(Figs 25–38)
Material examined. Holotype. Female. Indonesia, Java, Cibodas, forest of Lithocarpus -Castanopsis above the botanical garden, at the tourist path near the waterfall, soil between buttresses of a large tree, ca. 1380 m, 26 November 1987, B. Hauser coll. Paratype. Two females and seven males, locality and date same as in holotype.
Description. Female. Length of idiosoma 310–320 Μm, width 270–280 Μm (n=3). Shape of idiosoma circular, posterior margin rounded, colour reddish brown.
Dorsal idiosoma (Fig. 25). Marginal and dorsal shields fused. All setae on dorsal idiosoma slightly pilose (Fig. 26) (ca 28–45 Μm). Dorsal idiosoma covered by oval pits.
Ventral idiosoma (Fig. 27). Sternal shield with some oval pits. All sternal setae, smooth and needle-like, St1, St2 and St3 longer (ca 13–17 Μm) than St4 (ca 5–6 Μm). Seta St1 situated close to anterior margin of sternal shield, St2 at level of anterior margin of coxae II, St3 at level of posterior margin of coxae III, St4 situated at level of anterior margin of coxae IV, St5 absent. Ventral setae (Fig. 16) smooth and needle-like. V2 (ca 11–12 Μm) situated near anterior margin of pedofossae IV, V6 (ca 13–15 Μm) almost at same level as V2, V8 (ca 27–28 Μm) near end of pedofossae IV, V7 (ca 25–26 Μm) halfway between V8 and ad. Setae ad similar in shape and length to V8, lateral to anal opening. Stigmata situated between coxae II and III. Prestigmatid part of peritremes hook-shaped, poststigmatid part short and straight. Genital shield long and linguliform, surface with oval pits, its apical margin with a small process (Fig. 33). Pedofossae deep, their surface smooth, separated furrows for tarsi IV present. One pair of lyriform fissures situated close to St1, second pair close to anterior margin of pedofossae IV, third pair to V8 and fourth pair near anal opening. Base of tritosternum narrow, tritosternal laciniae smooth, subdivided into four smooth branches (Fig. 29).
Gnathosoma (Fig. 30). Corniculi horn-like, internal malae longer than corniculi and smooth. Hypostomal setae: h1 long (ca 20–22 Μm), smooth and needle-like, h2, h3 and h4 short (ca 6–8 Μm), smooth and needle-like. Apical part of epistome slightly pilose, marginally serrate (Fig. 31). Palp with smooth setae except for one serrate seta on palp trochanter (Fig. 30). Fixed digit of chelicera longer than movable digit and bearing one central tooth and one apical sensory organ, movable digit without teeth. Internal sclerotised node present (Fig. 32).
Legs (Figs 35–38). All legs with ambulacral claws and smooth and needle-like setae, but the claws on first leg shorter than others. All femora bearing flap-like ventral process.
Male. Length of idiosoma 320–330 Μm, width 260–270 Μm (n=7).
Dorsal idiosoma. Ornamentation and chaetotaxy of dorsal shield as for female.
Ventral idiosoma (Fig. 34). Four pairs of sternal setae situated anterior to genital shield, these setae smooth, needle-like. St1 and St5 short (ca 12–13 Μm), St2 and St3and St4 longer (ca 21–24 Μm). St1 situated near anterior margin of sternal shield, St2 situated at level of central area of coxae II, St3 at level of anterior margin of coxae III, St4 at level of anterior margin of coxae IV, St5 at level of posterior margin of genital shield. Surface of sternal shield with numerous oval pits. Two pairs of poroids situated on sternal shield, first pair at level of central area of coxae II, second pair at level of central area of coxae III. Surface of ventral shield, position of lyrifissures and shape and size of ventral setae as in female. Genital shield circular and situated between coxae IV.
Larva and nymphs unknown.
Etymology. The name of the new species refers to the island (Java) where it was collected. Remarks. The short anterior process on the female genital shield, the length of the sternal setae, and the position of the ventral setae is a unique character combination within the South-East Asian members of the subgenus Circobaloghia Kontschán, 2010b.
