Zabka dianmian sp. nov. (DZšĸe)

Figs 177–198

Type material. Holotype: ♂ ( MHBU-ARA-00025265 ), CHINA: Yunnan Province, Tengchong City, Xinhua Village , 24.2490°N, 98.1126°E, 2089 m elev., 13 April 2023, leg. W. Wang.

Paratypes: 1♂ 1♀ ( MHBU-ARA-00025241 ), same data as holotype .

Etymology. The specific epithet is derived from the memorable Dianmian Road (also known as the Burma Road) during World War II, which passed through the type locality and contributed greatly to the victory of the Chinese People's War of Resistance Against Japanese Aggression. Noun in apposition.

Diagnosis. Males can be easily distinguished from Z. cooki by the presence of TB, and from Z. xuyei ( Lin & Li, 2020) by lacking the peculiar spur bump on the dorsal cymbium. Female differs from Z. cooki by the coloration of abdomen, and from Z. xuyei by the relative position of epigynal window and spermathecae (completely overlapped in Z. xuyei , but nearly half of spermathecae not overlapped with epigynal window in Z. dianmian sp. nov.).

Description.Male. Habitus shown in Figs 183,185 .Carapace length1.646; abdomen length1.719.Measurements of eyes: AME 0.347, ALE 0.245, PME 0.065, PLE 0.203. Measurements of legs: I 3.005 (0.982, 0.455, 0.730, 0.483, 0.355), II 2.570 (0.895, 0.375, 0.574, 0.364, 0.362), III 2.883 (1.083, 0.185, 0.687, 0.578, 0.350), IV 3.085 (1.013, 0.343, 0.608, 0.692, 0.429); leg formula: 4132. Color in ethanol: carapace dark. Abdomen dark brow. Chelicera ( Fig. 187 ) with two promarginal and one retromarginal teeth. Palp ( Figs 188–189 , 192–196 ): distal femur, patella and tibia with long white setae; embolus relatively thick; CyF slightly extended; RTA finger-like.

Female. Habitus shown in Figs 184, 186 . Carapace length 1.783; abdomen length 2.501. Measurements of eyes: AME 0.389, ALE 0.301, PME 0.069, PLE 0.233. Measurements of legs: I 3.051 (1.044, 0.373, 0.768, 0.470, 0.396), II 2.834 (0.981, 0.405, 0.638, 0.430, 0.380), III 3.235 (1.060, 0.390, 0.687, 0.666, 0.432), IV 4.073 (1.331, 0.461, 0.833, 0.887, 0.561); leg formula: 4312. Color in ethanol: similar to that of male. Chelicerae as in male. Epigyne ( Figs 190–191 , 197–198 ): epigynal window with wide margin; copulatory openings located centrally at the postero-central margin of epigynal window; copulatory ducts long and thick; spermathecae globular.

Distribution. China (Yunnan).
