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]).

Coloration. Carapace gray, with one black longitudinal stripe nearly same width as eye area. Abdomen gray, with a narrow and wedge shape dorsal scutum, large black pattern beside dorsal scutum, four black transverse stripes at posterior of abdomen (Fig. 40A, B). Legs gray-white.
Palp as in Figs 41A–D, 42A–C. Femoral apophysis well developed, nearly at middle of femur. Tibia about half length of femur. Prolateral tibial apophysis distinct, round. Retrolateral tibial apophysis base thick, extending towards retrolateral side, then folding upwards, dagger-shaped in retrolateral view, curved in dorsal view. Tegulum oval, wider than cymbium; tegular apophysis oxhorn-shaped in retrolateral view, located at tip of tegulum retrolaterally. Sperm duct distinct, tapering from retrolateral side of tegulum to embolus. Embolus wide, curved, almost L-shaped. Conductor absent.
