( Figs. 3 , 13–16 , 26 , Map 1 )

Trachystola vitalisi Pic, 1925: 17 . Type locality: Tonkin, Vietnam.

Eshinoschema tonkinense Breuning, 1938: 188 . Type locality: Tonkin, Vietnam. Synonymized by Breuning, 1944: 378.

Propedicellus vitalisi : Huang, Huang & Liu 2020: 522.

Material examined. China (Yunnan): 1 female, China, Yunnan, Zhenyuanxian , Jiujiaxiang , 2,160 m, 2009.VIII.1– 3, leg. Ji-Shan Xu & Jian-Xiong Zhang ( CCCC) ; 1 female, China, Yunnan, Zhenyuan , Hepingxiang , Ailaoshan , 2,299 m, 2019.IX.25, leg. Ying-Hui Li ( CCCC) ; 1 male, China, Yunnan, Jinping , Fenshuiling , 2,311 m, 2012.IX.24, leg. Jia-Hong Lin ( CCCC) ; 1 male, China, Yunnan, Lvchun , Huanglianshan , 1,850 m, 2018.VI.17, Leg. Y.-Q. Lu ( CCCC) ; 1 male, ditto except 2,000 m, 2019.VIII.26, leg. Wen-Xuan Bi ( CBWX) ; 1 female, ditto except 1,980 m, 2019.VIII.28, leg. Wen-Xuan Bi ( CBWX) .

Complementary description. Male ( Fig. 3 ). External morphology mainly refers to Huang et al. (2020). The pronotal discal maculae of light-colored pubescence are partially variable from moderately long stripes to very small spots ( Figs.13–16 ), and elytral discal granules are variable from moderately dense to very sparse.

Endophallus ( Fig. 26 ) smoothly S-shaped, moderately long and slender. MPH subdivided into MT+CT and PB; MT+CT roughly straight, slightly constricted before its midlength, moderately wrinkled on both sides in basal half, provided with two ltc at each side distally, the dorsal ones relatively small ( Fig. 26b ); PB gently constricted toward moderately developed anterior bulb. APH subdivided into ab and bb; ab conical shaped; bb slender, extremely elongated and distinctly swollen distally, with gn situated at its dorsal side near the base.

Distribution ( Map 1 ). China (new Country record): Yunnan (Zhenyuan County; Jinping County; Lvchun County); Vietnam: Tonkin.

Remarks. This species close to E. guoliangi or E. qiului , however can be recognized by the elytra with the subbasal bumps relatively higher elevated and the subapical dorsolateral carinae (as “marginated portion” in Huang et al. 2020) strongly protruding laterally, partially covering elytral lateral margins in dorsal view. It is also unique among the congeners by the male endophallus provided with two ltc on each side, and bb developed, extremely elongated.
