(AEȐŴṚff) Figs 40–42 Type material. Holotype ♁, CHINA : Hunan Province : Xiangxi Tujia and Miao Autonomous Prefecture , Yongshun County , Bijiashan ( 28.983211°N , 109.813074°E , 331 m a.s.l. ), 13 Nov. 2018 , leg. Zhaoyi Li. Paratypes : 1 ♁ 6 ♀ , with same data as holotype . Etymology. This specific name is derived from the Latin word “ striatus ”, referring to the longitudinal black stripe on carapace. Diagnosis. This new species resembles O. acutangula Liu, 2020 in having a similarly shaped embolus, but can be recognized by: 1) the smaller and thinner tegular apophysis (vs large and wide, cf. Fig. 41C and fig. 7D in Liu et al. [2020] ), 2) the wider, dagger-shaped retrolateral tibial apophysis in retrolateral view, which is curved in dorsal view (vs thin and digitiform, not curved, cf. Fig. 41B, D and fig. 7E, F in Liu et al. [2020] ), 3) the wider median septum (vs narrow, cf. Fig. 41E and fig. 8C in Liu et al. [2020] ), 4) the slanted, slightly curved connecting tubes (vs straight, nearly transverse, cf. Fig. 41F and fig. 8D in Liu et al. [2020] ). Description.
