Teutamus lioneli sp. nov.

( Figures 1 F, 2 G, 9 A–E)

Diagnosis

Males of T. lioneli sp. nov. can be recognized by the presence of a circular pit on retrolateral side of the tegulum ( Figure 9 A–C), the relatively small RTA and the triangular, sharply pointed submarginal lobes on the carapace ( Figures 1 D, 2 G); females resemble those of T. jambiensis but can be distinguished by the curved insemination ducts connecting to anterior portion of the reniform spermathecae instead of middle portion ( Figure 9 E).

Etymology

The specific epithet, an eponymous patronym (genitive case), is established in honour of Dr Lionel Monod (MHNG) who collected many spider specimens from Tioman Island.

Leg formula: 1423; I 9.86 (2.30, 0.90, 3.32, 2.18, 1.16); II 7.96 (1.80, 0.88, 2.54, 1.72, 1.02); III 6.70 (1.44, 0.90, 1.96, 1.56, 0.84); IV 9.90 (2.40, 0.92, 2.84, 2.46, 1.28). Spination: Leg I: Femora p1-1-1; tibiae p8 r8; metatarsi p4 r4. Leg II: Tibiae p7 r7; metatarsi p4 r3. Carapace dark reddish brown; submarginal lobes triangular, apices sharply pointed; integument not punctate. Sternum dark reddish brown. Legs hirsute, bi-coloured: Coxae to femora reddish brown, other segments yellowish, with dark greenish annulation on distal portion of femora, patellae and tibiae. Opisthosoma elongate-ovoid. Dorsal scutum covering two-thirds of length of opisthosoma.

Palp ( Figure 9 A–C): RTA triangular, minute, its apex bluntly pointed, entirely sclerotized. DTA digitiform. Tegulum ovoid, protruding posteriorly, slightly excavated on pro-apical side, provided with deep circular pit on meso-retrolateral side. Conductor triangular, its apex sharply pointed. Embolic base clearly visible.

Female (paratype, MHNG, AS-05/08). Total length 5.54; prosoma 2.48 long, 1.50 wide; opisthosoma 3.06 long, 1.44 wide. Leg formula: 1423; I 10.88 (2.42, 0.90, 3.72, 2.40, 1.44); II 8.34 (2.00, 0.90, 2.88, 1.52, 1.04); III 710 (1.52, 0.88, 2.02, 1.66, 1.02); IV 10.32 (2.40, 0.92, 3.00, 2.62, 1.38). Spination: Leg I: Femora p1-1-1; tibiae p9 r9; metatarsi p5 r5. Leg II: Tibiae p9 r8; metatarsi p5 r4. General appearance as in male except submarginal lobes on carapace broader at base, their apices bluntly pointed; legs reddish brown, uniform in colour; dorsum of opisthosoma dark greenish.

Genitalia ( Figure 9 E,F): Epigyne with circular copulatory orifices situated anteriorly. Insemination ducts curved, connected to apical portion of spermathecae. Secretory ampullae spherical, originating subproximally on insemination ducts. Spermathecae reniform, widely separated, provided with glandular pore situated laterally on dorsal surface. Fertilization ducts lanceolated.

Distribution

Known only from Tioman Island, Malaysia ( Figure 18).
