Diagnosis
Diagnosis.— A large, pale species with a series of conspicuous transverse black bars on the abdomen. A further distinctive character is the double, prong-shaped tibial apophysis in the male palp. The vulva is similar to that in ornatissima but can easily be recognised by the large lateral depression bordered by a semicircular hood.
Description
Description.— MALE. Total length 3.50 mm. Carapace length 1.65 mm, width 1.30 mm, head width 0.90 mm, eye group width 0.50 mm; abdomen 1.75 mm long, 1.20 mm wide. Leg lengths: leg I 6.30 mm (1.60-2.35-1.60-0.75), leg II 5.05 mm (1.35-1.80-1.25-0.65), leg III 4.35 mm (1.15-1.40-1.15-0.65), leg IV 6.45 mm (1.80-2.00-1.75-0.90), palp 0.60- 0.25-0.25+apophysis 0.20-0.65 mm. Carapace, mouthparts and legs orange, femora, patellae and tibiae with a vague grey subapical band, abdomen (figs 657-658) pale buff with dorsally at one third a black transverse band interrupted in the middle, followed by 5 transverse bands and a black ring around the spinnerets.

Chelicerae with 2 small teeth on the promargin and a third one near the base of the fang, a double tooth on the retromargin. Leg spination: all femora with 1 short dorsal spine proximally, femur I with 1-1-1-1pl, femur II with 1-1pd distally, tibia I with 7 pairs of ventral spines, tibia II 6-7 pairs of ventral spines, metatarsus I and II with 1-1 -1 -1pv and 1-1-1 rv, leg III and IV spineless. Abdomen dorsally with small scutum. Spinnerets fig. 661. Palp figs 659-660, femur with ventral ridge, tibia with a large apophysis consisting of a distally abruptly narrowing dorsal branch and a shorter retrolateral branch. FEMALE. Total length 4.15 mm. Carapace length 1.75 mm, width 1.40 mm, head width 0.75 mm, width eye region 0.50 mm; abdomen 2.50 mm long, 1.65 mm wide, epigyne 0.50 mm wide.
