L. Monod (MHNG, TM –17). <b>Paratypes: MALAYSIA, <i>Pahang State</i>:</b> 1&amp;male;, near Genting Highland, 100–250 m (2°46’N, 104°08’E), 20 August 2004, leg. A. Schulz.

Schwendinger (MHNG, MAL –04/06). <b>Diagnosis.</b> Males can be distinguished by the elongated apico-prolateral process, in combination with a broad apical fold on the TA (Fig. 901). Females can be confused with those of <i>M</i>. <i>amblyrhyncha</i> sp. nov. but differ by the triangular instead of the round dorsal hump (Figs 892 cf. 905), and by the spherical posterior part of spermathecae (Fig. 905). <b>Etymology.</b> The specific epithet the superlative of the Latin adjective (<i>angustus</i> = narrow), referring to the apico-prolateral process on the TA of the male palp which is the longest and most slender among <i>Mallinella</i> species. <b>Description. Male</b> (holotype). Total length 7.15; prosoma 4.30 long, 3.25 wide. Eye sizes and interdistances: AME 0.30, ALE 0.20, PME 0.20, PLE 0.20, AME–AME 0.12, AME–ALE 0.32, PME–PME 0.24, PME–PLE 0.48; MOQ: 0.60 long, 0.56 anterior width, 0.50 posterior width. Leg measurements: I 17.25 (4.14, 5.40, 4.32, 3.36), II 14.30 (3.60, 4.50, 3.58, 2.58), III 14.38 (3.78, 4.32, 3.86, 2.40), IV 19.88 (4.80, 5.86, 6.20, 3.20). <i>Coloration</i> (Figs 843, 845). Carapace orange-brown. Chelicerae brown. Sternum yellowish brown. Legs yellowish, except for coxae whitish. Dorsum of opisthosoma dark sepia, cardiac region pale. Dorsal pattern: first and second pairs fused, forming pale reniform patches; third pairs elongated, ovoid, obliquely arranged, larger than fourth and fifth pairs. <i>Palp</i> (Figs 852–853, 901–904). Retrolateral margin of palpal tibia triangular, strongly pronounced. RTA elongated, broad at base, gradually tapered towards sharply pointed apex. TA rostrated; apico-prolateral process elongated, slender, sharply pointed, situated posterior to apico-prolateral fold; meso-retrolateral ridge connected to basal tooth. Embolic base ovoid, aligned in longitudinal direction; membranous area narrowed, almost indistinct. Embolus broad, gradually widening towards apex. <b>Female</b> (paratype). Total length 7.60; prosoma 4.55 long, 3.28 wide. Eye sizes and interdistances: AME 0.28, ALE 0.20, PME 0.18, PLE 0.20, AME–AME 0.10, AME–ALE 0.34, PME–PME 0.24, PME–PLE 0.46; MOQ: 0.60 long, 0.50 anterior width, 0.48 posterior width. Leg measurements: I 18.45 (4.42, 5.78, 4.62, 3.58), II 15.30 (3.86, 4.80, 3.84, 2.76), III 15.38 (4.04, 4.62, 4.12, 2.56), IV 21.26 (5.14, 6.26, 6.62, 3.20). <i>Coloration</i>. Carapace orange-brown. Chelicerae brown. Sternum reddish brown. Legs yellowish. Dorsum of opisthosoma sepia. Dorsal pattern: first and second pairs used together, forming pale reniform patches; third to fifth pairs represented by pale ovoid spots, third ones largest, obliquely arranged. <i>Genitalia</i> (Figs 586, 905–906). Epigynal plate quadrangular, almost as wide as long; posterior margin rebordered, protruding over epigastric furrow. Internal genitalia without clear separation between insemination ducts and spermathecae. Spermathecae divided into upper and lower regions: upper part triangular in dorsal view, bluntly pointed, provided with triangular dorsal tubercle; lower part spherical. <b>Natural history.</b> <i>Mallinella angustissima</i> sp. nov. inhabits lowland evergreen rainforests. <b>Distribution.</b> Eastern Malay Peninsula and Tioman Island.
