description: <i>Mallinella bidenticulata</i> sp. nov. (Figs 208–209, 226, 228, 236, 256–264) Material examined. <b>Holotype:</b> &amp;male;, <b>southern THAILAND, <i>Phang Nga Province</i>:</b> Khao Sok NP, 30 km east of Takua Pa (8º55'N, 98º36'E), 50 m, lowland evergreen rainforest, 24 March 2006, leg. P. Dankittipakul (MHNG). <b>Paratypes:</b> 4&amp;male;, same data as holotype (MHNG, TNHM); 1&amp;female;, ibidem, 21–26 December 1997, Winkler extraction in secondary moist forest with primary spots, leg. A. Schulz (MHNG, AS–T–1). <b>THAILAND</b> <b>,</b> <b> <i>Ranong Province</i>:</b> 1&amp;female;, Kapoe District, Khlong Nakha Wildlife Sanctuary, 30 m, 29 January 1991, leg. P.J. Schwendinger (MHNG). <b>Diagnosis.</b> Males of <i>M. bidenticulata</i> sp. nov. are recognized by the subterminal spike on a bifid embolus and the strongly modified embolic extremities (Fig. 260). Males can be distinguished from those of the closely related <i>M. rostrata</i> sp. nov. by the mesal part of TA provided with two denticles. Females can be recognized by the strongly elevated epigynal plate with deep anterior median incision (Fig. 228); distinguished from those of <i>M. belladonna</i> sp. nov. by the absence of an anterolateral swelling of the spermathecae. <b>Etymology.</b> The specific epithet refers to the TA of male palp which carries two denticles. <b>Description. Male</b> (holotype). Total length 8.37; prosoma 4.12 long, 3.37 wide. Eye sizes and interdistances: AME 0.24, ALE 0.20, PME 0.20, PLE 0.21, AME–AME 0.12, AME–ALE 0.22, PME–PME 0.18, PME–PLE 0.40; MOQ: 0.54 long, 0.52 anterior width, 0.50 posterior width. Leg measurements: I 11.37 (3.12, 3.50, 2.50, 2.25), II 11.25 (2.87, 3.50, 2.75, 2.00), III 11.25 (3.0, 3.37, 3.00, 1.87), IV 13.4 (3.12, 4.37, 4.12, 1.77). <i>Coloration</i> (Fig. 208). Carapace dark chestnut-brown. Sternum and chelicerae brown. Legs yellowish, except for distal part of femora yellowish brown. Dorsum of opisthosoma dark sepia. Dorsal pattern: first pair represented by irregular pale spots; second pair by broad, disconnected transverse band; third to fifth pairs forming medially connected median bands. Dorsal scutum indistinct. <i>Palp</i> (Figs 256–260). Retrolateral margin of palpal tibia moderately elevated, apex bluntly pointed. RTA digitiform, broad at base, gradually tapered towards blunt apex. TA rostrated; apico-prolateral process bifid, directed posteromesad; meso-prolateral tooth triangular, apically blunt, situated anterior to smaller meso-retrolateral tooth; baso-prolateral ridge sharply pointed, directed anteriad. Tegular spine minute, terminally blunt. Embolic base originating at 270°. Embolus broad, branching proximally; mesal ramus thinner than lateral one; apex of lateral ramus provided with semi-transparent subterminal flanges and slender spike. <b>Female</b> (paratype). Total length 9.71; prosoma 4.78 long, 3.91 wide. Eye sizes and interdistances: AME 0.30, ALE 0.26, PME 0.20, PLE 0.24, AME–AME 0.12, AME–ALE 0.22, PME–PME 0.20, PME–PLE 0.44; MOQ: 0.58 long, 0.56 anterior width, 0.52 posterior width. Leg measurements: I 12.03 (3.48, 3.62, 3.04, 1.88), II 10.68 (3.42, 3.62, 2.17, 1.46), III 11.77 (3.36, 3.68, 2.84, 1.88), IV 12.96 (3.62, 3.74, 3.48, 2.11). <i>Coloration</i> (Fig. 209). Carapace reddish brown. Sternum and chelicerae brown. Legs yellowish. Dorsum of opisthosoma sepia, mottled with numerous minute pale spots. Dorsal pattern: first pair represented by pale, oblong spots; second pair by slightly broad, medially disconnected band; third to fifth pairs by irregular chevrons. <i>Genitalia</i> (Figs 228, 236, 261–264). Epigynal plate strongly elevated, with deep anterior median incision and straight posterior margin. Lateral border terminally bluntly pointed. Spermathecae enlarged, constricted mesolaterally, rounded apically. <b>Natural history.</b> <i>Mallinella bidenticulata</i> sp. nov. inhabits secondary and semi-evergreen lowland rainforest. <b>Distribution.</b> Southern Thailand.
