description: <i>Teutamus serrulatus</i> sp. nov. (Figures 3 A,B,G, 6 A–F) <i>Diagnosis</i> Males of <i>T. serrulatus</i> sp. nov. can be easily distinguished by a row of serrated denticles on baso-prolateral side of the conductor (Figure 6 B,D); females can be recognized by the large, circular epigynal atrium (Figures 3 A, 6E) and the simple internal genitalia without clear boundary between insemination ducts and spermathecae (Figure 6 F). <i>Type material</i> <i>Holotype.</i> &amp;male;, Malaysia: Johor State: Mt Arong, 20 m, rainforest 15 km north of Mersing, 29 May 2004, leg. P.J. Schwendinger (MHNG, MAL-04 <i>/</i> 06). <i>Paratypes.</i> Data as holotype, 1&amp;male;, 1&amp;female; (MHNG, MAL-04 <i>/</i> 06). Pahang State: Cameron Highlands, 1600 m, trail 14, Mt Mentiga, sifting at the summit, 23 March 1993, leg. I. Löbl and F. Calame, 1&amp;female; (MHNG, WM-93 <i>/</i> 16a). <i>Etymology</i> The specific epithet is a nominative form of an adjective, derived from Latin (<i>serrulatus</i>, - <i>a</i>, - <i>um</i> = with small teeth), referring to the serrated prolateral margin of the conductor. <i>Description</i> <i>Male</i> (holotype). Total length 4.84; prosoma 2.32 long, 1.52 wide; opisthosoma 2.52 long, 1.16 wide. Leg formula: 1423; I 10.80 (2.46, 0.96, 3.46, 2.34, 1.58); II 8.52 (1.96, 0.94, 2.66, 1.84, 1.12); III 7.00 (1.60, 0.86, 2.06, 1.54, 0.94); IV 10.38 (2.56, 0.96, 2.96, 2.54, 1.36). Spination: Leg I: Femora p1-1-1; tibiae p9 r9; metatarsi p5 r5. Leg II: Tibiae p8 r8; metatarsi p5 r4. Carapace reddish brown; submarginal lobes triangular, their apices globular. Sternum dark reddish brown. Legs hairless, bi-coloured: Femora to tarsi yellowish brown, other segments orange-brown. Opisthosoma elongate-ovoid. Dorsal scutum reddish brown, covering two-thirds of length of opisthosoma. Palp (Figure 6 A–D): RTA digitiform in ventral view, strongly excavated medially, its apex blunt. DTA digitiform, weakly sclerotized, provided with small, elevated lump at base. Tegulum protruding apico-retrolaterally, strongly excavated on baso-retrolateral side, with colourless and transparent area. Conductor triangular in ventral view, columnar with sharply pointed apex in prolateral view, its prolateral margin strongly serrated. Embolic base clearly visible. <i>Female</i> (paratype, MHNG, MAL-04/06). Total length 5.68; prosoma 2.52 long, 1.54 wide; opisthosoma 3.16 long, 1.56 wide. Leg formula: 1423; I 11.44 (2.56, 0.94, 3.88, 2.54, 1.52); II 8.72 (2.02, 0.94, 2.96, 1.64, 1.16); III 7.54 (1.66, 0.86, 2.14, 1.76, 1.12); IV 10.86 (2.54, 0.92, 3.14, 2.72, 1.54). Spination: Leg I: Femora p1-1-1; tibiae p10 r10; metatarsi p6 r6. Leg II: Tibiae p10 r9; metatarsi p5 r5. General appearance as in male except legs orange-brown, uniform in colour; dorsum of opisthosoma greenish, provided with a series of pale chevrons. Genitalia (Figures 3 A,B,G, 6 E,F): Epigyne with large, circular atrium filled with dark, hardening secretion. Copulatory orifices elongate-ovoid, situated anteriorly on epigynal atrium. Boundary between insemination ducts and spermathecae indistinct. Secretory ampullae digitiform, originating on inner surface of insemination ducts. Spermathecae elongated, with glandular pore situated posteriorly on dorsal surface. Fertilization ducts lanceolated. <i>Distribution</i> Known from localities on the Malay Peninsula (Figure 18).
