(CAS _DHK-2006-021B). <b>Etymology.</b> The specific name is an adjective from the Latin word <i>cucullata</i> (hood-shaped), and refers to the large hood-shaped conductor of the male palp. <b>Diagnosis.</b> The females of <i>Hamataliwa cucullata</i> <b>sp. nov.</b> and <i>H. torsiva</i> <b>sp. nov.</b> can be separated from all other congeneric species by the covering of the copulatory opening, which is covered with a raised sclerite. The female of this new species <i>H. cucullata</i> can be easily distinguished from <i>H. torsiva</i> <b>sp. nov.</b> by (compare Figs 8, 10, 14 with Figs 19, 21, 23) the larger epigynal depression, the presence of a small hood on the epigynum (absent in <i>H. torsiva</i> <b>sp. nov.</b>) and the absence of a posteriorly sclerotized rim on the epigynum (present in <i>H. torsiva</i> <b>sp. nov.</b>). The male of this new species can be separated from all other congeneric species (e.g. <i>H. foveata</i> Tang &amp; Li, 2012, <i>H. pilulifera</i> Tang &amp; Li, 2012) by the long digitiform VTA and the large, hood-shaped conductor (see Figs 4–6, 12–13). <b>Description. Male</b> (holotype measured): Total length 4.00. Prosoma 1.70 long, 1.45 wide; opisthosoma 2.10 long, 1.30 wide. Carapace grayish brown with grayish white scales. Ocular area black with light gray scales. Eye measurements: AME 0.08; ALE 0.18; PME 0.13; PLE 0.14; AME-AME 0.08; AME-ALE 0.06; PME-PME 0.22; PME-PLE 0.22. Eye row width measurement: I 0.21, II 0.46, III 0.78, IV 0.45. Clypeus height 0.28. Sternum light brown, margin dark gray; chelicera and endites yellowish brown, labium dark gray, chelicera with two promarginal (one large, one small) and one small retromarginal tooth (Fig. 3). Legs light grayish brown with long spines. Leg measurements: I 6.20 (1.80, 2.10, 1.50, 0.80); II 5.90 (1.70, 2.00, 1.40, 0.80); III 4.10 (1.20, 1.30, 1.00, 0.60); IV 4.20 (1.20, 1.40, 1.00, 0.60), leg formula: 1243. Opisthosoma elongated oval, dorsally dark gray with grayish white scales; ventrally gray with longitudinal dark gray markings. <i>Palp</i> (Figs 4–6, 12–13). VTA long digitiform, RTA wider basally, the distal portion beak-shaped in retrolateral view; conductor conspicuous, large-hood-shaped, median apophysis digitiform in lateral view, the distal end of embolus covered by the conductor. <b>Female</b> (one paratype, same data as holotype (HNU_YHY09)): Total length 4.50. Prosoma 1.80 long, 1.50 wide; opisthosoma 2.50 long, 1.80 wide. Carapace dark brown with grayish brown scales. Eye measurements: AME 0.08; ALE 0.18; PME 0.14; PLE 0.14; AME-AME 0.10; AME-ALE 0.05; PME-PME 0.26; PME-PLE 0.24. Eye row width measurement: I 0.25, II 0.52, III 0.88, IV 0.50. Clypeus height 0.32. Chelicera with 2 pro- (one large, one small) and one large retromarginal tooth. Legs dark brown with long spines. Leg measurements: I 6.15 (1.90, 2.20, 1.30, 0.75); II 5.70 (1.70, 2.10, 1.20, 0.70); III 4.65 (1.40, 1.70, 1.00, 0.55); IV 4.50 (1.50, 1.50, 1.00, 0.50), leg formula: 1234. Opisthosoma dorsally brown with blackish brown stripes; ventrally yellow with longitudinal gray markings. <i>Epigynum</i> (Figs 8–11, 14–15). Epigynun with a large central depression, posteriorly with a pair of sclerites covered the copulatory openings. Between the sclerites is a small hood, which can be observed clearly from slightly different angles. Copulatory ducts transparent, twisted; spermathecae globular; fertilisation ducts visible. <b>Variation.</b> Male total length from 4.00–4.80 (n=4), female total length from 3.60–4.00 (n=9). <b>Distribution.</b> China (Yunnan).
