description: <i>Teutamus christae</i> sp. nov. · (Figs. 6-10) Diagnosis. Within the seven species of this poorly known genera recorded from Thailand (northern Malay Peninsula), Malaysia (Malay peninsula and Borneo) and Indonesia (Smnatra and Java), this new species resembles <i>Teutamus</i> vittatus Deeleman-Reinhold, 2001, described from Mount Kinabaru National Park, at 1550m in elevation, North Borneo, Sabah, Malaysia, but can be distinguished from the Bornean spider by the details of male palp, especially by the shape of the tibial apophysis and the conductor. This is the new record of the genus in Vietnam. Type <i>specimen.</i> Holotype: male from Bach Ma National Park, ea. 1200 m in elevation, Thua Thien Hue Province, Central Vietnam, 5-V- 2003, by sifting method in broad-leaved forest H. Ono leg. (NSMT-Ar 8350). ' Description (holotype). Measurement: Body length 5.25 mm; pro soma length 2. 70 mm, width 1.99mm; opisthosoma length 2.54mm, width 1.50mm; lengths of legs [total length (femur+ patella+ tibia+ metatarsus+ tarsus)]: I 7.25 mm (2.02 + 0.81 + 1.88 + 1.60 + 0.94), II 6.33 mm (1.83 + 0.71 + 1.50 + 1.35 + 0.94), Ill 5.51 mm (1.54 + 0.75 + 1.13 + 1.28 + 0.81), IV 8.14mm (2.22 + 0.79 + 1.84 + 2.16 + 1.13). Prosoma (Fig. 6): Carapace longer than wide (length/width 1.36), tubercular, with a median furrow distinct and rounded, anterior margin strongly sclerotized and expanded at the middle between proximal part of both the chelicera. Eyes: anterior eye row recurved and posterior eye row straight in dorsal view, all eyes almost same in size, but AME the largest and PME the smallest, PMA somewhat modified, AME-AME= AME-ALE, PME-PME=PME-PLE, clypeus much shorter than the anterior width of median ocular area (4: 7), median ocular area just a square. Labium rectangular, slightly longer than wide (length/width 1.25), its posterior margin forming a sclerotized edge with a notch at the middle, sternum longer than wide (length/width 1.25), its margin also forming edge strongly sclerotized. Chelicera furnished with three teeth on promargin of fang furrow and two small teeth on retromargin (Fig. 7). Legs: relatively short and thick, with spines on following segments. Femora: I prolaterally 0-0- 0-0-1-1, IV dorsally 1-0, tibiae: I ventrally 2- 2-2-2-2-2-2, II ventrally 2-2-2-2-2, Ill ventrally 1-2-1 (apical), IV pro- and retrolaterally 0-1, ventrally 1-1-2 (apical), metatarsi: I-ll ventrally 2-2-2-2, III-IV pro- and retrolateraly each 1, Ill ventrally 2-0-0, IV ventrally 1-2. All femora furnished with many fine and long hairs on the dorsal surface. Coxae of legs relatively long and its apical pmt visible in dorsal view. Leg formula: IV-I-ll-Ill. Male palp (Figs. 8-10): Patella simple, retrolateral apophysis of tibia spatulate and wide at the base, cymbium dorso-apically with hair tuft, tegulum large, apically with a digitiform conductor, embolus not visible in ventral view. Opisthosoma (Fig. 6): cylindrical, much longer than wide (length/width female 1.69), with a dorsal scutum very wide and extending to the ventral side. Anterior spinnerets cylindrical and much thicker than the posterior spinnerets, medi­ an spinnerets small, colulus present but indistinct. Coloration and markings: Carapace red-blackish brown, chelicerae, maxillae, labium and sternum chestnut brown, legs brown, lighter in distal segments; opisthosoma with a dorsal scutum brown and the posterior part grey with white spots, ventrally white with four stripes made by brown spots, spinnerets light yellowish brown. Distribution. Central Vietnam (at present known only from the type locality). Etymology. The new species is dedicated to Dr. Christa Deeleman-Reinhold, Ossendrecht, The Netherlands, who made efforts in forest spiders of Southeast Asia. Remark. Female unknown.
