(Figures 3g, 3h, 6e, 6f, 10 a-c, 11a-d, 12a-d)  
 Diagnosis — Adult. Body size: 597–664× 365–431. Body surface with dense granulate microsculpturing; notogaster and partially anogenital region foveolate. Prodorsal processes connected medially at a relatively large distance; their anterior parts forming rounded prodorsal aperture. Rostral, lamellar and interlamellar setae slightly thickened; in shortest, erect. Bothridial seta with distinctly lanceolate head. Notogastral tubercle present. Distance between medial notogastral condyles comparatively short. Thirteen pairs of notogastral setae present: seta c long, with slightly phylliform basal part and attenuate mediodistal part, straight; other setae of medium length, thickened. Subcapitular seta h setiform. Seta l′ on trochanter III and v′ on leg trochanters III, IV long, thick.   
 Description of adult — Measurements – Body length: 664 (holotype: female), 597–   
664 (16 paratypes: four males and 12 females); body width: 431 (holotype), 365–431 (16 paratypes).  
Integument – Body color brown. Body surface with dense granulate microsculpturing. Tutorium and pedotectum I foveate. Region between bothridium and acetabula I–III densely tuberculate (diameter of tubercle up to 4). Notogaster with sparse foveolae (diameter of foveola up to 10). Anogenital region (except ventrolateral parts and region between genital and anal apertures) with more dense foveolae (diameter of foveola up to 10).  
 Prodorsum – Rostrum rounded. Lateral carinae fused medially before rostral margin. Lamella slightly developed. Prolamella present, but inconspicuous. Tutorium and prodorsal hollow of prodorsum well developed. Prodorsal processes connected medially at a relatively large distance. Anterior part of prodorsal processes have rounded prodorsal aperture (fused with prodorsal hollow) anteriorly to connecting region. Rostral (192–205), lamellar (180–192) and interlamellar (151–155) setae slightly thickened, slightly barbed; ro with slightly attenuate tip; le inserted on distinct tubercle; in erect. Distance in–le equally to le–ro. Slight carina developed between insertions of rostral setae. Bothridial seta (127–135) with long stalk and short, distinctly lanceolate head, roughened.   
 Notogaster – Notogastral tubercle present. Distance between medial notogastral condyles comparatively short (distinctly shorter than distance between setae lm–lm). Thirteen pairs of notogastral setae present: seta c (114–118) with phylliform basal part and attenuate mediodistal part and flexible tip, roughened, straight, directed anteromediad; h 3, p 1 – p 3 (57–65) and others (82–90) thickened, barbed. Opisthonotal gland opening and all lyrifissures distinct.   
 Gnathosoma – Mostly similar to Leobodes becki n. sp. Subcapitulum size: 143–151 × 123–131. Subcapitular setae (a: 16; m, h: 65–69) with attenuate tip, slightly barbed; a thinnest. Palp length: 73–77. Length of postpalpal seta: 10. Chelicera length: 180–188. Length of cha: 53–57; chb: 22–24.   
 Epimeral and lateral podosomal regions – Epimeral setae 1b, 3b, 4a (41–49), 3c, 4c (61–69) thickened, barbed; other setae (24–32) thin, with attenuate tip, slightly barbed; 4c thickest. Ventrolateral tubercle on epimere II distinct. Discidium with triangular tip.   
 Anogenital region – Genital seta (28–32) thin, with attenuate tip, slightly barbed. Aggenital (36–41), anal (36–41) and adanal (ad 1, ad 2: 49–53; ad 3: 36–41) setae thickened, barbed. Adanal lyrifissure distinct.   
 Legs – Mostly similar to Leobodes becki n. sp., but seta l′ on trochanter III and v′ on trochanters III, IV long, thick.   
 Material examined — Nepal, Panchthar District, Dhorpar Kharka, 27°05′N, 87°55′E, 2700   
 m a.s.l., soil-litter in mature Rododendron -Lithocarpus forest (sample No. 324), 13–16.IV.1988 (collected by J. Martens and W. Schawaller).   
 Type deposition — The holotype and one paratype are deposited in the collection of the SMNH ; 15 paratypes are deposited in the collection of the TSUMZ.   
 Etymology — The specific name is dedicated to Dr. Wolfgang Schawaller, well known entomologist, active participant and collector of the J. Martens expeditions to various parts of Europe and Asia, until recently working at State Museum of Natural History, Stuttgart, Germany.   
 Remarks — Leobodes schawalleri n. sp. differs from all representatives of the genus by the presence of 13 pairs (versus 10) of notogastral setae.
