Material examined. Holotype: ♂, southern THAILAND, Phang Nga Province: 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) GoogleMaps . Paratypes: 4♂, same data as holotype ( MHNG, TNHM) GoogleMaps ; 1♀, ibidem, 21–26 December 1997, Winkler extraction in secondary moist forest with primary spots, leg. A. Schulz ( MHNG, AS–T–1). THAILAND , Ranong Province: 1♀, Kapoe District, Khlong Nakha Wildlife Sanctuary , 30 m, 29 January 1991, leg. P.J. Schwendinger ( MHNG) .

Diagnosis. Males of M. bidenticulata sp. nov. are recognized by the subterminal spike on a bifid embolus and the strongly modified embolic extremities ( Fig. 260 View FIGURES 256–264. 256–260 ). Males can be distinguished from those of the closely related M. rostrata 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 View FIGURES 227–234. 227 ); distinguished from those of M. belladonna sp. nov. by the absence of an anterolateral swelling of the spermathecae.

Etymology. The specific epithet refers to the TA of male palp which carries two denticles.

Description. Male (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).

Coloration ( Fig. 208 View FIGURES 208–211. 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.

Palp ( Figs 256–260 View FIGURES 256–264. 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.

Female (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).

Coloration ( Fig. 209 View FIGURES 208–211. 208 ). 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.

Genitalia ( Figs 228 View FIGURES 227–234. 227 , 236 View FIGURES 235–242. 235 , 261–264 View FIGURES 256–264. 256–260 ). Epigynal plate strongly elevated, with deep anterior median incision and straight posterior margin. Lateral border terminally bluntly pointed. Spermathecae enlarged, constricted mesolaterally, rounded apically.

Natural history. Mallinella bidenticulata sp. nov. inhabits secondary and semi-evergreen lowland rainforest.
