Etymology.
The species name is derived from the

locality; noun in apposition.
Diagnosis.
This new species resembles
O. triangula
Mu, Jin & Zhang,
2022
in having a similarly shaped embolus and spermathecae, but can be recognized by: 1) the absence of a scar on the embolus (vs with scar, cf.
Fig. 38B, C
and fig. 11B, C in Mu
et al.
[2022]), 2) the longer retrolateral tibial apophysis, with a slightly curved tip (vs short, not curved, cf.
Fig. 38B
and fig. 11B in Mu
et al.
[2022]), 3) the rectangular conductor (vs triangular, cf.
Fig. 38C
and fig. 11C in Mu
et al.
[2022]), and 4) the anteriorly wide, posteriorly narrow median septum (vs anteriorly narrow, posteriorly wide, cf.
Fig. 38E
and fig. 11E in Mu
et al.
[2022]).
