description: <i>Plynnon longitarse</i> sp. n. <i>Type locality.</i> — Indonesia, C Kalimantan, 2°02/ <b>S</b>, 11°35'E, primary forest. <i>Type material.</i> — Holotype &amp;male;, “ Tumbang Tahai”, primary peat bog forest, 2-13.ix. 1985, S. Djojosudharmo; in the same area occurs <i>P. zborowskii',</i> paratypes: 1 &amp;female;, “ Kaharian ”, 2°02'S 11 °40'E, same data. <i>Other</i> material.— None. <i>Diagnosis</i>.— Characterized by the male palp with femoral boss covered with black teeth and by the different spatial arrangement of parts of vulva visible through the tegument. Further distinguishable from <i>zborowskii</i> by the less contrastingly coloured legs with entirely dark femora II-IV. <i>Description</i>.— Male. Total length 2.65 mm. Carapace length 1.25 mm, width 1.00 mm, height at coxae II 0.45 mm, head width 0.55 mm, eye group width 0.40 mm; abdomen 1.25 mm long, 0.90 mm wide. <i>Leg</i> lengths: <i>leg</i> I 3.00 mm (0.85-1.10-0.55-0.50), <i>leg II</i> 2.70 mm (0.80-0.95-0.50-0.45), leg III 2.50 mm (0.70-0.80-0.55-0.45), leg IV 3.90 mm (1.10-1.25-0.95-0.60), palp 0.45-0.22- 0.22-0.50 mm. Carapace, mouthparts and sternum dark chestnut brown, legs paler, anterior coxae pale brown, posterior coxae yellow, all femora dark. Abdomen dark and shiny dorsally, ventrally a little paler, without pattern. Both eye rows slightly recurved, in both rows lateral eyes larger than median eyes. Clypeus protruding, a little larger than d ALE. Underside of cephalothorax fig. 723. Leg spination: tibiae I with 1-1-1-1- 1 <i>pv</i>, 1-1-1-1rv, tibia II <i>with</i> 1-1-1-1pv <i>and</i> 1-1-1rv; metatarsi I and II with 1 pair of long strong spines ventrally. Abdomen entirely covered with scutum, ventrally an epigastric scutum only; spinnerets fig. 728. Palp figs 724-725, femur with conspicuous retrolateral boss, covered with black teeth of various size; embolus relatively very short. FEMALE (figs 721-722). Total length 2.30 mm. Carapace length 1.30 mm, width 1.00 mm, height 0.35 mm, head width 0.55 mm, eye group width 0.40 mm; abdomen 1.35 mm long, 0.87 mm wide, epigyne 0.35 mm wide. Leg lengths: leg I 2.80 mm (0.85-0.95-0.50- 0.50), leg II 2.95 mm (0.90-1.00-0.60-0.45), leg III 2.60 mm (0.75-0.80-0.60-0.45), leg IV 4.15 mm (1.20-1.35-1.00-0.60), palp 0.40-0.20-0.25- 0.45 mm. Carapace, eyes, mouthparts and legs as in male. Abdomen dorsally with a transverse white band with white setae. Spinnerets figs 727, 729. Epigyne and vulva fig. 726. <i>Distribution</i>.— Only known from type locality, the boggy lowland forests of Central Kalimantan, where it lives together with <i>P. zborowskii.</i> When writing this, (1998), the peat swamp forests of Kaharian and Tumbang Tahai, only known home for this rare species, have been converted to oil palm plantations. <i>Etymology</i>.— <i>longitarse,</i> Latin, refers to the tarsi I which are almost as long as metatarsi I.
