description: Mallinella atromarginata sp. nov.   
(Figs 106–107, 110–111, 114, 139–146)  
 Material examined. Holotype: ♂,  THAILAND, Chaiyaphum Province:  Tard Tone NP, dry dipterocarp forest, 250 m, 15 August 2006, leg. P. Dankittipakul (MHNG, PDC –7451). Paratypes: 1♂, 1♀, same data as holotype (MHNG, PDC –7451).  THAILAND, Chaiyaphum Province  : 3♂, from the type locality, 15 September 2006 (THNM, PDC-7451); 1♀, ibidem, 15 October 2006 (TNHM); 1♀, ibidem, 6 July 2006 (MHNG). All leg. P. Dankittipakul.   
 Diagnosis. Mallinella atromarginata sp. nov. can be recognized by the dark, chestnut-brown marginal color of the carapace (Figs 106–107). The male palpal structure is similar to that of M. tuberculata sp. nov. in possessing an oblique mesal ridge and a minute mesal tooth on the TA but can be distinguished by a slender but longer apico-prolateral process (Figs 139 cf. 130) and by a distinctly broader mesal ridge of the embolus. It is difficult to distinguish the females of these two species with any certainty because the close resemblance of the epigynal plate and their internal genitalia. Without the presence of a conspecific male, a correct identification cannot be made with certainty.   
 Etymology. The specific epithet, an adjective, is derived from a combination of Latin words (ater = black; marginatus = with a border) meaning ‘dark margins’ and refers to distinctive color pattern on the carapace.   
 Description. Male  (holotype). Total length 7.50; prosoma 3.74 long, 2.91 wide; opisthosoma 3.76 long, 2.86 wide. Eye sizes and interdistances: AME 0.20, ALE 0.16, PME 0.16, PLE 0.16, AME–AME 0.12, AME–ALE 0.14, PME–PME 0.15, PME–PLE 0.28; MOQ: 0.52 long, 0.38 anterior width, 0.40 posterior width. Leg measurements: I 10.37 (2.86, 3.19, 2.31, 2.01), II 9.96 (2.57, 3.13, 2.46, 1.79), III 10.08 (2.68, 30.2, 2.68, 1.68), IV 12.00 (2.80, 3.92, 3.69, 1.59).   
 Coloration (Fig. 106). Center of carapace orange-brown, margin dark chestnut-brown. Chelicerae dark brown. Sternum yellowish. Legs yellowish, proximal part of each segment paler than distal part. Dorsum of opisthosoma sepia. Dorsal pattern: first pair represented by paired round spots; second pair by narrow, transverse band; from third pair onwards fused, forming pale folium-like patch. Dorsal scutum longitudinal, edge clearly defined.   
 Palp (Figs 139–142). RTA rectangular in lateral view, abruptly tapered anteriorly at half its length; dorsal tubercle short, subtriangular, apex bluntly pointed. Cymbial fold approximately 1/3 length of cymbium. Tegular spine triangular, sharply pointed. TA terminally with very short and blunt apico-prolateral fold; apico-prolateral process slender, elongated, apex sharply pointed; apico-retrolateral arm triangular in ventral view; mesal ridge running obliquely, with two triangular denticles; mesal tooth triangular, situated posterior to mesal ridge. Embolus originating at 270°, with longitudinal groove over entire length; mesal ridge translucent, dilated apically; apex of lateral ridge terminally abruptly bent ectad.   
 Female (paratype, MHNG PDC–7451). Total length 8.36; prosoma 3.96 long, 2.53 wide; opisthosoma 4.40 long, 2.75 wide. Eye sizes and interdistances: AME 0.18, ALE 0.15, PME 0.15, PLE 0.15, AME–AME 0.14, AME–ALE 0.28, PME–PME 0.16, PME–PLE 0.34; MOQ: 0.50 long, 0.40 anterior width, 0.50 posterior width. Leg measurements: I 9.29 (2.68, 2.80, 2.35, 1.45), II 8.25 (2.64, 2.80, 1.68, 1.13), III 9.34 (2.71, 2.97, 2.19, 1.45), IV 10.01 (2.80, 2.88, 2.68, 1.63).   
 Coloration (Fig. 107). Center and posterior part of carapace orange-brown, anterior and lateral margin dark brown. Chelicerae dark brown. Sternum yellowish. Legs yellowish. Dorsum of opisthosoma dark sepia. Dorsal pattern: as in male but second pair represented by paired triangular patches. Dorsal scutum coriaceous, narrowed, edge vaguely defined.   
 Genitalia (Figs 114, 143–146). Epigynal plate V-shaped, with broad anterior median incision. Internal genitalia with digitiform spermathecae, their apex blunt, lateral margin more or less straight in anterior view.   
 Natural history. The type specimens were collected in dry dipterocarp forests by means of pitfall traps at relatively low altitude.   
 Distribution. Known only from the type locality in northeastern Thailand (Chaiyaphum Province).
