Diagnosis. Males of this new species can be distinguished from those of M. decorata by the embolus being entirely filiform ( Fig. 341 View FIGURES 341–346. 341, 343 ) rather than proximally broad as in M. decorata . Females can be separated by the epigynal plate with less elevated lateral ridges ( Fig. 328 View FIGURES 327–331. 327–329 ) and by the much longer spermathecae ( Fig. 329 View FIGURES 327–331. 327–329 ).

Etymology. The specific epithet is a latinized adjective (filicatus = ornamented with fern) and refers to the thread-like embolus on the male palp.

Description. Male (holotype). Total length 7.10; prosoma 3.49 long, 2.86 wide. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.06, PLE 0.06, AME–AME 0.06, AME–ALE 0.10, PME–PME 0.10, PME–PLE 0.56; MOQ: 0.28 long, 0.22 anterior width, 0.22 posterior width. Leg measurements: I 9.64 (2.65, 2.96, 2.12, 1.90), II 9.43 (2.43, 2.96, 2.33, 1.69), III 9.32 (2.54, 2.86, 2.43, 1.48), IV 11.36 (2.65, 3.71, 3.49, 1.50).

Coloration ( Fig. 306 View FIGURES 306–309. 306, 308–309 ). Carapace dark chestnut-brown, sparsely covered with white pubescence on cephalic area. Sternum brown. Chelicerae dark brown. Coxae white; femora dark greenish brown; patellae proximally greenish brown, distally pale yellowish; metatarsi and tarsi yellowish, distally darker. Opisthosoma dark brown, clothed with fine pubescence. Dorsal pattern: first pair represented by small, oblong pale spots; second pair by disconnected median band extending anteriorly; third and fourth pairs by two pairs of broken bands; from fifth pair onwards by a series of transverse median bands fusing with additional pair of pale spots. Dorsal scutum coriaceous, broadest anteriorly, lateral margin undulated, extending to half opisthosomal length.

Palp ( Figs 341, 343 View FIGURES 341–346. 341, 343 ). RTA digitiform, broad at base, gradually tapered anteriorly, apex blunt. Cymbial fold broad basally, reaching approximately 3/4 length of cymbium. Conductor with sharply pointed apex; dorsal process digitiform, apex blunt; basal sclerite subtriangular, extending anteriorly. TA terminally with diverging bifid apical process, mesal branch slender, sharply pointed, lateral one slightly shorter; apico-prolateral and baso-prolateral folds strongly pronounced, subtriangular, directed mesad. Tegular spine sharply pointed. Embolic base triangular, anterior margin slightly excavated medially; membranous area situated on prolateral side. Embolus filiform, elongated, originating at 90°.

Female (paratype, MHNG). Total length 8.48; prosoma 4.02 long, 2.65 wide. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.08, PLE 0.08, AME–AME 0.06, AME–ALE 0.12, PME–PME 0.08, PME–PLE 0.22; MOQ: 0.30 long, 0.38 anterior width, 0.24 posterior width. Leg measurements: I 8.79 (2.54, 2.65, 2.22, 1.37), II 9.25 (2.50, 2.91, 2.22, 1.61), III 8.84 (2.56, 2.81, 2.07, 1.37), IV 9.47 (2.65, 2.73, 2.54, 1.54).

Coloration ( Fig. 307 View FIGURES 306–309. 306, 308–309 ). General appearance similar to males but carapace less domed, covered with fewer iridescent pubescence. Dorsal scutum absent.

Genitalia ( Figs 327–329 View FIGURES 327–331. 327–329 , 344–346 View FIGURES 341–346. 341, 343 ). Epigynal plate lenticular, protruding over epigastric furrow, with two slightly elevated lateral ridges and shallow anterior median incision. Lateral border retracted. Epigastric furrow strongly rebordered. Spermathecae elongated, tubular, strongly bent posteriorly, apex rounded, internal duct with 5 apical coils.

Natural history. Mallinella filicata sp. nov. inhabits dry dipterocarp forests and semi-evergreen rainforests.

Distribution. Northeastern and eastern Thailand.
