( Figs 215 View FIGURES 212–215. 212 , 231 View FIGURES 227–234. 227 , 239 View FIGURES 235–242. 235 , 250–255 View FIGURES 250–255. 250–253 )
Material examined. Holotype: ♂, THAILAND, Song Khla Province : Khao Kor-Hong, 15 October 2005, leg. B. Phongsee ( MHNG) . Paratypes: THAILAND, Nakhon Sri Thammarat Province: 2♀, 3 juveniles, Tha Sala District, Khao Nan NP, soil sample, 14–15 July 2005, leg. P. Dankittipakul ( MHNG) .
Diagnosis. Males are similar to those of M. bidenticulata sp. nov. in having a bifid apical process, a triangular meso-prolateral ridge, and a basal ridge on the TA of the male palp ( Fig. 250 View FIGURES 250–255. 250–253 ); in M. bidenticulata sp. nov. the mesal modification is represented by two denticles ( Fig. 256 View FIGURES 256–264. 256–260 ). Females can be separated from all other members of the hilaris -group by the presence of an anterior median hump on the epigynal plate ( Fig. 231 View FIGURES 227–234. 227 ).
Etymology. The specific epithet is derived from Latin (rostratus, –a, –um = with a beak) and refers to the shape of the TA.
Description. Male (holotype). Total length 8.71; prosoma 4.29 long, 3.51 wide. Eye sizes and interdistances: AME 0.18, ALE 0.15, PME 0.15, PLE 0.15, AME–AME 0.08, AME–ALE 0.20, PME–PME 0.12, PME–PLE 0.26; MOQ: 0.50 long, 0.46 anterior width, 0.42 posterior width. Leg measurements: I 15.47 (3.51, 4.29, 3.25, 4.42), II 11.57 (2.99, 3.64, 2.86, 2.00), III 11.70 (3.12, 3.51, 3.12, 1.95), IV 13.90 (3.25, 4.55, 4.29, 1.84).
Coloration. Carapace dark chestnut-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish. Dorsum of opisthosoma sepia, mottled with numerous pale spots. Dorsal pattern: first and second pairs represented by paired pale spots, first pair oblong, second pair short transverse bands; third to fifth pairs forming a series of transverse bands. Dorsal scutum indistinct.
Palp ( Figs 250–253 View FIGURES 250–255. 250–253 ). Retrolateral margin of palpal tibia well-developed, subtriangular, apex bluntly pointed. RTA digitiform, short and broad, apically rounded. Tegular spine minute, terminally blunt. TA rostrated; apico-prolateral process bifid, elongated, directed mesad; meso-prolateral ridge triangular, margin curved anteriorly; postero-retrolateral ridge triangular, directed ventrad in prolateral view; baso-prolateral ridge visible only in ventral view. Embolic base originating at 270°. Embolus broken off.
Female (paratype). Total length 12; prosoma 5.70 long, 3.75 wide. Eye sizes and interdistances: AME 0.32, ALE 0.26, PME 0.20, PLE 0.25, AME–AME 0.12, AME–ALE 0.22, PME–PME 0.20, PME–PLE 0.46; MOQ: 0.78 long, 0.74 anterior width, 0.72 posterior width. Leg measurements: I 12.45 (3.60, 3.75, 30.15, 1.95), II 11.05 (3.54, 3.75, 2.25, 1.51), III 12.18 (3.48, 3.81, 2.94, 1.95), IV 13.41 (3.75, 3.87, 3.60, 2.19).
Coloration ( Fig. 215 View FIGURES 212–215. 212 ). Carapace brown, radiating striae orange-brown. Sternum and chelicerae brown. Legs yellowish. Dorsum of opisthosoma sepia, mottled with numerous minute pale spots. Dorsal pattern: first pair represented by small round spots; second pair by paired curved bands extending laterally; third to fifth pairs by chevrons.
Genitalia ( Figs 231 View FIGURES 227–234. 227 , 239 View FIGURES 235–242. 235 , 254–255 View FIGURES 250–255. 250–253 ). Epigynal plate strongly rebordered, provided with median hump, posterior margin excavated medially. Lateral borders retracted. Insemination ducts long, clearly separated from heavily sclerotized spermathecae. Basal part of spermathecae cylindrical, apical part spherical.
Natural history. Mallinella rostrata sp. nov. inhabits secondary evergreen forest.
Distribution. Southern Thailand.
