The specific epithet refers to the species’ similarity to H. corticicola Bösenberg & Strand 1906 . Diagnosis. The new species is similar to H. corticicola ( Figs 3A–I ) in having similarly shaped patellar apophysis, RTA, median apophysis, tegulum, and long and deep cymbial furrow as well as a similarly positioned copulatory opening, but it can be distinguished by the pointed apex of the male palpal cymbium, the equally long cymbium and cymbial furrow, the presence of a small tegular apophysis near the base of the embolus, the extremely slender embolus with its tip embedded in a pocket ( Figs 1A–C , 2E–G ), the protruding median part of the posterior margin of the copulatory opening, the long, multi-coiled copulatory ducts and the distinct subspermathecae of the epigyne (1D–E, 2H–I). Description. Male holotype ( Figs 2A, C–D ) total length 1.77. Prosoma 0.78 long, 0.68 wide; opisthosoma 1.09 long, 0.81 wide. Carapace pear-shaped with dark markings in radial furrows and cervical groove. Fovea longitudinal, brown. Cephalic area elevated. Eight eyes with distinct black rims. Eye sizes and interdistances: AME 0.03, ALE 0.06, PME 0.05, PLE 0.05; AME–AME 0.03, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.02, ALE–PLE 0.01. MOA 0.12 long, front width 0.09, back width 0.14. Clypeus height 0.12. Chelicerae yellowish with three promarginal and three retromarginal teeth. Gnathocoxae of equal length and width. Labium wider than long. Sternum cordiform with dark marginal markings. Legs yellow with some spines. Leg measurements: I 2.25 (0.66, 0.75, 0.48, 0.36); II 2.11 (0.63, 0.68, 0.44, 0.36); III 1.95 (0.55, 0.62, 0.44, 0.34); IV 2.41 (0.67, 0.79, 0.56, 0.39). Leg formula: 4123. Opisthosoma oval, greyish black with a light quadrate and five light chevrons dorsally. Tracheal spiracle equidistant between the epigastric furrow and the base of spinnerets. FIGURES 3A–I .

Eyes and chelicerae of male, frontal view; D. Left male chelicera, ventral view; E. Left male palp, ventral view; F. Same, retrolateral view; G. Same, dorsal view; H. Epigyne, ventral view; I. Vulva, dorsal view. Male palp ( Figs 1A–C , 2E–G ) with a hook-like, relatively thin and long patellar apophysis. Distal part of RTA filiform extending dorsally and then proximally. Cymbium with a very deep, long and semi-transparent retrolateral furrow. Embolus originating retrolaterally, clockwise curved along the cymbial margin, then anticlockwise curved inside the cymbial furrow. End of embolus embedded in a transparent pocket. Median apophysis membranous, located near the base of embolus. One female paratype (collected with holotype , Fig. 2B ) total length 2.03. Prosoma 0.81 long, 0.59 wide; opisthosoma 1.26 long, 0.95 wide. Eye sizes and interdistances: AME 0.04, ALE 0.05, PME 0.05, PLE 0.05; AME– AME 0.02, AME–ALE 0.01, PME–PME 0.05, PME–PLE 0.03, ALE–PLE 0.01. MOA 0.13 long, front width 0.09, back width 0.13. Clypeus height 0.09. Leg measurements: I 1.96 (0.59, 0.66, 0.39, 0.32); II 1.83 (0.57, 0.59, 0.37, 0.30); III 1.72 (0.54, 0.54, 0.37, 0.27); IV 2.28 (0.66, 0.75, 0.50, 0.37). Leg formula: 4123. Epigyne ( Figs 1D–E , 2H–I ) with a pair of small copulatory openings medio-posteriorly with posterior margins visible. Copulatory ducts quite long and strongly convoluted as three coils. Subspermathecae located anteriorly, visible in the gap of copulatory duct loops. Spermathecae located centrally in the loops of copulatory ducts. Fertilization ducts extending posteriorly and curving medially. Distribution. China (Chongqing, Hubei, Anhui) ( Fig. 4 ). Remark. The new species was collected in the leaf litter of an old-growth forest area, specifically, along the Yangtze River basin, close to the latitude 30° North.
