Teutamus rhino sp. n, ( figs 818-823 , map 40 )

Type locality. — W Java, Ujung Kulon Reserve .

Type material.— Holotype ♂ from the type locality, swampy primary forest, from leaf litter, 19-25.xi. 1986, S. Djojosudharmo et. al.; paratypes: 11 ♂, 14 ♀ from the type locality, same data .

Other material.— None.

Diagnosis. — Distinct from jambiensis by the pattern of the abdomen with oval white spots ventro-laterally in the pre-anal area, the less elongate carapace and in the male palp the tibial apophysis with more acute lower apophysis and the straight spinelike conductor. The present species can be separated from rothorum in the male by the presence of an uptilted distal tibial apophysis. In the epigyne long sinuous ducts and round spermathecae are visible.

Description. — MALE. Total length 4.45 mm. Carapace length 2.25 mm, width 1.50 mm, height 0.75 mm, width head 0.90 mm, width eye group 0.70 mm; abdomen length 2.20 mm, width 1.30 mm. Leg length: leg I 8.45 mm (2.10-3.05-2.05-1.25); leg II 6.60 mm (1.75-2.40-1.45-1.00); leg III 5.65 mm (1.50-1.75-1.50-0.90); leg IV 8.10 mm (2.10-2.50- 2.25-1.25), palp 0.55-0.25-0.35- 0.75 mm. Colour of carapace, mouthparts, sternum and legs as in T. jambiensis , legs with red-orange femora only, other leg segments paler. Abdomen with distinctive pattern ( fig. 820 ): dorsally blackish with the exception of a long reddish median band in the anterior part, behind which in the middle a black transverse bar which is interrupted in the middle, running somewhat diagonally; dorsal white preanal spot laterally extended with “wings” which sometimes connect to a ventral white zone; this zone is separated from the spinnerets by a black semicirlce. Eyes as in jambi ­ ensis. Femur 1 with 2pl, tibia I with 9pv, 8-9rv, tibia II 8 pv, 8rv, metatarsus I 5-6 pv, 5-6rv, metatarsus II 5 pv, 4rv. Dorsal scutum covering more than 3/4 of abdomen; ventral scutum as long as dorsal scutum, collar with 3 transverse grooves, rear margin irregular, frayed. Male palp figs 818-819 , distal tibial apophysis as large as proximal one, uptilted, bulb apically with a chitinous spine-like conductor, no other apophysis apparent.

FEMALE. Total length 4.60 mm. Carapace length 2.15 mm, width 1.50 mm, head width 0.85 mm, eye group width 0.70 mm, abdomen length 2.50 mm, width 1.50 mm. Leg lengths: leg I 8.45 mm (2.10-3.15-2.10-1.10), leg II 6.70 mm (1.75-2.45-1.50-1.00), leg III 5.80 mm (1.50-1.80-1.50-1.00), leg IV 8.40 mm (2.25-2.65-2.50-1.00), palp 0.65-0.20-0.42- 0.65 mm; epigyne 0.45 mm wide, 0.40 mm long. Abdominal pattern more diluted than in male, dorsal pattern white on a grey background, ventral surface of abdomen white except for the black pre-anal semicircle. Collar a little shorter than in male, with 1-2 grooves. Spine formula: tibiae I and II with 9 pairs, metatarsus I with 6, metatarsus II with 5 pairs. Epigyne fig. 821 ; vulva figs 822-823 , spermathecae round, openings large and round, appearing plugged. The position and tilt of the ducts are variable so that each epigyne looks slightly different.

Distribution.— Only known from the Ujung Kulon Reserve in W Java.

Etymology.— From the presence of the last surviving population in Indonesia of the impressive Rhinoceros sondaicus for which the Ujung Kulon Reserve is known.
