Diagnosis
Diagnosis. — Easily distinguished by the contrasting pattern of the carapace and abdomen, the large tibial apophysis with additional dorsal branch and the shape of the embolus and tegular apophysis in the male palp. Furthermore, in males there is a double row of long hair ventrally on the abdomen; in the epigyne the shape and position of the spermathecae are diagnostic.
Description
Description.— MALE. Total length 2.25 mm. Carapace length 1.15 mm, width 1.00 mm, height above leg III 0.30 mm, head width 0.45 mm, width PER 0.40 mm; abdomen 1.05 mm long, 0.70 mm wide. Leg lengths: leg I 4.65 mm (1.20-1.75-1.15-0.55), leg II 3.85 mm (1.00-1.35-0.90-0.60), leg III 3.55 mm (0.90-1.05-1.00-0.60), leg IV 5.15 mm (1.35- 1.50-1.50-0.80), palp 0.45-0.30-0.25-0.25 apophyse- 0.60 mm. Carapace pale yellow in the centre, dark grey in the periphery (figs 675-676), mouthparts and sternum pale yellow, chelicerae suffused with dark grey; femora dark grey, rest of legs pale yellow, abdomen lacking scuta, dorsally in the middle ivory white, rear third of abdomen and flanks dark grey with an ivory white subcaudal transverse band, underside white. AME a little larger than ALE, AME close together, PER somewhat recurved, PME a little smaller than PLE, PME sperated by 1/2 d, juxtaposed to PLE. Clypeus almost equal to 1 d AME. Chelicerae with 3 widely spaced promarginal and 2 retromariginal teeth, close together, the largest proximalmost. Leg spination: all femora without any dorsal spine, femur I with 1-1-1pd, tibia I and II with 6 pair of ventral spines, metatarsus I with 4 pairs, metatarsus II with 3 pairs, posterior legs spineless. Abdomen ventrally ornamented with a double longitudinal row of about 10 long curved setae, just behind the genital fold (fig. 676); a tuft of hair in front of spinnerets. Palp figs 677-678, femur not visibly modified ventrally, only somewhat compressed laterally and keeled; tibial apophysis enlarged and partly surrounding bulb, with an aditional dorsal branch. FEMALE. Total length 3.25 mm. Carapace length 1.30 mm, width 1.15 mm, head width 0.55 mm; abdomen 1.80 mm long, 1.25 mm wide, epigyne 0.40 mm wide. Leg lengths: leg I 5.65 mm (1.40-2.00-1.15-1.10), leg II 5.30 mm (1.20-1.60-1.45-1.05), leg III 3.90 mm (1.00-1.25-1.05-0.60), leg IV 5.90 mm (1.50-1.80-1.70-0.90), palp 0.45-0.25-0.30- 0.55 mm. Carapace, eyes, mouthparts and legs more yellowish than in male. Abdomen and legs less contrastingly coloured, sometimes a dark grey midline. Abdomen without rows of ventral setae, and without ventral pre-spinneret tuft. Epigyne (fig. 679) posteriorly with a pair of round spermathecae, separated by their diameter in front of which the very dark appearing openings; vulva fig. 680. Variation.— Total length males 2.0- 2.3 mm, females 2.2-3.1 mm.
Distribution
Distribution. — Only known from the Kinabalu area in Western Sabah. Etymology. — The word ornatus (Lat.) means decorated, embellished, both with contrasting colour pattern on carapace, abdomen and legs, as the fringe of long hair borne on the venter by males.
