Diagnosis.— This species shares with S. scrobiculatus the sculpture of the carapace which consists of large round widely spaced cut depressions, but is distinguished from this and all other species by the large, angular eyes, with posterior eyes in a straight line, close together, the PME the largest and juxtaposed; further it is distinct from scrobiculatus in the male palp by the short triangular apophysis in the male palpal tibia, which is flexed dorsalwards and the complex, two-branched median apophysis. It is distinguished from vivax by the punctated carapace, spineless femora and posterior metatarsi and by the much shorter tibial apophysis and triangular median apophysis, and the differently shaped anterior depression in the epigyne.

Description. — MALE. Total length 4.40 mm. Carapace length 2.00 mm, width 1.25 mm, height 0.88 mm, head width 1.00 mm, eye group width 0.65 mm; abdomen 2.20 mm long, 1.40 mm wide. Leg lengths: leg I 5.05 mm (1.35-2.00-0.90-0.80), leg II 4.55 mm (1.20- 1.70-0.85-0.80), leg III 4.10 (1.05-1.40-0.95-0.70), leg IV 6.25 (1.80-2.00-1.60-0.85), palp 0.64-0.32- 0.28-0.68 mm. Carapace, mouthparts, sternum, abdomen and femur I dark chestnut brown, rest legs a shade paler, anterior femora and patellae sometimes with a hue of grey. Carapace ( fig. 862 ) with widely spaced radiating rows of seta-bearing granules, each sunk in a large round pit; margin lined with triangular thorns, with a long seta arising from the side. Thoracic groove obsolete. Eyes ( fig. 862 ): AER procurved, AME, ALE and PLE of equal size and narrowly spaced, ALE-PLE=1 d, PER straight, PME almost double the diameter of other eyes and juxtaposed. Clypeus 1 eye diameter, rebordered, convex, small chilum without knob. Chelicerae bulging, geniculate. Sternum densely covered with round pits ( fig. 863 ). Leg spination: all legs spineless, sometimes 1-0v on posteror tibiae. Tarsal claws as in vivax . Abdomen covered almost entirely with dorsal and ventral scutum, a short grooved collar present ( fig. 863 ). Palp figs 864-865 ; tibial apophysis short and pointed.

FEMALE. Total length 5.00 mm. Carapace length 1.92 mm, width 1.48 mm, head width 0.92 mm; abdomen 2.72 mm long, 1.60 mm wide, epigyne 0.35 mm wide, 0.50 mm long. Leg lengths: leg I 5.00 mm (1.48-1.88-0.88-0.76), leg II 4.45 mm (1.40-1.55-0.80-0.70), leg III 3.65 mm (1.00-1.25-0.85-0.55), leg IV 6.00 mm (1.60-2.00-1.45-0.95), palp 0.68- 0.32- 0.25-0.55 mm. Carapace, eyes, mouthparts and leg colouring as in male. Abdomen mouse grey without markings. Anterior depression of epigyne trapezoid ( figs 866-867 ), anteriorly, with sides converging towards posterior spermathecae; spermathecae separated by posterior loop of insemination ducts.

Distribution. — Southern part of peninsular Thailand, Sumatra, Sulawesi, Lesser Sunda Islands. More southern in distribution than S. vivax and with preference for rainforest.

Etymology. — From English punctate, with depressions, derived from Latin punctum, a point.
