Tchatkalophantes lingulatis sp. nov. (ŮḦ※Ʀ) Figures 308–310

Types. Holotype ♀, CHINA, Yunnan, Nujiang Prefecture, Lushui County, Sanjiang Township , Nu Jiang , 25.72964°N, 98.87180°E, alt. 790m, 26 June 2000, D. H. Kavanaugh, Charles Griswold and Heng-mei Yan leg. (00–Lan).

Etymology. This epithet derives from the Latin adjective “ lingulatis ”, meaning “tongue-shaped”,referring to the tongue-shaped stretcher (St) in epigyne.

Diagnosis. The new species resembles Tchatkalophantes tarabaevi Tanasevitch, 2001 in having the distal part of the “pseudoscape” emargination being flanked by two small knobs ( Fig. 308A–D ; Tanasevitch, 2001, fig. 39), but can be distinguished by the posterior margin of pseudoscape narrow in ventral view in T. lingulatis sp. nov. ( Fig. 308A ), whereas posterior margin broad in T. tarabaevi ( Tanasevitch, 2001, fig. 37). Spermathecae C-shaped in T. lingulatis sp. nov. ( Fig. 308B ), whereas kidney-shaped in T. tarabaevi ( Tanasevitch, 2001 fig. 37).

Length of legs: I 4.56 (1.21, 1.53, 1.08, 0.74), II 3.96 (1.07, 1.27, 0.97, 0.65), III 3.17 (0.89, 1.01, 0.76, 0.51), IV 4.34 (1.22, 1.41, 1.06, 0.65). Leg formula I-IV-II-III. Tm I 0.53 and Tm IV 0.46. Tibial spine formula: 2-2-2-2. Abdomen 1.67 long, 1.18 wide, oval, dorsally provided with distinct transverse grayish patches extending from the anterior margin of abdomen to the base of spinnerets; ventral side green.

Epigyne ( Fig. 308A–D ): The distal part of the “pseudoscape” emargination being flanked by two small knobs, longer than wide, narrow posteriorly with well developed stretcher; stretcher tongue-shaped; entrance groove inside lateral pockets; posterior median plate slightly covering the stretcher; spermathecae C-shaped.

Male. Unknown.
