Type material. Holotype: ♁ (MHBU-ARA-00023463), CHINA: Guangxi Zhuang Autonomous Region, Hezhou City, Babu District, Daguishan Natural Reserve, Qixingchong, Dadong Patrol Station (kffƜOiḞLJƖAEṗfi âkdzúḞ⁂), 24.072222°N, 111.598333°E, 722 m a.s.l., 9 May 2021, leg. Y. Mu & W. Wang. Paratypes: 2♀ (MHBU-ARA-00025230), same data as holotype.
Etymology. The new species is named after a well-known ancient Chinese litterateur, Dongpo Su, who was relegated to the Lingnan Region (including Guangxi and Guangdong) and left many anecdotes there; he profoundly influenced the folk culture of southern China. Noun (name) in apposition.
Diagnosis. Both sexes resemble Euochin bulbus and E. atrata (Song & Chai, 1992), but can be easily distinguished by the non-furcated retromarginal tooth of the chelicera (Fig. 39; vs. furcated retromarginal tooth in E. bulbus and E. atrata, see Bao & Peng 2002: fig. 14; Zha et al. 2014), the narrower distal part of the embolus (Figs 40–44, vs. strikingly broadened in E. bulbus and E. atrata, see Zha et al. 2014: figs 6, 9, 16–17, 19), and the copulatory duct without obvious accessory gland (Figs 46, 50; vs. copulatory duct with highly developed accessory gland in E. bulbus and E. atrata, see Zha et al. 2014: figs 4, 11, 15, 22; Yu et al. 2021: fig. 1G).
Description. Male. Habitus see Figs 35, 37. Carapace length 1.604; abdomen length 1.377. Eye measurements: AME 0.372, ALE 0.250, PME 0.070, PLE 0.218. Leg measurements: I 2.781 (0.909, 0.421, 0.675, 0.447, 0.329), II 2.382 (0.829, 0.347, 0.532, 0.339, 0.335), III 2.667 (1.003, 0.168, 0.636, 0.536, 0.324), IV 2.858 (0.938, 0.318, 0.563, 0.641, 0.398); leg formula: 4132. Color in ethanol: carapace dark, with white setae. Abdomen dark, with white bands and patches. Chelicera (Fig. 39) with two promarginal and one retromarginal teeth. Palp (Figs 40–44, 47–48): tibia and dorsal cymbium with long white setae; embolus ribbon-like, tip with membrane surrounding opening of sperm duct; cymbial flange narrow; RTA straight, finger-like.
Female. Habitus see Figs 36, 38. Carapace length 1.913; abdomen length 1.480. Eye measurements: AME 0.460, ALE 0.302, PME 0.085, PLE 0.232. Leg measurements: I 3.106 (1.009, 0.545, 0.714, 0.446, 0.392), II 2.691 (0.902, 0.382, 0.618, 0.394, 0.395), III 3.518 (1.238, 0.506, 0.660, 0.717, 0.397), IV 3.610 (1.132, 0.408, 0.762, 0.835, 0.473); leg formula: 4312.
