Type material. Holotype: Male, China, Yunnan Province, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Nature Reserve, ground of secondary tropical montane evergreen forest (active searching), 5 – 12 September 2006, G. Zheng leg. Paratypes: 16 males, same locality as for holotype (active searching and pitfall traps), from July to September 2006, G. Zheng leg.; 66 females, same locality as for holotype (active searching and pitfall traps), September 2006 – May 2007, G. Zheng leg.
Etymology. The specific name is taken from the Latin adjective ‘ saccatus ’, meaning saccate, shaped like a pouch or sac and referring its saccate sub-spermathecae; adjective.
Diagnosis. The new species is similar to H. himalayaensis Hu & Zhang, 1990 (Figs 10–13), H. cinerea Emerton, 1890 and H. arizonica Chamberlin & Ivie, 1942 in having tegular setea on male palp and two relative small copulatory openings of epigyne, but can be distinguished from these species by the stout RTA (Figs 14 B–C, 15G–H), the fewer tegular setae (Figs 14 A, 15F) of male palp and the posteriorly located copulatory openings (Figs 14 D, 16E–F), the very short copulatory ducts between openings and bifurcation points and the spherical subspermathecae with relatively wide distance from each other (Figs 14 E, 16G).
Description. Male. Total length 2.30 – 2.60. Holotype (Figs 15 A–E): Total length 2.46. Prosoma 1.32 long, 1.02 wide; opisthosoma 1.20 long, 0.84 wide. Eye sizes and interdistances: AME 0.07, ALE 0.10, PME 0.09, PLE 0.11; AME–AME 0.03, AME–ALE 0.02, PME–PME 0.06, PME–PLE 0.04, ALE–PLE 0.02. MOA 0.22 long, front width 0.16, back width 0.24. Clypeus height 0.13. Chelicerae with distinct lateral condyle, stridulatory files laterally and 3 promarginal, 5 – 6 retromarginal teeth. Leg measurements: I 4.45 (1.27, 1.47, 1.01, 0.70); II 4.06 (1.19, 1.32, 0.91, 0.64); III 3.58 (1.02, 1.10, 0.87, 0.59); IV 4.46 (1.24, 1.40, 1.10, 0.72). Leg formula: 4123. Opisthosoma with 4 chevron-like markings dorsally. Spiracle located centrally.
Male palpal patellar apophysis hooked, originating retro-basally. RTA sharply curved backward, tip pointed. Embolus originating retro-basally, curved clockwise around the tegulum (left palp) and ending near the membranous median apophysis. Set of setae located on tegulum prolaterally. Cymbial furrow deep, its length slightly shorter than half of cymbial length (Figs 14 A–C, 15 F–H).
Female. Total length 2.40 – 3.00. One female paratype (Figs 16 A–D): Total length 2.55. Prosoma 1.35 long, 0.95 wide; opisthosoma 1.40 long, 1.15 wide. Eye sizes and interdistances: AME 0.05, ALE 0.10, PME 0.08, PLE 0.10; AME–AME 0.05, ALE–ALE 0.03, PME–PME 0.08, PME–PLE 0.05, ALE–PLE 0.02. Clypeus height 0.13. Chelicerae with 6 retromarginal teeth (7 or 8 teeh rarely found). Leg measurements: I 3.75 (1.10, 1.30, 0.80, 0.55); II 3.40 (1.00, 1.15, 0.75, 0.50); III 3.15 (0.90, 1.05, 0.75, 0.45); IV 4.20 (1.25, 1.35, 1.00, 0.60). Leg formula: 4123. Other characters as in male.
Epigyne with two small copulatory openings, located in shallow, small atrium and close to epigastric furrow. Copulatory ducts bifurcate near the openings. One branch connecting with sub-spermathecae relatively thick and the other slender. Sub-spermathecae located anteriorly. Spermathecae elliptic, near the posterior margin of epigyne. Fertilization ducts originating from the spermathecae posteriorly and pointing laterally (Figs 14 D–E, 16E–G).
Distribution. Known only from Xishuangbanna rainforest, Yunnan Province, China.
