Euochin memorabilis sp. nov. (Ḝ凡尧奇e)

Figs 60–68

Type material. Holotype: ♂ ( MHBU-ARA-00023448 ), CHINA: Yunnan Province, Dali City, Nanjian County, Mt. Wuliangshan , 24.6473°N, 100.1538°E, 1898 m elev., 27 July 2021, leg. Y. Mu.

Etymology. The specific epithet is derived from the Latin word memorabilis (meaning remarkable or unforgettable), and refers to its unique morphology of male palps, as well as the difficulty in collecting the specimens.

Diagnosis. The new species is similar to Euochin bamianshanensis (Liu, Wang & Peng, 2020) , E. extraculum Wang & Zhang, 2023 and E. zunyi sp. nov. in the short and scroll-like embolus of male palp, but can be distinguished from them by the combination of following characters: (1) palpal bulb rather wide (from E. bamianshanensis and E. extraculum ); (2) base of embolus with part of the distal haematodocha visible in ventral view (from E. bamianshanensis , E. extraculum and E. zunyi sp. nov.); (3) tip of RTA thick and blunt in retrolateral view (from E. bamianshanensis , E. extraculum and E. zunyi sp. nov.); (4) tegulum with a round hump at the retrolateral shoulder region (from E. bamianshanensis , E. extraculum and E. zunyi sp. nov.).

Description. Male. Habitus shown in Figs 63, 65 . Carapace length 1.178; abdomen length 1.177. Measurements of eyes: AME 0.223, ALE 0.145, PME 0.059, PLE 0.121. Measurements of legs: I 1.750 (0.587, 0.276, 0.398, 0.240, 0.249), II 1.553 (0.513, 0.232, 0.353, 0.218, 0.237), III 1.939 (0.694, 0.252, 0.366, 0.338, 0.289), IV 2.093 (0.678, 0.239, 0.423, 0.425, 0.328); leg formula: 4312. Color in ethanol: carapace dark, margined with a narrow stripe composed of white setae. Abdomen dark. Chelicera ( Fig. 66 ) with two promarginal and one retromarginal teeth. Palp ( Figs 60–62, 64, 67–68 ): patella and tibia covered with long white setae; embolus scroll-like; CyF undeveloped; RTA blunt.

Female. Unknown.

Distribution. China (Yunnan).
