Figs 13 a–c, 57 j–k

Type material: Holotype: female (SD 1592), INDOCHINA: Mission Dawydoff 1938/1939, entrance 23, 18 November 1960 ( MNHN).

Etymology: The species name is derived from the Latin word “flexura“ meaning “winding” and referring to the winding of the posterior part of the spermathecae; noun in apposition.

Diagnosis: Females of S. flexura spec. nov. can be distinguished from those of other Sinopoda species by the combination of the following characters of the posterior part of internal duct system 1. presence of one additional winding and 2. wider than anterior part.

Description: Female (holotype): Total length 13.50; prosoma 6.50 long, 5.50 wide, anterior width of prosoma 3.60; opisthosoma 7.00 long, 4.50 wide. Eye measurements: AME 0.26; ALE 0.41; PME 0.30; PLE 0.40; AME– AME 0.27; AME–ALE 0.11; PME–PME 0.38; PME–PLE 0.49; AME–PME 0.47; ALE–PLE 0.49; clypeus AME 0.40; clypeus ALE 0.38. Measurements of palp and legs: palp: 8.50 (2.60, 1.40, 2.00, 2.50); I: - (5.60, 2.70, 5.55, -, -); II: 22.10 (6.30, 2.90, 6.20, 5.00, 1.70); III: 18.60 (5.60, 2.50, 4.80, 4.20, 1.50); IV: 20.70 (5.90, 2.40, 5.30, 5.30, 1.80). Spination: palp: 131, 101, 2121, 1014; legs: Fe I–III 323, IV 321; Pa I–IV 001; Ti I–III 2026, IV 2126; Mt II 1014, III 2016, IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.

Colouration in ethanol: Prosoma reddish-brown, lateral and posterior part with brown semicircular pattern. Sternum yellow with brown margin. Opisthosoma dark brown, anterior part with cross-shaped pattern, ventral part medially yellowish-brown with brown spots, laterally with brown stripes. Chelicerae reddish-brown. Palps brown; Ti and Mt reddish-brown. Legs brown; Ti, Mt and Ta reddish-brown.

Copulatory organ as in diagnosis. Epigynal field longer than wide with two indicated anterior bands and two slit sensilla. Epigynal pockets running from latero-posterior to medio-anterior. Lobal septum narrow. Lateral lobes fused. Fusion bubble situated at posterior part of epigyne. Internal duct system wider than long. Spermathecae fused along median line. Glandular appendages laterad, extending only in anterior half of internal duct system, distally slender and straight. Fertilization ducts situated postero-laterally, very short and narrow.

Male: Unknown.

Distribution: Known only from the type locality.
