Sesieutes minor sp. n.
(figs 757- 761, map 38)

Type locality. — Borneo, W Sabah, Kinabalu National Park, 1550 m.

Type material.— Holotype ♂ from the type locality, forest opposite administration building, in leaf litter, 23-28.vii. 1980, P.R. and C.L. Deeleman; paratypes: 3 ♂, 1 ♀, same data, taken together with 1 ♂ of S. borneensis.

Other material.— Brunei, 1 ♂, Kuala Belalong, West Ridge, 8.ii. 1992, R. Snazell (B 335) can probably be attributed to this species.

Diagnosis. — A small, flat, orange coloured species with punctiform PM eyes and a pattern on the dorsum. Males differ from those in species of the lucens group by the absence of a distal apophysis on the palpal tibia; the femur is impressed distally. The size and number of spines on the anterior legs are reduced. Further distinctive features are the long, Vshaped dark grey mark on the pale venter and a dark circle around the spinnerets.

Description. — MALE, holotype. Total length 3.50 mm. Carapace length 1.70 mm, width 1.25 mm, height at coxae II 0.50 mm, head width 0.80 mm, width eye group 0.55 mm; abdomen 1.85 mm long, 1.10 mm wide. Leg lengths: leg I 5.35 mm (1.50-1.95-1.00-0.80), leg II 4.25 mm (1.25-1.50-0.80-0.70), leg III 3.55 mm (1.00-1.15-0.85-0.55), leg IV 5.50 mm (1.50-1.75-1.35-0.90), palp 0.60-0.25- 0.25-0.70 mm. Carapace, sternum and mouthparts glossy orange, carapace in the periphery with some large round pits, legs pale orange, patellae and tips of tibiae pale yellow; abdomen dark reddish grey with one or two pairs of dorso-lateral round pale orange areas (fig. 757), a glossy scutum of variable length, mostly about 7/s, reaching in front of a white area above the spinnerets; venter pale with a long, V-shaped dark grey mark and a dark ring around the spinnerets. Anterior eyes close together, AME larger than ALE, posterior eyes equidistant, PME punctiform. Clypeus barely 1 d AME. Leg spination: ventral surface of tibiae not flattened, spines relatively small, femur I with 0-0-1 pl, femur IV with l-0-0d, tibia I with 2-2-2-2v, tibia II with 1-1-1v, tibia III with 2-2v and 0-1 pl, tibia IV with 2-2v or 2-1 v and l-0pl or 1-1 pl and l-0rl or 1-1rl; metatarsus I with 2-2v, metatarsus II with 1-lv or l-2v and 0-1 pl, metatarsus III 2 -0v or 2-1 v and 1 pl spine, metatarsus IV with 2-1v and 1-0 pi and 1-0 rl. Dorsal scutum covering most of abdomen, ventral scutum with narrow collar with 1-2 shallow grooves. Palp (figs 758-759) with an excavation on the distal-retrolateral portion of the femur, marked with a diagonal ridge, tegulum triangular in lateral view, expanded retrolaterally, embolus in a short apical coil perpendicularly to palpal axis.

FEMALE, paratype. Total length 4.50 mm. Carapace length 1.80 mm, width 1.45 mm, height at coxa II 0.50 mm, head width 0.85 mm, width eye group 0.55 mm; abdomen 2.65 mm long, 1.50 mm wide, epigyne 0.40 mm wide, 0.35 wide. Leg lengths: leg I 4.60 mm (1.35-1.75-0.80-0.70), leg II 4.30 mm (1.20-1.50-0.90-0.70), leg III 3.75 mm (0.95-1.25- 0.90-0.65), leg IV 5.40 mm (1.45-1.80-1.30-0.85), palp 0.60-0.30-0.35- 0.55 mm. Carapace, eyes, mouthparts, sternum and legs as in the male; abdomen with small dorsal scutum, dorsally grey, flanks and underside white, ventrally a long, dark grey V and a dark grey ring around the spinnerets. Leg spination as in the male. PM spinnerets distally with flattened oval truncation, not skewed, with 2 rows of 5-7 cylindrical gland spigots. Epigyne (figs 760 - 761) with large anterior openings and enlarged, strongly sclerotized entrance tubes, for the rest there is similarity with the vulva of nitens.

Distribution. — Only kown from NE Borneo.

Etymology. — The Latin word minor means: smaller than the other species.
