description: <i>Teutamus brachiatus</i> sp. nov. (Figures 1 E, 2 F, 7 A–F) <i>Diagnosis</i> Males of <i>T. brachiatus</i> sp. nov. closely resemble those of <i>T. fertilis</i> in having a more or less spherical tegulum but can be distinguished by the more elongate conductor (Figure 7 A); females can be recognized by the abruptly bent insemination duct at its half length (Figure 7 E,F). <i>Type material</i> <i>Holotype.</i> &amp;male;, Thailand: Narathiwat Province: Wiang District, Hala Bala Wildlife Sanctuary, Sirinthorn waterfall, 200 m, evergreen rainforest, 8 January 1999, leg. P.J. Schwendinger (MHNG, PJS-5). <i>Paratypes.</i> Data as holotype, 1&amp;male;, 2&amp;female; (MHNG, PJS-5). Malaysia: Pahang State: Charas Hill, 3 km north of Panching, 60 m, rainforest remnants at foot of limestone hill, 3 June 2004, leg. P.J. Schwendinger, 2&amp;male;, 5&amp;female; (MHNG, MAL-04 <i>/</i> 08); from type locality, 9 July 2001, 5&amp;male;, 2&amp;female; (MHNG, SIM-01 <i>/</i> 12). Fraser Hill, Maxwell Trail, 1350 m, evergreen hill forest, 12–16 May 2004, leg. P.J. Schwendinger, 7&amp;male;, 5&amp;female; (MHNG, MAL-04 <i>/</i> 01). <i>Etymology</i> The specific epithet, a nominative form of an adjective, is derived from Greek (βρα <i>Χιων</i> (brachion) = arm), and refers to the shape of the insemination ducts of the internal female genitalia. <i>Description</i> <i>Male</i> (holotype). Total length 5.08; prosoma 2.44 long, 1.66 wide; opisthosoma 2.64 long, 1.32 wide. Leg formula: 1423; I 11.38 (2.62, 1.04, 3.54, 2.46, 1.72); II 9.04 (2.06, 1.04, 2.76, 1.96, 1.22); III 7.52 (1.70, 0.94, 2.14, 1.66, 1.08); IV 10.90 (2.68, 1.04, 3.06, 2.66, 1.46). Spination: Leg I: Femora p1-1-1; tibiae p10 r10; metatarsi p6 r5. Leg II: Tibiae p10 r8; metatarsi p5 r4. Carapace dark chestnut-brown; submarginal lobes slightly elevated, their apices triangular, sharply pointed (Figure 1 E). Sternum dark chestnut-brown. Legs hairless, bi-coloured: Tibiae, metatarsi and tarsi yellowish, other segments orange-brown. Opisthosoma elongate-ovoid. Dorsal scutum covering almost entire opisthosoma length. Palp (Figure 7 A–C): RTA triangular, its apex blunt, anterior margin with colourless and transparent lamina. DTA reduced, represented by sclerotized ridge. Tegulum more or less spherical, slightly excavated posteriorly. Conductor elongated, spiral, its apex blunt. Embolic base indistinct. <i>Female</i> (paratype, MHNG, MAL-04/08). Total length 5.90; prosoma 2.66 long, 1.64 wide; opisthosoma 3.24 long, 1.66 wide. Leg formula: 1423; I 12.08 (2.68, 1.04, 3.98, 2.66, 1.72); II 9.24 (2.12, 1.04, 3.08, 1.74, 1.26); III 8.06 (1.74, 0.96, 2.28, 1.86, 1.22); IV 11.52 (2.68, 1.06, 3.26, 2.84, 1.68). Spination: Leg I: Femora p1-1-1; tibiae p10 r10; metatarsi p6 r6. Leg II: Tibiae p10 r9; metatarsi p6 r6. General appearance as in male except submarginal lobes on carapace broader at base, less elevated, their apices reduced; dorsum of opisthosoma dark greenish. Genitalia (Figure 7 D,E): Epigyne with semi-circular copulatory orifices situated anteriorly. Insemination ducts elongated, descending posteriorly then abruptly ascending anteriorly, connected to anterior lateral portion of spermathecae. Secretory ampullae spherical, originating subproximally on insemination ducts. Spermathecae elliptic, widest medially, provided with subapical glandular pore on inner surface. Fertilization ducts truncated. <i>Distribution</i> Southern tip of Thailand and Malay Peninsula (Figure 18).
