Holotype: Male; Indonesia, Sumatra, Jambi Province, Mt Kerinci, footpath to summit, N of Kersik Tua, 1800- 1980 m a.s.l., montane rain forest, sifting; 16.II.2000; leg. P. Schwendinger [Sum-00/12].
Paratypes: 1 male, 2 females; collected together with the holotype.
Diagnosis: The new species is characterized by the peculiar shape of its carapace and highly modified palpal tibia in the male, as well as by the rounded dorsal plate of the epigyne in the female.
Etymology: The specific epithet is a noun in apposition, referring to the long-nosed Russian fairy-tale character “Buratino”.
Description: Male (paratype). Large-sized Erigoninae, total length 3.13, habitus as shown in Fig. 1. Carapace modified (Figs 2-3), 1.65 long, 1.00 wide, reddish brown, with a pale, globular elevation in the middle. Anterior part of carapace protruded forwards, bearing anterior median eyes. Sulci situated at base of central globular outgrowth. Chelicerae 0.63 long, mastidion absent, anterior margin of fang groove with 5 strong teeth. Legs pale reddish brown. Leg I 6.93 long (1.95+0.35+1.78+1.55+1.30), leg IV 5.78 long (1.80+0.28+1.45+1.38+0.87). Chaetotaxy 2.2.1.1, length of spines about 2 diameters of segment. TmI 0.40. All metatarsi with trichobothrium. Palp (Figs 11-15): Tibia massive, highly modified. Proximal part of paracymbium narrow, middle part with a large rounded outgrowth, distal part hook-shaped. Suprategular apophysis complex, with several outgrowths. Column relatively large, looking like a spongy membraneous tissue. Median membrane narrow, protruded forwards. Radix very small, embolus thin, long, making two loops. Abdomen 1.50 long, 1.00 wide, dorsally pale, with several dark spots as shown in Fig. 1.
Female. Total length 2.75, habitus as shown in Fig. 4. Carapace 1.33 long, 1.00 wide, unmodified, reddish brown, with a pale spot in the middle. Chelicerae 0.63 long, anterior margin of fang groove with 5 strong teeth. Legs reddish brown. Leg I 6.34 long (1.68+0.38+1.65+1.53+1.10), leg IV 5.18 long (1.50+0.33+1.35+1.30+0.70). Chaetotaxy as in male. TmI 0.44. Abdomen 1.50 long, 1.05 wide, dorsal pattern as shown in Fig. 4. Epigyne (Figs 5-8, 16-18) prominent, aperture lacking, dorsal plate rounded, receptacles elongated.
Taxonomic remarks: The new species seems to be most similar to D. complexipalpis Millidge & Russell- Smith, 1992, known from males, but clearly differs by the shape of its carapace, by the arrangement of apophyses on the palpal tibia, as well as by the shape of the distal suprategular apophysis.
Distribution: Known only from the type locality on Sumatra Island, Indonesia.
