Diagnosis. Mallinella advena sp. nov. is recognized by the broad anterior flange on the conductor ( Fig. 380 View FIGURES 380–386. 380–382 ) and by the duct of spermathecae not coiled.

Etymology. The specific epithet ( advena = new comer, foreigner), a noun in apposition, refers to the relationships of this species to members of the decorata -group.

Description. Male (holotype). Total length 6.60; prosoma 3.30 long, 2.31 wide. Eye sizes and interdistances: AME 0.28, ALE 0.18, PME 0.18, PLE 0.18, AME–AME 0.08, AME–ALE 0.16, PME–PME 0.18, PME–PLE 0.38; MOQ: 0.44 long, 0.54 anterior width, 0.51 posterior width. Leg measurements: I 9.07 (2.47, 3.30, 1.89, 1.40), II 7.76 (2.06, 2.80, 1.66, 1.22), III 6.56 (1.88, 1.86, 1.66, 1.15), IV 10.06 (2.64, 3.12, 2.80, 1.48).

Coloration ( Figs 371–372 View FIGURES 371–374. 371–372 ). Carapace uniform dark chestnut-brown, integument moderately granulated. Coxae whitish; femora yellowish proximally, brown distally; patellae, tibiae, metatarsi and tarsi yellowish, slightly darker distally. Opisthosoma dark sepia. Dorsum with greatly reduced dorsal pattern: first and second pairs almost indistinct; third and fourth pairs by remnant of pale spots. Dorsal scutum brown, coriaceous, lanceolate.

Palp ( Figs 381–382 View FIGURES 380–386. 380–382 ). RTA blunt, gradually tapered towards apex, prolaterally bent in ventral view. Cymbial fold narrow, occupying less than half-length of cymbium. Conductor provided with a sharply pointed apex, a broad anterior flange and a truncate dorsal process. TA with bifid apical process; apico-prolateral fold convex; baso-prolateral fold triangular, bluntly pointed in promesal view. Tegular spine represented by low elevated ridge. Embolic base subtriangular, strongly excavated baso-retrolaterally; membranous area irregular thin band. Embolus thick and broad basally, abruptly narrowed at half its length, provided with large, triangular, dorso-prolateral flange and much smaller subapical flange, apex blunt.

Female (paratype). Total length 6.12; prosoma 3.06 long, 2.15 wide. Eye sizes and interdistances: AME 0.26, ALE 0.16, PME 0.16, PLE 0.18, AME–AME 0.18, AME–ALE 0.14, PME–PME 0.18, PME–PLE 0.36; MOQ: 0.42 long, 0.53 anterior width, 0.50 posterior width.

Coloration ( Figs 373–374 View FIGURES 371–374. 371–372 ). Carapace uniform orange-brown. Legs bi-colored: coxae, trochanters and proximal part of femora almost whitish; distal part of femora, tibiae and metatarsi on anterior legs yellowish, on posterior legs pale brown. Opisthosoma dark sepia, background mottled with numerous minute pale spots. Dorsal pattern: first to fifth pairs each represented by paired pale patches; third and fourth pairs distinctly smaller; from fifth pair onwards forming a series of transverse bands.

Genitalia ( Figs 377 View FIGURES 375–379. 375–376, 378 , 383–386 View FIGURES 380–386. 380–382 ). Epigynal plate lenticular, protruding over epigastric furrow, lateral lobes distinctly elevated. Lateral borders retracted, becoming part of rebordered epigastric furrow. Internal genitalia with moderately long insemination ducts. Spermathecae more or less cylindrical in anterior view, strongly bent posteriorly, apex blunt, with broad internal duct.

Natural history. Mallinella advena sp. nov. inhabits lowland dry dipterocarp forests.

Distribution. Known only from the type locality in northeastern Thailand.
