Type material: Holotype: female, LAOS: Huaphan Province: Tham  Ma Liong, N 20 ° 24 ' 22.60 ", E 104 ° 14 ' 58.90 " [820 m altitude], cave in limestone, by hand, 17 January 2008, H. Steiner leg., field number 092/08, Northern Lao-European Cave Project ( SMFAbout SMF, PJ 3386).

Diagnosis. Medium-sized Heteropodinae, body length of female: 11.8. Females ( Figs 33–35View FIGURES 24 – 35) similar to those of S. steineri  spec. nov. in having a similar internal duct system with parallel part long, glandular appendages long and narrow, posterior part narrower than anterior part with glandular appendages, and to those of S. tham  spec. nov. in having a similar course of epigynal pockets and in lateral furrows sub-parallel, but are distinguished from these and other Sinopoda  spp. by 1. Posterior part of spermathecae bent strongly, running almost a U-turn (bent at right angle in S. steineri  spec. nov. and S. tham  spec. nov.), 2. Lateral lobes with strongly bilobal posterior margin (not so in other Laotian Sinopoda  species), 3. Lateral margins of epigynal pockets pointing anterio-laterally (pointing laterally in S. tham  spec. nov.).

Etymology. The species name is derived from the Lao  word “ peet  [bpεεt]” meaning “eight” and referring to the fact that all eight eyes are developed; term in apposition. Pronunciation note: the long vowel “εε” of the Lao  alphabet is pronounced as the “a” in the English “sad” or the “ä” in the German “gähnen”.

Description. Female (holotype): Prosoma length 4.7, prosoma width 4.2, anterior width of prosoma 2.7, opisthosoma length 7.1, opisthosoma width 4.2. AME 0.23, ALE 0.42, PME 0.29, PLE 0.42, AME–AME 0.15, AME–ALE 0.07, PME–PME 0.23, PME–PLE 0.39, AME–PME 0.37, ALE–PLE 0.35, clypeus AME 0.32, clypeus ALE 0.24. Spination: Palp: 131, 101, 2121, 1014; legs: femur I–III 323, IV 331; patella I–IV 000; tibia I–IV 2026; metatarsus I–II 0 0 0 4, III 2016, IV 3036. Ventral metatarsus I with short double row of stiff bristles proximally, II with a slightly longer row also restricted to proximal half, III with dense double row of bristles along entire length and IV with the same as in III but with additional dense distal patch of bristles. Leg formula: 2413. Measurements of palp and legs: Palp 7.3 (2.1, 1.2, 1.6, -, 2.3), leg I 20.7 (5.6, 2.3, 6.1, 5.0, 1.7), leg II 23.1 (6.5, 2.6, 6.8, 5.4, 1.8), leg III 19.5 (5.4, 2.7, 5.5, 4.7, 1.7), leg IV 21.3 (5.7, 2.2, 5.9, 5.6, 1.9). Cheliceral furrow with 3 anterior and 4 posterior teeth, and with ca. 45 denticles in elongated patch close to anterior teeth. Margin of chelicerae close to fang base with one bristle. Palpal claw with 8 teeth. Sternum, ventral coxae and ventral femora covered sparsely with long setae, chelicerae with dense cover of long setae, otherwise with shorter setae.

Copulatory organ as in diagnosis ( Figs 33–35View FIGURES 24 – 35). Epigynal field wider than long, with anterior bands fused with field and one slit sensillum on each side slightly separated from the field. Lateral lobes fused and with broad median incision. Epigynal pockets running from (anterio)-lateral to medio-anterior, where copulatory openings are situated. Lateral furrows situated apart from lateral ends of pockets, almost longitudinally oriented, distinct. Lobal septum moderately wide. Glandular appendages extending barely to posterior half of internal duct system. Posterior spermathecae bulging laterally, fertilisation ducts arising medially from the posterior part.

Colouration in ethanol ( Figs 43–45View FIGURES 36 – 45): Yellowish-brown. Dorsal prosoma yellowish-brown with fovea and cuticular radial pattern reddish-brown, posterior part with characteristic transversal bright and dark band. Sternum and ventral coxae pale yellowish-brown, gnathocoxae and labium reddish- to yellowish-brown. Chelicerae deep reddish-brown. Legs uniformly yellowish-brown, distally slightly darker. Dorsal opisthosoma with indistinct irregular pattern, ventral opisthosoma almost without pattern.

Male. Unknown.

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