Himalaphantes fugongensis sp. nov. (AEṄẲĦƦ) Figures 138 , 139 , 146

Types. Holotype ♀, CHINA, Yunnan, Fugong County, Yamu river , 27.45910°N, 98.83148°E, alt. 1820m, 26 April 2004, Guang-xu Peng leg. (20040426–2).

Etymology. This epithet derives from the type locality.

Diagnosis. The new species resembles Himalaphantes aduncus sp. nov. in having the similar stretcher and posterior median plate in epigyne ( Fig. 138A–C ; Fig. 130A–C ), but can be distinguished by the spermathecae L-shaped in H. fugongensis sp. nov. ( Fig. 138A–C ), whereas bean-shaped in Himalaphantes aduncus sp. nov. ( Fig. 130A–C ). Scape with the lateral lobe present in H. fugongensis sp. nov. ( Fig. 138A–C ), whereas absent in Himalaphantes aduncus sp. nov. ( Fig. 130A–C ).

Clypeus 0.32 high. Sternum longer than wide, brown. Labium wider than long, brown. Maxillae long, distal end broad with scopulae. Chelicerae yellowish brown, with four promarginal and four retromarginal teeth. Eye region narrow, AER recurved, PER straight, slightly wider than AER. Eye sizes and interdistances: AME 0.13, ALE 0.16, PME 0.14, PLE 0.14, AME–AME 0.03, AME–ALE, 0.04, PME–PME 0.03, PME–PLE 0.05, AME–PME, 0.13, ALE–ALE 0.56, PLE–PLE 0.59, ALE–PLE contiguous. Legs with annuli; length of legs: I 8.81 (2.32, 2.85, 2.38, 1.26), II 7.31 (2.08, 2.34, 1.91, 0.98), III 5.17 (1.55, 1.49, 1.39, 0.74), IV 6.65 (1.94, 1.94, 1.83, 0.94); leg formula I-II-IV-III. Tm I 0.78 and Tm IV 0.51. Tibial dorsal spine formula: 2-2-2-2. Abdomen 2.79 long, 1.79 wide, oval, yellow, proximal end with a longitudinal band followed by irregular greenish-grey patches extending posteriorly; ventral side greenish-grey, with irregular greenish-grey patches.

Epigyne ( Fig. 138A–C ): Scape wider than long, with a deep depression posteriorly and a lateral lobe on each side; stretcher longer than wide with round end. copulatory openings present in lateral pockets. Entrance grooves sinuous. Posterior median plate rectangular. Spermathecae relatively large, L-shaped.

Male. Unknown.

Distribution. Known only from the type locality ( Fig. 146 ).
