Etymology. This epithet proposed on the name of Pula river.

Diagnosis. Himalaphantes pulae sp. nov. can be distinguished from all other congeners by the scape mid-ventrally with a small tongue-shaped projection and laterally with broad round lobe; posterior median plate posteriorly round; stretcher as wide as long, narrow posteriorly ( Fig. 144A–C ).

Description: Female (holotype, Fig. 145A, B ): Total length: 3.76; carapace 1.37 long, 1.08 wide, yellowish brown; cephalic region slightly elevated, with a brown band, lateral sides brown; fovea, cervical and radial grooves distinct. Clypeus 0.21 high. Sternum longer than wide, brown. Labium wider than long, brown. Maxillae long, distal end broad with scopulae. Chelicerae yellowish brown, with three promarginal and five retromarginal teeth. Eye region narrow, AER recurved, PER straight, slightly wider than AER. Eye sizes and interdistances: AME 0.10, ALE 0.09, PME 0.11, PLE 0.10, AME–AME 0.05, AME–ALE, 0.03, PME–PME 0.05, PME–PLE 0.04, AME–PME, 0.08, ALE–ALE 0.48, PLE–PLE 0.51, ALE–PLE contiguous. Legs with annuli; length of legs: I 8.20 (2.38, 2.46, 2.02, 1.34), II 6.72 (1.92, 1.74, 1.93, 1.13), III 4.72 (1.41, 1.46, 1.11, 0.74), IV 6.37 (1.82, 1.88, 1.78, 0.89); leg formula I-II-IV-III. Tm I 0.67 and Tm IV 0.53. Tibial dorsal spine formula: 2-2-2-2. Abdomen 2.40 long, 1.88 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. 144A–C ): Scape mid-ventrally with a small tongue-shaped projection and laterally with broad round lobe; stretcher as wide as long, narrow posteriorly. copulatory openings present in lateral pockets. Entrance grooves sinuous. Posterior median posteriorly round. Spermathecae relatively large, L-shaped.

Male. Unknown.

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

Himalaphantes zhangmuensis ( Hu, 2001) comb. nov. (Θ‡ẲĦƦ)

Lepthyphantes zhangmuensis Hu, 2001: 514 , f. 342.1–3 (Df).

Distribution. China.

Remarks. Lepthyphantes zhangmuensis Hu, 2001 , more closely related to the genus Himalaphantes by the combination of the following characters: Scape is relatively broad; spermathcae are large and C-shaped; the posterior median plate is robust and covers the stretcher anteriorly; and the stretcher is large. With all of these characters, L. zhangmuensis shows more proximity to the genus Himalaphantes . Hence, it is proposed here as Himalaphantes zhangmuensis ( Hu, 2001) comb. nov..
