description: Mallinella concava sp. nov.   
(Figs 608, 622, 633, 664–671)  
 Material examined. Holotype: ♂,  INDONESIA, Sumatra,   Jambi Province:  Mt. Kerinci, footpath to summit, west of Kersik Tua, 2,160 m, evergreen hill forest, 17–18 February 2000, leg. P.J. Schwendinger (MHNG, Sum –00/ 13). Paratype: 1♀, same data as holotype (MHNG, Sum –00/13).   
 Diagnosis. The male of M. concava sp. nov. can be recognized by the concave anterior margin of the TA (Fig. 664). Females are closest to those of M. cordiformis sp. nov. in having tongue-shaped spermathecae (Fig. 633) but can be distinguished by the epigynal plate consisting of two round lateral lobes instead of a heart-shaped plate (Fig. 622).   
 Etymology. The specific epithet is a Latin adjective concavus (= hollow, concave), which refers to the apically concave anterior margin of the TA.   
 Description. Male  (holotype). Total length 5.67; prosoma 3.50 long, 2.32 wide. Eye sizes and interdistances: AME 0.26, ALE 0.18, PME 0.18, PLE 0.20, AME–AME 0.10, AME–ALE 0.20, PME–PME 0.16, PME–PLE 0.38; MOQ: 0.52 long, 0.50 anterior width, 0.48 posterior width. Leg measurements: I 14.26 (3.44, 4.34, 4.00, 2.46), II 13.58 (3.22, 3.68, 3.42, 3.22), III 11.96 (3.04, 3.48, 3.50, 1.92), IV 16.00 (3.50, 4.70, 5.28, 2.50).   
 Coloration (Fig. 608). Carapace orange-brown. Chelicerae brown. Sternum dark yellowish brown. Legs yellowish, coxae and proximal parts of femora pale yellow. Opisthosoma background sepia. Pattern on dorsum: first pair indistinct; second pair represented by pale round patches; third to fifth pairs by short transverse patches.   
 Palp (Figs 664–667). Retrolateral side of palpal tibia slightly elevated, blunt terminally. RTA relatively short, slightly broad at base, gradually tapered towards round apex. TA rostrated; apico-prolateral process widened terminally, directed mesad; apico-prolateral area poorly developed, concealed by broad and triangular apico-retrolateral fold; retrolateral tooth sharply pointed, directed anteriad. Embolus with longitudinal groove running from proximal part; apex of lateral ramus spatulate; mesal ramus terminally with straight edge.   
 Female (paratype). Total length 6.04; prosoma 3.58 long, 2.30 wide. Eye sizes and interdistances: AME 0.28, ALE 0.20, PME 0.20, PLE 0.20, AME–AME 0.12, AME–ALE 0.20, PME–PME 0.16, PME–PLE 0.39; MOQ: 0.54 long, 0.52 anterior width, 0.49 posterior width. Leg measurements: I 14.14 (3.40, 4.30, 3.96, 2.42), II 13.44 (3.20, 3.64, 3.38, 3.20), III 11.84 (3.00, 3.44, 3.46, 1.92), IV 15.90 (3.48, 4.68, 5.24, 2.48).   
 Coloration. Carapace orange-brown, mesally with a pair of elongate-ovoid patches obliquely arranged. Chelicerae brown. Sternum dark yellowish brown. Legs yellowish, coxae and proximal parts of femora pale yellow. Opisthosoma background sepia. Pattern on dorsum: first pair indistinct; second pair represented by pale round patches; third pair by a chevron; fourth and fifth pairs by short triangular patches.   
 Genitalia (Figs 620, 633, 668–671). Epigynal plate with broad anterior median incision; lateral lobes strongly pronounced, forming globular elevations. Spermathecae tongue-shaped, lateral margins almost parallel, slightly constricted on mesolateral side.   
 Natural history. Mallinella concava sp. nov. was collected in an evergreen hill forest at high altitude.   
 Distribution. Known only from the type locality on Sumatra.
