerotised, brown.
Dorsal idiosoma. Length ca 1100 μm, width ca 850 μm. Ornamentation and chaetotaxy as for female.
Ve n t r a l idiosoma (Fig. 60). Sternal region and anterior part of opisthosoma ornamented with large circular pits. Operculum oval, with a pair of short eugenital setae, located between coxae III and IV. Sternal setae simple; st1–st4 very short, st5 long. Two pairs of glands located near setae st4. Ornamentation and chaetotaxy of opisthosoma and peritremes as for female.
Gnathosoma. Epistome as for female, anterior process finely serrated. Hypostomal setae h1 long, simple; h2 short, simple; h3 a blunt rounded dome, diameter 4 µm; h4 short, serrated, located far from hypostomal axis (Fig. 61). Hypostomal groove finely serrated. Ventral setae on palp trochanters pv1 robust, serrated, pv2 simple, short. Palp tarsi with a pair of very elongated, robust setae.
Legs. Structure and chaetotaxy as for female, except dorsal setae d on genu and tibia I short, robust. Setae av on genu and tibia of leg II robust (Fig. 62). Trochanters III with a strong ventral process.
Deutonymph. Partly sclerotised, colour yellowish to light brown.
Dorsal idiosoma (Fig. 63). Length ca 960 µm, width ca 835 µm. Dorsal shield subcircular, ornamented with oval pits, marginal shield absent. Anterior end of idiosoma with single cuticular process. Dorsal setae numerous, lanceolate; some of them accompanied by circular pores. Between the setae ca 6 pairs of dorsal lyrifissures (id). Submarginal setae lanceolate. Marginal setae very numerous, curved, lanceolate.
Ve n t r a l idiosoma (Fig. 64). Sternal shield amphora-shaped, with distinctly widened base, distinctively ornamented in central and posterior part, extending behind coxae IV. Sternal setae st1-st4 simple, short, st5 long, lanceolate. Two pairs of lyrifissures: iv1 near camerostome, iv2 behind setae st5. Ventral shield wide, smooth; ventral setae lanceolate, long, between v4 and v5 two pairs of additional setae (v4 a and v4 b); v1 = length v2. Setae v1, v2 and v5 accompanied by circular pores. One pair of lyrifissures (iv3) located near setae v2. Anal shield subtriangular, with anal opening covered by a small valve and a pair of very short setae Ad1. Setae Ad2 and Pa on shield surrounding the anus, Ad2 = Pa. Peritreme long, with characteristic curve at level of coxae II, without poststigmatic extension, prestigmatic section reaching camerostome, stigmata at level of coxae III. Tritosternum 6-branched, with broad base.
Gnathosoma. Epistome narrow and serrated, distally bifid. Hypostome as for female.
Legs. Structure and chaetotaxy as for female.
Protonymph and Larva. Unknown.
Ecology. This species was recorded by Hirschmann & Zirngiebl-Nicol (1969a) from Spain, from the litter of oak-chestnut forest (Fig. 1).
