Q. Mi et al. leg.; • 1 ♂ 1 ♀ (TRU -Oxy-0015 –0016), Motuo Co., Renqingbengsi, Yarlung Zangbu Grand Canyon NNR (29°18.31'N, 95°21.29'E, ca 1970 m), 26 May 2024, X. Q. Mi et al. leg.
Etymology.
The specific name is in honor of Fu Shu (舒服) (Changsha, China), for his assistance in collecting specimens in the Yarlung Zangbu Grand Canyon.
Diagnosis.
The male of the new species is similar to that of H. cordata Zhang, Zhu & Song, 2005 in having a hook-shaped median apophysis (MA) and a ramose conductor (C), but can be easily distinguished by the following: (1) ventral tibial apophysis (VTA) tapers in ventral view (Fig. 5 A) vs broadened distally (Zhang et al. 2005: fig. 9); and (2) prolateral apophysis (PA) extends anteriorly in ventral view (Fig. 5 A) vs anteroretrolaterally (Zhang et al. 2005: fig. 9). The female of this new species is similar to that of H. cucullata Tang, Wang & Peng, 2012 in having an epigynal hood (H), but can be distinguished by the following: (1) copulatory openings (CO) open anteriorly (Fig. 9 A, C) vs posterolaterally (Tang et al. 2012: figs 8, 10, 14); (2) atrium (At) is approximately 1.75 × wider than long (Fig. 9 A, C) vs approximately 1.2 × wider than long (Tang et al. 2012: figs 8, 10, 14); and (3) epigynal hood (H) is hollowed centrally (Fig. 9 A, C) vs not hollowed (Tang et al. 2012: figs 8, 10, 14).

Carapace oval, red-brown with irregular yellow stripe behind eye area and lateral dark brown stripes, posteriorly covered with white scales, eye area dark. Chelicerae red-brown. Endites yellow, covered with short setae. Labium mainly brown, with dense, anteromarginal dark setae. Sternum red-brown. Legs pale yellow, spination of leg I: femur d 2 p 2 r 1; patella d 1 r 1; tibia d 1 p 4 r 3; metatarsi d 1 p 3 r 4. Abdomen long-elliptical, dorsum yellow-brown, darker posteriorly, with median, faint patches; venter pale yellow in general, covered with short setae.
Palp (Figs 5, 6 E, F): femur length / width ratio ca 1.74; patella almost as long as wide; ventral tibial apophysis (VTA) straight, tapered to blunt end directed towards about 12: 00 o’clock position in ventral view; retrolateral tibial apophysis (RTA) sub-square in ventral view; cymbium length / width ratio ca 1.3, with baso-retrolateral fold (CF); tegulum with anteriorly extended prolateral apophysis (PA) and postero-prolaterally extended posterior lobe; median apophysis (MA) enlarged and weakly sclerotized at base, remainder hook-shaped and with pointed end; embolus (E) curved to half circle and distally hidden by conductor (C); conductor anteroretrolaterally located, ramose distally.
Female (paratype, TRU -Oxy-0014, Figs 1 F, 9). Total length 4.77. Carapace 2.27 long, 1.65 wide. Abdomen 2.50 long, 1.92 wide. Eye sizes and interdistances: AME 0.10, ALE 0.17, PME 0.13, PLE 0.13; AME – AME 0.13, AME – ALE 0.08, ALE – PLE 0.19, PME – PLE 0.25, PME – PME 0.21.
