(Figs 12–20)
Material examined. Holotype. Female. Indonesia, Sumatra, (Sum-06/34) North Sumatra Province, Mt Sibayak, 4 km N of Brastagi, 3°13'16"N, 98°29'50"E, 1600m (primary forest); 7 July 2006, P. Schwendinger coll. Paratypes. One female and two males, locality and date same as in holotype.
Description. Female. Length of idiosoma 260–280 Μm, width 220–240 Μm (n=2). Shape of idiosoma circular, posterior margin rounded, colour reddish brown.
Dorsal idiosoma (Fig. 12). Marginal and dorsal shields fused. Four pairs of setae in row j short, smooth and needle-like (ca 38–40 Μm) (Fig. 14), other setae on dorsal idiosoma slightly pilose (Fig. 13) (ca 6–10 Μm). Dorsal idiosoma covered by oval pits (Figs 13–14).
Ventral idiosoma (Fig. 15). Sternal shield with some oval pits. Setae St1, St2 and St3 long (ca 25–28 Μm), smooth and needle-like. Seta St1 situated near anterior margin of sternal shield, St2 at level of posterior margin of coxae II, St3 at level of posterior margin of coxae III, St4 very short (ca 6–7 Μm) and situated close to St3. Seta St5 absent (Fig. 19). Ventral setae (Fig. 16) smooth and needle-like (V2, V6, V7 and ad) or marginally pilose (V8). V2 (ca 24–25 Μm) situated near anterior margin of pedofossae IV, V6 (ca 13–14 Μm) between V2 and V7, V7 (ca 26– 28 Μm) at level of setae ad, V8 (ca 14–15 Μm) placed near end of pedofossae IV. Setae ad similar in shape and length to V6, lateral to anal opening. Stigmata situated between coxae II and III. Presigtmatid part of peritremes hook-shaped, poststigmatid part short and straight. Genital shield long and linguliform, surface with irregular pits, its apical margin with a triangular process (Fig. 19). Pedofossae deep, their surface smooth, separate furrows for tarsi IV present. One pair of lyriform fissures situated close to St1, second pair close to basal edge of genital shield. Base of tritosternum narrow, tritosternal laciniae smooth, subdivided into four smooth branches (Fig. 17).
Gnathosoma (Fig. 17). Corniculi horn-like, internal malae shorter than corniculi and smooth. Hypostomal setae: h1 long (ca 20–21 Μm), smooth and needle-like, h2 (ca 9–10 Μm), h3 and h4 short (ca 6–7 Μm), smooth and needle-like. Apical part of epistome slightly pilose. Palp with smooth setae except for one slightly serrate seta on palp trochanter. Fixed digit of chelicera longer than movable digit and bearing two central teeth and one apical sensory organ, movable digit with one central tooth. Internal sclerotised node present (Fig. 18).
Legs (Figs 21–24). All legs with ambulacral claws and smooth and needle-like setae, but claws on first leg shorter than others. All femora bearing flap-like ventral process.
Male. Length of idiosoma 260–270 Μm, width 240–250 Μm (n=2).
Dorsal idiosoma. Ornamentation and chaetotaxy of dorsal shield as for female.
Ventral idiosoma (Fig. 20). Four pairs of sternal setae situated anterior to genital shield, these setae smooth, needle-like. St1, St2 and St3 long (ca 33–35 Μm), St4 and St5 shorter (ca 18–19 Μm). St1 situated near anterior margin of sternal shield, St2 situated at level of posterior margin of coxae II, St3 at level of posterior margin of coxae III, St4 and St5 at level of anterior margin of genital shield. One pair lyriform fissured placed close to St1, second pair between St4 and St5. Surface of sternal shield with numerous oval pits. Surface of ventral shield, and shape and size of ventral setae as in female. Genital shield circular and situated between coxae IV.
Larva and nymphs unknown.
Etymology. We dedicate the new species to our good friend Dr. Guo Quan Wang (University of Gunagxi, China).
