Type material: Holotype: female, LAOS: Khammuan Province: 15 km N Thakek, Tham  Pha Yot (“cave of the dropping cliff”), N 17 ° 32 ' 57.24 '', E 104 ° 48 ' 45.23 '' [200 m altitude], cave in limestone, aphotic zone, c. 25 °C, at day, by hand, 29 April 2012, P. Jäger leg. ( SMFAbout SMF, PJ 3366).

Additional material examined. LAOS: Khammuan Province: 1 subadult female, 18 km NNW Thakek, Ban Phalem, Tham  Koun Don, N 17 ° 33 ' 49.2 ", E 104 ° 52 ' 18.7 " E [206 m altitude], in cave, by hand, 24 February 2006, 197/06, H. Steiner leg., field number 197 /06, French Khammuan expedition ( SMFAbout SMF).

Diagnosis. Medium sized Heteropodinae, body length of female: 15.1. Females may be distinguished from other Sinopoda  species by having only two eye lenses (ALE: Fig. 73View FIGURES 66 – 75). Vulva similar to that of S. guap  spec. nov., but S. soong  spec. nov. is distinguished by the massive roughly quadrangular shape of its epigyne in ventral view ( Fig. 55View FIGURES 51 – 65). Epigynal pockets forming two semicircles in anterior view ( Fig. 56View FIGURES 51 – 65).

Etymology. The species name is derived from the Lao  word “ soong  ” meaning “two” and referring to the number of eye lenses; term in apposition.

Description. Female (holotype): Prosoma length 5.9, prosoma width 4.8, anterior width of prosoma 2.6, opisthosoma length 9.2, opisthosoma width 5.9. Eyes: two lenses without pigments present. ALE 0.09, ALE–ALE 0.61. Spination: Palp: 131, 101, 2121, 1114; legs: femur I–III 323, IV 321; patella I–III 0 0 1, IV 000; tibia I 2126, II–IV 2226; metatarsus I–II 1014, III 2014, IV 3036. Ventral leg metatarsi I–II with c. 10 short bristles distally, metatarsus III–IV with c. 20 bristles ( Fig. 72View FIGURES 66 – 75) and additionally with double row of bristles, the latter in III in proximal half, in IV along entire length ( Fig. 72View FIGURES 66 – 75). Leg formula: 2413. Measurements of palp and legs: Palp 11.0 (3.4, 1.5, 2.5, -, 3.6), leg I 34.4 (9.3, 3.5, 10.4, 9.1, 2.1), leg II 36.3 (10.3, 3.7, 11.0, 9.2, 2.1), leg III 32.2 (9.1, 3.2, 9.5, 8.4, 2.0), leg IV 34.6 (9.6, 3.2, 9.8, 9.8, 2.1). Cheliceral furrow with 3 anterior and 4 posterior teeth ( Fig. 74View FIGURES 66 – 75), and with restricted patch of c. 40 denticles close to anterior teeth. Margin of chelicerae close to fang base with one bristle ( Fig. 74View FIGURES 66 – 75). Palpal claw with 9–11 teeth ( Fig. 75View FIGURES 66 – 75). Sternum, ventral coxae and femora, distal legs as well as frontal chelicerae with long setae, otherwise with short setae.

Copulatory organ as in diagnosis ( Figs 55–60View FIGURES 51 – 65). Epigynal field as wide as long, with two very short anterior bands and one slit sensillum on the left side close to the field. Lateral lobes fused, posteriorly bilobal; bulging extremely ventrally. Glandular appendages short, only parts visible in anterior view. Spermathecae bulging to the dorsal side, fertilisation ducts arising posteriorly, long and narrowly laminar. Sclerotised spheres present dorsally and ventrally at median (fusion) line of lateral lobes. Expanded membranous sac reaching anterior end of duct system, shorter than that of S. tham  spec. nov., almost as long as wide.

Colouration in ethanol ( Figs 68 –71, 73View FIGURES 66 – 75): Uniformly yellowish-brown without pattern. Dorsal prosoma with cephalic part slightly darker than thoracic part, fovea and faint radial pattern slightly darker. Chelicerae reddish brown, labium and parts of gnathocoxae reddish-brown. Opisthosoma uniformly pale grey-brown. For colouration of live specimens see Figs 66–67View FIGURES 66 – 75.

Male. Unknown.

Distribution. Only known from the type locality ( Fig. 81View FIGURE 81).

Biology. Specimens were collected in the aphotic zone of the limestone cave. They were recorded together with specimens of Typopeltis magnificus Haupt, 2004  (Arachnida: Uropygi  : Thelyphonidae  ). In the entrance area (50–150 m apart) Heteropoda maxima  was recorded.
