Rotundabaloghia (Rotundabaloghia) wangi   sp. nov.

( Figs 12–20 View FIGURES 12 – 18 View FIGURES 19 – 24 )

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 View FIGURES 12 – 18 ). Marginal and dorsal shields fused. Four pairs of setae in row j short, smooth and needle-like (ca 38–40 Μm) ( Fig. 14 View FIGURES 12 – 18 ), other setae on dorsal idiosoma slightly pilose ( Fig. 13 View FIGURES 12 – 18 ) (ca 6–10 Μm). Dorsal idiosoma covered by oval pits ( Figs 13–14 View FIGURES 12 – 18 ).

Ventral idiosoma ( Fig. 15 View FIGURES 12 – 18 ). Sternal shield with some oval pits. Setae St 1, St 2 and St 3 long (ca 25–28 Μm), smooth and needle-like. Seta St 1 situated near anterior margin of sternal shield, St 2 at level of posterior margin of coxae II, St 3 at level of posterior margin of coxae III, St 4 very short (ca 6–7 Μm) and situated close to St 3. Seta St 5 absent ( Fig. 19 View FIGURES 19 – 24 ). Ventral setae ( Fig. 16 View FIGURES 12 – 18 ) smooth and needle-like (V 2, V 6, V 7 and ad) or marginally pilose (V 8). V 2 (ca 24–25 Μm) situated near anterior margin of pedofossae IV, V 6 (ca 13–14 Μm) between V 2 and V 7, V 7 (ca 26– 28 Μm) at level of setae ad, V 8 (ca 14–15 Μm) placed near end of pedofossae IV. Setae ad similar in shape and length to V 6, 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 View FIGURES 19 – 24 ). Pedofossae deep, their surface smooth, separate furrows for tarsi IV present. One pair of lyriform fissures situated close to St 1, second pair close to basal edge of genital shield. Base of tritosternum narrow, tritosternal laciniae smooth, subdivided into four smooth branches ( Fig. 17 View FIGURES 12 – 18 ).

Gnathosoma   ( Fig. 17 View FIGURES 12 – 18 ). Corniculi horn-like, internal malae shorter than corniculi and smooth. Hypostomal setae: h 1 long (ca 20–21 Μm), smooth and needle-like, h 2 (ca 9–10 Μm), h 3 and h 4 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 View FIGURES 12 – 18 ).

Legs ( Figs 21–24 View FIGURES 19 – 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 View FIGURES 19 – 24 ). Four pairs of sternal setae situated anterior to genital shield, these setae smooth, needle-like. St 1, St 2 and St 3 long (ca 33–35 Μm), St 4 and St 5 shorter (ca 18–19 Μm). St 1 situated near anterior margin of sternal shield, St 2 situated at level of posterior margin of coxae II, St 3 at level of posterior margin of coxae III, St 4 and St 5 at level of anterior margin of genital shield. One pair lyriform fissured placed close to St 1, second pair between St 4 and St 5. 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).
