description: <i>Otacilia parva</i> sp. n. (figs 670 - 674, map 34) <i>Type locality.</i> — Indonesia, W Sumatra, former “ Padangse Bovenlanden ”, Panti Reserve, north of Lebuksikaping. <i>Type</i> material.— Holotype &amp;male; from the type locality in leaf litter of lowland primary forest, 4.viii.82, C.L. and PR. Deeleman; paratypes: 1 &amp;male;, 5 &amp;female;, same data. <i>Other material</i>.— None. <i>Diagnosis</i>.— Small species with reduced pigmentless PLE, femora II-IV with two dark rings. The genital organs are unusual and cannot be confounded with other species: the male palpal tibia has a large U-shaped apophysis bearing an anterior projection; the embolus is large and tapering, the tegular apophysis is lacking. The epigyne <i>is</i> relatively small and far removed from the epigastric margin, with dark coloured openings (plugs?) and bean-shaped spermathecae; no bursae were observed. <i>Description</i>.— MALE, holotype. Total length 1.70 mm. Carapace length 0.85 mm, width 0.70 mm, head width 0.30 mm, eye group 0.25 mm, height 0.25 mm; abdomen 0.85 mm long, 0.60 mm wide. Leg lengths: leg I 3.05 mm (0.80-1.00-0.80-0.45), leg II 2.60 mm (0.70-0.80-0.60-0.50), leg III 2.30 mm (0.60-0.70-0.60-0.40), leg IV 3.35 mm (0.90-1.10- 0.95-0.40), palp 0.20-0.12-0.20- 0.40 mm. Carapace, mouthparts and legs orange, carapace with wide dark band along lateral and posterior margin, femora II-IV with two dark bands; abdomen dark grey, in posterior half with white transverse lines (fig. 670), venter light. Eyes (fig. 670): diameter PME half that of PLE and lacking pigment ring, separated by their d. juxtaposed to laterals. Leg spination: femur I with 1-1-1 pl, tibia I with 6 pair of ventral spines, tibia II with a row of 6pv and 5rv; metatarsus I with 4 ventral pairs, metatarsi II with 1-1-1-1 <i>pv</i>, 1-1-1rv, posterior legs spineless. No apical brush on posterior metatarsi; coriaceous dorsal scutum over half of abdomen length, ventrally a small bulge with hairbrush in front of spinnerets. Palp figs 671-672 and diagnosis; femur with ventral keel, cymbium with retrolateral groove opposite tibia, embolus long, almost reaching tip of cymbium. FEMALE. Total length 2.00 mm. Carapace length 1.00 mm, width 0.80 mm, head width 0.40 mm, width eye region 0.32 mm, abdomen 1.05 mm long, 0.72 mm widem, epigyne 0.30 mm wide. Leg lengths: leg I 3.62 mm (1.00-1.32-0.80-0.50), leg II 3.00 mm (0.80- 1.00-0.70-0.50), leg <b>III</b> 2.85 mm (0.80-0.90-0.70-0.45), leg IV 4.20 mm (1.05-1.30-1.15- 0.70), palp 0.40-0.15-0.20- 0.32 mm. Carapace, eyes, mouthparts and legs as in male. Abdomen lacking scutum, venter lacking hairbrush. Epigyne and vulva small and appearing relatively poorly developed, reminiscent of a pre-adult stage, but each of the five females similar and the elements (except bursae) clearly recognisable and probably adult. Epigyne fig. 673, vulva fig. 674 and diagnosis, appearing as a pair of round spots in the frontal part of the epigynal area, with a bean-shaped sclerotization on the anterior edge. <i>Distribution</i>.— Only known from type locality. <i>Etymology.</i> — The word <i>parva</i> (Lat.) means small.
