Type material: Holotype: female (SD 1623), MALAYSIA: Sabah Province: Tawau Hill Park , tree trunk, N04°23’57”, E117°53’17”, 330 m, 17 July 2017, N. Bay leg., collection number JK.17.07.19.0007 ( LKCNHM).

Etymology: The species name is derived from the type locality; term in apposition.

Diagnosis: Females of S. tawau spec. nov. can be distinguished from other Sinopoda species by the combination of the following characters: 1. antero-lateral margin of lateral lobes long and slightly curved, 2. glandular appendages situated ventrally of spermathecae, only distal part visible in dorsal view, 3. spermathecae in lateral view S-shaped, median part situated ventrally from anterior and posterior part and 4. posterior part of spermathecae wider than glandular appendages.

Description: Female (holotype): Total length 5.8; prosoma 2.70 long, 2.40 wide, anterior width of prosoma 1.50; opisthosoma 3.1 long, 1.8 wide. Eye measurements: AME 0.16; ALE 0.25; PME 0.20; PLE 0.26; AME–AME 0.10; AME–ALE 0.04; PME–PME 0.19; PME–PLE 0.19; AME–PME 0.23; ALE–PLE 0.20; clypeus AME 0.35; clypeus ALE 0.34. Leg formula: 2413. Measurements of palp and legs: palp: 3.90 (1.10, 0.60, 0.90, 1.30); I: 9.65 (2.75, 1.05, 2.60, 2.30, 0.95); II: 11.00 (3.10, 1.10, 3.05, 2.65, 1.10); III: 9.60 (2.80, 1.00, 2.60, 2.30, 0.90); IV: 10.35 (2.90, 1.00, 2.70, 2.70, 1.05). Spination: palp: 131, 101, 2121, 1004; legs: Fe I–III 323, IV 321; Pa I–IV 000; Ti I–IV 2026; Mt I–II 0004, III 3015, IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.

Colouration in ethanol: Prosoma dark brown, medially with wide yellow longitudinal stripe, lateral part with yellow stripe in posterior half. Strongly setose between ALE and PLE. Sternum yellowish-white with few dots in central part and brown patches at leg appendages. Opisthosoma brown, medially with reddish-brown stripe, along the latter with pairs of white dots, anterior part with white spot, laterally with yellowish-white spots, posteriorly with big white spot, ventrally yellowish-white with brown dots. Spinnerets laterally brown. Chelicerae reddish-brown with dark brown stripes. Palps whitish-yellow; Fe prolatero-proximally with brown spot, distal part with brown band, Pa distally brown, Ti proximally and distally with brown band, Mt distally brown. Legs whitish-yellow; Coxa ventro-distally with brown band, Fe medially and distally with brown spots, Pa distally brown, Pa III and IV distally with brown margin, Ti and Mt with brown patterning, Ta yellowish-brown.

Copulatory organ as in diagnosis. Epigynal field wider than long without anterior bands and slit sensilla. Epigynal pockets running from latero-posterior to medio-anterior. Lateral lobes fused, posteriorly with narrow median indentation. Lobal septum with median part wider than distal part. Fusion bubbles distributed over nearly entire epigyne. Internal duct system nearly as long as wide. Glandular appendages extending only in anterior half of internal duct system, short. Anterior and median part of spermathecae fused along median line without visible seam, posterior part bulging latero-posteriorly, curved. Fertilization ducts arising postero-laterally, short.

Male: Unknown.

Distribution: Known only from the type locality.
