Types. Holotype ♂, CHINA, Yunnan; Nujiang Prefecture, Nujiang State Nature Reserve, No. 12 bridge Camp area , 16.3 km W of Gongshan, 27.71503°N, 98.50244°E, alt. 2775m, 15–19 July 2000, Heng-mei Yan, D. H. Kavanaugh, Charles Griswold, Hong-bin Liang, Darrell Ubick and Da-zhi Dong leg. (00–QD) GoogleMaps . Paratypes: 3♂ 1♀, same data as holotype (00–QD) GoogleMaps .

Etymology. This epithet derives from the Latin adjective “ longi ” and word “scapus”, meaning “long” and “scape” respectively, and referring to long scape in epigyne.

Diagnosis. The new species resembles Bathyphantes ansulis sp. nov. in having the similar short curved embolus in male palp and long scape in epigyne ( Fig. 34A–D View FIGURE 34 ; Fig. 30A–D View FIGURE 30 ), but can be distinguished by the paracymbium U-shaped retrolateral view in B. longiscapus sp. nov. ( Fig. 34B View FIGURE 34 ), whereas J-shaped in B. ansulis sp. nov. ( Fig. 30B View FIGURE 30 ). The anterior projection of embolic plate bifurcated, with teeth at the prolateral surface of apical portion in B. longiscapus sp. nov. ( Figs 34A, B View FIGURE 34 , 35A–C View FIGURE 35 ), whereas not bifurcated and without teeth in B. ansulis sp. nov. ( Fig. 30B View FIGURE 30 ). The ventral process of lamella longer, with broad ear lobe-shaped distal end in B. longiscapus sp. nov. ( Figs 34A, B View FIGURE 34 , 35A–C View FIGURE 35 ), whereas shorter with pendulum shaped distal end in B. ansulis sp. nov. ( Fig. 30B View FIGURE 30 ). Epigyne: the scape longer, completely covering the parmula in ventral view in B. longiscapus sp. nov. ( Fig. 36A–C View FIGURE 36 ), whereas shorter, partly covering the parmula in B. ansulis sp. nov. ( Fig. 31A–C View FIGURE 31 ). Spermathecae pointing towards each other in B. longiscapus sp. nov. ( Fig. 36B, C View FIGURE 36 ), whereas pointing away from each other in B. ansulis sp. nov. ( Fig. 31B, C View FIGURE 31 ).

Description. Male (holotype, Fig. 35D, E View FIGURE 35 ): Total length: 1.88. Carapace 0.94 long, 0.67 wide, the cephalic region brown, slightly elevated; fovea, cervical and radial grooves distinct. Clypeus 0.24 high. Sternum longer than wide, dark brown sparsely covered with microsetae. Labium wider than long. Maxillae long, distal end broad with scopulae. Chelicerae with five promarginal and three retromarginal teeth. Eye region narrow, AER recurved, PER straight and slightly wider than AER.

Palp ( Figs 34A–D View FIGURE 34 , 35A–C View FIGURE 35 ): Tibia conic, with one retrolateral and one dorsal trichobothria, with many short or long spine-like hairs on all surfaces. Paracymbium sclerotized, U-shaped, distal tip ear lobe-like; tegulum with a prominent bulge on ectal side; the distal suprategular apophysis thumb-shaped, covered by the tegulum and embolic division in unexpanded palp; median membrane extending out through the base of embolic plate with thread-like projections on prolateral surface of apical portion; embolic plate highly sclerotized, broad; dorsal projection of embolic plate slightly touches the cymbium in prolateral view; anterior projection of embolic plate thick, distal part bifurcated, with teeth at the prolateral surface of apical portion, ventral process of lamella curved, protruding upward, distal part ear lobe-shaped; embolus thick, highly sclerotized, slightly curved.

Female (paratype, Fig. 37A, B View FIGURE 37 ): Total length: 2.42. Carapace 0.97 long, 0.72 wide, the cephalic region slightly elevated, brown; fovea, cervical and radial grooves distinct. Clypeus 0.19 high. Sternum longer than wide, dark brown sparsely covered with microsetae. Labium wider than long. Maxillae long, distal end broad with scopulae. Chelicerae with five promarginal and three retromarginal teeth. Eye region narrow, AER recurved, PER straight and slightly wider than AER.

Tm I 0.48 and Tm IV 0.39. Tibial spine formula: 2-2-2-2. Abdomen 1.45 long, 0.96 wide, oval, dorsally with distinct patterns of alternative dark greenish-grey and light patch extending from the anterior margin of abdomen to the base of spinnerets, ventral side dark without any marking.

Epigyne ( Fig. 36A–C View FIGURE 36 ): Ventral plate simple; scape Finger-like, wider anteriorly, parmula short and completely covered by scape; copulatory openings present in the atrium; copulatory ducts forming a single loop before joining to the spermathecae; spermathecae globular, present at the apex of the dorsal plate, pointing towards each other; fertilization ducts long and extending mesally.
