Figs 30 View FIGURES 30 a–e, 60 k–l, 61 a–b

Type material: Holotype: male ( PJ 896 ), MALAYSIA: Sarawak Province : Matang Reserve, under bark, April 1985, C.L. & P. R. Deeleman leg., adult sedentary 21 June 1985, dead 31 July 1985 ( RMNH).

Paratypes: 3 males ( PJ 902–904 , SD 1624) and 1 female ( PJ 905 ) with same data as for holotype except: 304 m, C.L. Deeleman leg. ( RMNH) .

Additional material examined: 1 female (without epigyne), 1 subadult female and 4 juveniles with same data as for paratypes ( RMNH) .

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

Diagnosis: Males of S. matang spec. nov. are similar to those of S. S. kambaiti spec. nov. ( Figs. 19 View FIGURES 19 a–c) in having an embolus tip with a spine that is only visible in prolateral view. They can be distinguished from the latter species by 1. eyes with AME largest (ALE largest and AME one-third smaller than ALE in S. kambaiti spec. nov.), 2. smaller body size reaching 6.20 (9.80 in S. kambaiti spec. nov.), 3. spermophore curved (nearly straight in S. kambaiti spec. nov.), 4. embolic apophysis shorter than embolus (longer than embolus in S. kambaiti spec. nov.), 5. embolus spine situated ventrally in prolateral view (situated dorsally in prolateral view in S. kambaiti spec. nov.), 6. conductor with distal part nearly two times as wide as proximal part (distal part nearly as wide as proximal part in S. kambaiti spec. nov.) and 7. vRTA rounded and median part wider than proximal part in retrolateral view and dRTA wide and curved in retrolateral view (vRTA tapering and median part as wide as proximal part in retrolateral view and dRTA small, straight and proximally with small spine in retrolateral view in S. kambaiti spec. nov.).

Females of S. matang spec. nov. are similar to those of S. tuber spec. nov. ( Figs. 48 View FIGURES 48 a–d) in having internal duct system with anterior median part bulging laterally and glandular appendages situated ventrally. They can be distinguished from S. tuber spec. nov. by 1. ALE smaller in diameter than AME (AME smaller in diameter than ALE in S. tuber spec. nov.), 2. lobal septum with anterior median indentation small (anterior median indentation wide in S. tuber spec. nov.), 3. glandular appendages diverging slightly posteriorly (running parallel in S. tuber spec. nov.) and 4. internal duct system fused along two thirds of median line and posterior part running parallel (fused along entire median line and posterior part bulging laterally in S. tuber spec. nov.).
