( Figures 1 D, 13 A–E) Diagnosis Males of T. seculatus sp. nov. resemble those of T. brachiatus 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).

Etymology The specific epithet is a nominative form of an adjective (Latin: secula = sickle), and refers to the sickle-shaped conductor on the male palp. Description Male (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. Female (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. Distribution 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.
