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]
).
