( Figs 1C–D , 5–6 , 9 ) Type material. Holotype ♂ (IZCAS-Ar42718), the Philippines , Luzon Island , Sagada Town , underground river in a cave (large, humid cave with a river), 17.0849°N , 120.9049°E , elev. ca 1432 m , 28.V.2015 , Francesco Ballarin and Yunchun Li leg. Paratypes . 4♀ (IZCAS-Ar42719–Ar42722), same data as holotype . Diagnosis. The males of the new species resemble H. aoqin sp. nov. by the long and strongly coiled embolus. They can be distinguished from H. aoqin sp. nov. by the embolus coiling 2600° around the MA ( Fig. 5 ) ( vs. 4100° in H. aoqin sp. nov. ( Fig. 2 )), and the embolus without apophysis ( Fig. 5 ) ( vs. embolus with two apophyses in H. aoqin sp. nov. ( Fig. 2D )). Females can be distinguished by the copulatory duct with ten turns ( Fig. 6B ) ( vs. eight turns in H. aoqin sp. nov. ( Fig. 2 )), posterior margin with a distinct indentation ( vs. recurved in H. aoqin sp. nov. ) and the ratio of the length of the spermathecal duct to the length of the spermathecae is almost 3:2 ( Fig. 6B ) ( vs. 5: 1 in H. aoqin sp. nov. ). Description. Male holotype ( Figs 1C , 5 ). Total length 4.38. Carapace 1.91 long, 1.79 wide, pale white with dark green irregular pattern, with a distinct arrow-shaped white mark on cephalic region, margin black. Clypeus height 0.27, dark green anteriorly. Chelicerae yellow-brown, black at base, with eight retromarginal denticles. Eye area dark green around PME and PLE, white arrow pattern posteriorly; eye sizes and interdistances: AME 0.21, ALE 0.13, PME 0.17, PLE 0.18, AME–AME 0.10, AME–ALE 0.08, PME–PME 0.09, PME–PLE 0.12, AME–PME 0.05, ALE–PLE 0.03. Legs pale, with dark green stripe. Leg measurements: leg I: 21.74 (5.30 + 6.39 + 5.71 +3.40 + 0.94), leg II: 21.49 (5.37 + 6.26 + 5.52 + 3.36 + 0.98), leg III: 6.77 (2.05 + 2.11 + 1.87 + 0.74), leg IV: 18.63 (4.58 + 5.34 + 5.20 + 2.63 + 0.88). Leg formula: 1243. Abdomen 2.33 long, 2.18 wide, with black pattern; lancet-shaped cardiac mark; three pairs of greenish-black muscle impressions, laterally black. bS 0.66, tS 2.74. Palp ( Fig. 5 ). Tibia longer than patella, with a hood prolaterally; cymbium long, almost two times longer than wide, with four strong apical spines; tegulum obscured by embolus coils; embolus originating at three o’clock, coiling around median apophysis; median apophysis pointed distally, with a hook-shaped tegular projection. Female paratype ( Figs 1D , 6 ). Colouration and pattern as in male. Total length 5.18. Carapace 2.13 long, 2.02 wide. Clypeus height 0.38. Chelicerae with 8 retromarginal denticles. Eye sizes and interdistances: AME 0.21, ALE 0.18, PME 0.22, PLE 0.11, AME–AME 0.16, AME–ALE 0.14, PME–PME 0.07, PME–PLE 0.08, AME–PME 0.06, ALE–PLE 0.03. Leg measurements: leg I: 19.06 (4.94 + 5.28 + 4.64 +3.18 + 1.02), leg II: 19.46 (4.82 + 5.75 + 4.76 + 3.04 +1.09), leg III: 7.07 (2.20 + 2.17 + 1.88 + 0.82), leg IV: 17.99 (4.67 + 5.03 + 4.51 + 2.73 + 1.05). Leg formula: 2143. Abdomen 2.85 long, 3.12 wide. bS 1.02, tS 4.57. Epigyne ( Fig. 6 ) with epigynal teeth posteriorly; median septum narrowed, separating two oval atria; copulatory opening at anterior part of atria. Copulatory ducts translucent. Spermathecae kidney-shape, spermathecal ducts consistently thin, ratio of length of spermathecal duct to length of spermathecae almost 3:2. Fertilization ducts narrowed, sickle-shaped. Etymology. The species is named after the type locality; noun. Distribution. Known only from the type locality.
