description: <i>Teutamus seculatus</i> sp. nov. (Figures 1 D, 13 A–E) <i>Diagnosis</i> Males of <i>T. seculatus</i> sp. nov. resemble those of <i>T. brachiatus</i> sp. nov. in having an elongate conductor but can be distinguished by the presence of a minute accessory apophysis (Figure 13 A,B); females can be recognized by the elliptic spermathecae provided with short and tortuous anterior insemination ducts (Figure 13 E). <i>Type material</i> <i>Holotype.</i> &amp;male;, Indonesia: Ligga Island: waterfall <i>c</i>. 7 km north of Dalik, 60 m, rainforest along stream, 13–15 July 2001, leg. P.J. Schwendinger (MHNG, SIM-01 <i>/</i> 03). <i>Paratypes.</i> Malaysia: Johor State: Mt Ophir, Puteri Waterfall, 80–130 m, rainforest near stream, 21 May 2004, leg. P.J. Schwendinger, 5&amp;male;, 3&amp;female; (MHNG, MAL-04 <i>/</i> 03). <i>Etymology</i> The specific epithet is a nominative form of an adjective (Latin: <i>secula</i> = sickle), and refers to the sickle-shaped conductor on the male palp. <i>Description</i> <i>Male</i> (holotype). Total length 4.82; prosoma 2.30 long, 1.52 wide; opisthosoma 2.52 long, 1.22 wide. Leg formula: 1423; I 10.58 (2.40, 0.90, 3.40, 2.32, 1.56); II 8.26 (1.92, 0.90, 2.60, 1.80, 1.04); III 6.88 (1.54, 0.82, 2.02, 1.50, 1.00); IV 10.24 (2.54, 1.00, 2.88, 2.46, 1.36). Spination: Leg I: Femora p1-1-1; tibiae p9 r9; metatarsi p5 r5. Leg II: Tibiae p9 r8; metatarsi p5 r4. Carapace dark reddish brown; submarginal lobes triangular, their apices bluntly pointed. Sternum dark reddish brown. Legs hairless, bi-coloured: Coxae, metatarsi and tarsi yellowish, other segments orangebrown. Opisthosoma elongate-ovoid. Dorsal scutum covering two-thirds of length of opisthosoma. Palp (Figure 13 A–C). RTA digitiform, strongly excavated anteriorly, its apex blunt, anterior margin with colourless and transparent. DTA short and stout. Tegulum elongate-ovoid, with field of lightly sclerotized area on baso-retrolateral side. Conductor elongated, gradually narrowing towards sharply pointed apex. Embolic base almost indistinct. Accessory tegular apophysis minute, triangular, situated close to conductor. <i>Female</i> (paratype, MHNG, MAL-04/03). Total length 5.58; prosoma 2.48 long, 1.50 wide; opisthosoma 3.10 long, 1.52 wide. Leg formula: 1423; I 11.52 (2.46, 0.90, 3.84, 2.50, 1.52); II 8.52 (1.96, 0.90, 2.96, 1.60, 1.10); III 7.26 (1.60, 0.80, 2.12, 1.70, 1.04); IV 10.72 (2.50, 0.90, 3.12, 2.70, 1.50). Spination: Leg I: Femora p1-1-1; tibiae p10 r10; metatarsi p6 r6. Leg II: Tibiae p9 r9; metatarsi p5 r5. General appearance as in male except submarginal lobes on carapace distinctly broader, their apices blunt; dorsum of opisthosoma dark greenish. Genitalia (Figure 13 D,E): Epigyne with two large, circular copulatory orifices situated anteriorly. Insemination ducts descending mid-longitudinally then abruptly ascending anteriorly, connected to apical portion of spermathecae. Secretory ampullae digitiform, originating terminally on insemination ducts. Spermathecae elliptic, gradually narrowing anteriorly, provided with sub-apical glandular pore on inner surface and median pore on dorsal surface. Fertilization ducts lanceolated. <i>Distribution</i> The southern tip of Malay Peninsula and Ligga Island of Indonesia (Figure 18). The following species described below are based on single sex. Nevertheless, it has been possible to circumscribe all taxa with reasonable clarity on their species boundaries.
