Teutamus jambiensis View in CoL sp. n. ( figs 815-817 View Figs 812 - 814 , map 40 View Map 40 )

Type locality. — W Sumatra, Kerinci Seblat National Park .

Type material.— Holotype ♂ from the type locality, 800 m altitude, primary forest, from leaf litter, 21-30.vii.1988, S. Djojosudharmo et. al.; paratypes: 8♂,11♀, same data.

Other material. — None.

Diagnosis. — Distinct from preceding species by the ventral scutum in the male as long as the dorsal one, with straight truncation, and the double, partly membraneous apical projection on the male palpal bulb with apically a partly membranous conductor adjacent to a thornlike projection. Further, the more rounded lobes on the carapace, the presence of only 2 spines on femur I, the abdominal collar having 4 transverse ridges, the shape of the tibial apophysis and the size and position of the spermathecae are distinctive.

Description. — MALE. Total length 4.50 mm. Carapace length 2.05 mm, width 1.25 mm, height 0.70 mm, width head 0.65 mm at level of PER, width eye group 0.55 mm; abdomen length 2.50 mm, width 1.00 mm. Leg length: leg I 8.90 mm (2.20-3.20-2.15-1.35); leg II 6.80 mm (1.75-2.50-1.50-1.05); leg III 5.50 mm (1.50-1.70-1.40-0.90); leg IV 8.00 mm (2.15-2.45-2.15-1.25), palp 0.75-0.20-0.25- 0.70 mm. Colour of carapace, mouthparts, sternum and legs as in T. fertilis , legs with orange femora only, other leg segments pale yellow. Abdomen similar to that in fertilis . Carapace surface as in politus . AME clearly larger than ALE, closer together than in fertilis . Femur I with 2pl, tibia I with 8pv, 8rv, tibia II 8 pv, 8rv, metatarsus I 5 pv, 5rv, metatarsus II 5 pv, 4rv. Dorsal scutum covering more than 3/4 of abdomen; ventral scutum as long as dorsal scutum, with straight truncation, collar with 4 transverse grooves. Male palp fig. 815 View Figs 812 - 814 , tegulum apically with a partly membraneous conductor; a little lower down a small chitinous thorn-like apophysis.

FEMALE. Length 5.60 mm. Carapace length 2.25 mm, width 1.40 mm, height 0.75 mm, head width 0.80 mm, eye group width 0.65 mm, abdomen length 3.00 mm, width 1.80 mm. epigyne 0.30 mm wide, 0.25 mm long. Leg lengths: leg I 9.45 mm (2.40-3.60-2.10- 1.35), leg II 7.55 mm (1.90-2.85-1.70-1.10), leg III 6.30 mm (1.75-1.95-1.65-0.95), leg IV 8.50 mm (2.40-2.60-2.35-1.15), palp 0.60-0.20-0.40- 0.65 mm. Abdominal pattern more diluted than in male. Spine formula: tibiae with 8-10pv and 8-10rv, metatarsus I and II with 5pv, 4rv. Collar a little shorter than in male. Epigyne fig. 816 View Figs 812 - 814 ; vulva fig. 817 View Figs 812 - 814 , spermathecae widely separated, diagonal, small bursae attached to ducts.

Distribution.— Only known from Kerinci in W Sumatra.

Etymology.— From the name of the province Jambi, (in older atlasses spelled Djambi), type locality of this species.
