Type material: Holotype: male, LAOS, Luang Prabang Province, Phou Khoun, Tham Seua, N 19°20'35.8'', E 102°26'19.1'', 1226 m altitude, path to cave, shady slope, 18 February 2009, by night, by hand, P. Jäger leg. ( SMF, PJ 3364, SD 679).
Etymology. The Lao word “ süung ” means “high”, referring to the relatively high altitude of the type locality; term in apposition.
Diagnosis. Medium-sized Sparassinae (total length male 11.0). According to the complex embolus (basal part with bulge and indentation as well as tip with coil and bend) this new species may be related to O. muang Jäger and Praxaysombath, 2009 from Khammouan Province, Laos. It is distinguished from other Olios spp. by the triangular, strongly pointed tegular apophysis in combination with the characteristic distal coil of the embolus. Base of embolus with outgrowth (recognisable in ventral view).
Description. Male: PL 5.2, PW 5.1, AW 2.9, OL 5.8, OW 4.1. Eye diameters and interdistances: AME 0.36, ALE 0.33, PME 0.31, PLE 0.31, AME–AME 0.28, AME–ALE 0.19, PME–PME 0.46, PME–PLE 0.49, AME–PME 0.40, ALE–PLE 0.26, clypeus AME 0.19, clypeus ALE 0.26. Palp and leg measurements: palp 7.6 (2.3, 1.1, 1.5, -, 2.7), I 28.5 (7.7, 3.0, 8.0, 7.6, 2.2), II 31.3 (8.6, 3.2, 8.7, 8.5, 2.3), III 22.8 (6.8, 2.4, 6.1, 5.5, 2.0), IV 25.0 (7.5, 2.3, 6.6, 6.6, 2.0). Leg formula 2143. Spination of palp and legs: palp 131, 211 (bristles), 0011; femora I–III 323, IV 322 (median spine small); patellae I 1 (0)00, II 100, III 1 (0)00, IV 000; tibiae I 2124, II 3034/2124, III 2124, IV 2114; metatarsi I–III 2024, IV 3026. Metatarsus IV distally with small ventral spine, few bristles and scopula. Chelicera with 2 anterior, 5 posterior teeth, and without denticles. Cheliceral fang joint with 6 bristles. Palpus as in diagnosis. Embolus arising in a 7-o’clock-position from tegulum, with simple tip; conductor concave in ventral view, round in lateral view, arising disto-medially from tegulum. Tegular apophysis arising proximo-centrally from tegulum. RTA tapered, with distal finger-like tip. Dorsal cymbium with scopula in distal half. Cymbium elongated oval ( Figs 9–12 View FIGURES 9 – 12 ).
Colouration in ethanol ( Figs 24–26 View FIGURES 13 – 26 ). Yellow brown with dark markings. Dorsal shield of prosoma with small patch in front of fovea, with median line between fovea and eyes and two lines from PLE running posterior; region at anterior eye row dark. Sternum and ventral coxae pale yellowish-brown, without distinct pattern; posterior half of sternum with indistinct patches; labium and gnathocoxae brown with distal white lip, gnathocoxae with oval white patch at slightly bulgy proximal part. Chelicerae dark especially in distal half, proximal half with each 3 indistinct longitudinal lines. Palp and legs yellowish brown with distal segments darker. Dorsal opisthosoma with characteristic pattern as in O. jaenicke spec. nov., but darker, with 6 pairs of bright patches decreasing in size posteriorly. Lateral opisthosoma with many lines most of them fused together. Ventral opisthosoma with distinct irregular pattern consisting of patches in front of and behind epigastric furrow.
Female: Unknown.
Distribution. Known only from the type locality ( Figs 27 View FIGURES 27 – 29. 27 : 1, 28).
