Diagnosis. Males can be distinguished by the elongated apico-prolateral process, in combination with a broad apical fold on the TA ( Fig. 901 View FIGURES 901–906. 901–904 ). Females can be confused with those of M. amblyrhyncha sp. nov. but differ by the triangular instead of the round dorsal hump ( Figs 892 View FIGURES 891–894. 891 cf. 905), and by the spherical posterior part of spermathecae ( Fig. 905 View FIGURES 901–906. 901–904 ).

Etymology. The specific epithet the superlative of the Latin adjective (angustus = narrow), referring to the apico-prolateral process on the TA of the male palp which is the longest and most slender among Mallinella species.

Description. Male (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).

Coloration ( Figs 843 View FIGURES 836–843. 836 , 845 View FIGURES 844–849. 844–846, 848 ). 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.

Palp ( Figs 852–853 View FIGURES 850–855. 850–851 , 901–904 View FIGURES 901–906. 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.

Female (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).

Coloration. 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.

Genitalia ( Figs 586 View FIGURES 584–586. 584–586 , 905–906 View FIGURES 901–906. 901–904 ). 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.

Natural history. Mallinella angustissima sp. nov. inhabits lowland evergreen rainforests.

Distribution. Eastern Malay Peninsula and Tioman Island.
