( Figures 1 View Figure 1 E, 2 F, 7 A–F)
Diagnosis
Males of T. brachiatus sp. nov. closely resemble those of T. fertilis in having a more or less spherical tegulum but can be distinguished by the more elongate conductor ( Figure 7 View Figure 7 A); females can be recognized by the abruptly bent insemination duct at its half length ( Figure 7 View Figure 7 E,F).
Type material
Holotype. ♂, 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) .
Paratypes. Data as holotype, 1♂, 2♀ ( 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♂, 5♀ ( MHNG, MAL-04 / 08) ; from type locality, 9 July 2001, 5♂, 2♀ ( MHNG, SIM-01 / 12) . Fraser Hill, Maxwell Trail , 1350 m, evergreen hill forest , 12–16 May 2004, leg. P.J. Schwendinger, 7♂, 5♀ ( MHNG, MAL-04 / 01) .
Etymology
The specific epithet, a nominative form of an adjective, is derived from Greek (βρα Χιων (brachion) = arm), and refers to the shape of the insemination ducts of the internal female genitalia.
Description
Male (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 View 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 View 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.
Female (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 View 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.
