Figs 28 a–b, 60 g–h

Type material: Holotype: female ( PJ 907 , SD 1553), MALAYSIA: Sabah Province: Kinabalu National Park , 1550 m, litter, along the way, 21 July 1980, C.L. & P. R. Deeleman leg. ( RMNH).

Etymology: The species name is derived from the Latin word “maculatus” meaning “maculate” and referring to the spotted legs of the spider; adjective.

Diagnosis: Females of S. maculata spec. nov. are similar to those of S. xieae Peng & Yin, 2001 in having short and thickened glandular appendages. They can be distinguished from the latter species by 1. smaller body size reaching 5.30 (9.90 in S. xieae ), 2. lateral lobes without median indentation (with median indentation in S. xieae ), 3. lobal septum anteriorly with median indentation (anteriorly without median indentation in S. xieae ), 4. posterior part of spermathecae wider than anterior part (posterior part narrower than anterior part in S. xieae ) and 5. fertilization ducts arising postero-medially (postero-laterally in S. xieae ).

Description: Female (holotype): Total length 5.30; prosoma 2.40 long, 2.10 wide, anterior width of prosoma 1.20; opisthosoma 2.90 long, 1.60 wide. Eye measurements: AME 0.15; ALE 0.23; PME 0.19; PLE 0.23; AME– AME 0.08; AME–ALE 0.02; PME–PME 0.16; PME–PLE 0.18; AME–PME 0.20; ALE–PLE 0.19; clypeus AME 0.32; clypeus ALE 0.26. Leg formula: 2413. Measurements of palp and legs: palp: 3.70 (1.00, 0.70, 0.90, 1.10); I: 8.30 (2.20, 1.00, 2.20, 2.05, 0.85); II: 8.95 (2.50, 1.00, 2.40, 2.15, 0.90); III: 7.90 (2.30, 0.90, 2.00, 1.90, 0.80); IV: 8.65 (2.40, 0.90, 2.15, 2.30, 0.90). Spination: palp: 131, 101, 2120, 1004; legs: Fe I–III 323, IV 331; Pa I–IV 000; Ti I 1026, II–III 2026, IV 2126; Mt I–II 2024, III–IV 3036. Cheliceral furrow with 3 anterior and 4 posterior teeth.

Colouration in ethanol: Prosoma yellowish-white, laterally brown with dark brown stripes, lateral margin and eye region brown, ventrally with six brown spots at coxae. Sternum white with six big spots laterally. Opisthosoma yellowish-grey, median part with brown longitudinal stripe, posteriorly brown, white patch in front of spinnerets, laterally with yellowish-brown spots, ventrally yellowish-white with brown dots, posteriorly brown. Chelicerae long, yellowish-grey with brown stripes and dots, ventral part with brown spots. Palps yellowish-grey; Fe and Pa proximo-laterally brown, distally Fe with brown spots, Pa with one brown spot, Ti proximally with brown spot, distally with brown dots, Mt proximally brown, distally reddish-brown. Legs yellowish-grey with brown dots; Fe median part brown, Ti medially and distally brown, Mt dorsally brown stripe.

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. Lobal septum anteriorly with median indentation. Fusion bubbles situated medially and anteriorly on epigyne. Internal duct system longer than wide. Glandular appendages extending only in anterior half of internal duct system. Spermathecae running parallel and fused along median line. Posterior part developed as separated tubular part. Fertilization ducts narrow.

Male: Unknown.

Distribution: Known only from the type locality.
