Type material. Holotype: male, VIETNAM, NINH BINH PROVINCE, Cuc Phuong National Park, natural forest, pitfall traps, 1–30.X.2007. Paratypes (57 males, 27 females): 26 males, 1 female, same data as holotype; 1 male, 2 females, same data as holotype but: 1–30.VI.2007; 1 female, same data as holotype but: 1–30.VII.2007; 28 males, same data as holotype but: 1–30.VIII.2007; 2 males, 23 females, same data as holotype but: 1–30.XI.2007.

Etymology. The specific name is taken from the Latin word “ rimiformis ”, meaning split-like and referring to the shape of the epigynal atrium, adjective.

Diagnosis. The new species is similar to H. himalayaensis ( Figs 3A–E View FIGURES 3 A – E ) in having tegular setae and long copulatory ducts, but differs from the latter by the smaller number of setae and the long cymbial furrow; and a splitlike epigynal atrium, the small subspermathecae far away from spermathecae ( Figs 4A–B, 4D, 4F View FIGURES 4 A – F ).

Description. Male holotype ( Figs 5A–D View FIGURES 5 A – G ): Total length 2.25. Prosoma 1.13 long, 0.83 wide; opisthosoma 1.25 long, 0.82 wide. Eye sizes and interdistances: AME 0.05, ALE 0.09, PME 0.07, PLE 0.08; AME–AME 0.03, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.03, ALE–PLE 0.02. MOA 0.17 long, front width 0.12, back width 0.19. Clypeus height 0.12. Leg measurements: I 3.61 (1.02, 1.20, 0.80, 0.59); II 3.35 (0.94, 1.07, 0.75, 0.59); III 3.11 (0.85, 0.95, 0.78, 0.53); IV 3.78 (1.01, 1.24, 0.96, 0.67). Leg formula: 4123. Chelicerae with 3 promarginal and 5 retromarginal teeth.

Male palp ( Figs 4A–C View FIGURES 4 A – F , 5E–G View FIGURES 5 A – G ) with a sheet-like, hooked patellar apophysis and a long and curved RTA. Another protuberance present on the dorsal margin of retrolateral side of tibia. Embolus long, retrolateralproximally originated and its tip lying in the cymbial furrow. Median apophysis membranous, originating retrolaterally. Cymbial furrow long and deep.

One of female paratypes ( Figs 6A–B View FIGURES 6 A – G ) total length 2.34. Prosoma 1.67 long, 0.81 wide; opisthosoma 1.29 long, 0.94 wide. Eye sizes and interdistances: AME 0.05, ALE 0.07, PME 0.07, PLE 0.09; AME–AME 0.04, AME–ALE 0.02, PME–PME 0.06, PME–PLE 0.05, ALE–PLE 0.03. MOA 0.18 long, front width 0.13, back width 0.21. Clypeus height 0.12. Leg measurements: I 3.15 (0.94, 1.11, 0.56, 0.54); II 2.99 (0.89, 0.97, 0.62, 0.51); III 2.77 (0.77, 0.86, 0.63, 0.51); IV 3.68 (1.05, 1.18, 0.86, 0.59). Chelicerae with 3 promarginal and 5–6 retromarginal teeth (some other female paratypes with 3–4 promarginal and 5–6 retromarginal ones). Other characters similar to the male holotype.

Epigyne with an elevated, split-like atrium ( Figs 4D View FIGURES 4 A – F , 6C–D View FIGURES 6 A – G ) near the epigastric furrow. Atrium pit-like if degraded backwards ( Figs 4E View FIGURES 4 A – F , 6E–F View FIGURES 6 A – G ). Copulatory ducts slender and strongly curved. Subspermathece slightly inflated and located anteriorly. Spermathecae located posteriorly, widely separated from each other ( Figs 4F View FIGURES 4 A – F , 6G View FIGURES 6 A – G ). A pair of epigynal hoods can be located behind of the epigastric furrow, their distance wider than twice of the width of copulatory openings ( Fig. 4D View FIGURES 4 A – F ).
