Etymology.
The species name is derived from the
type
locality; noun in apposition.
Diagnosis.
This new species resembles
O. hamata
in having a similarly slanted embolus, but can be recognized by: 1) the larger, arch-shaped tegular apophysis (vs small and triangular, cf.
Fig. 53C
and fig. 9G in
Wang
et al.
[2012]
), 2) the absence of a conductor (vs with conductor, cf.
Fig. 53C
and fig. 9G in
Wang
et al.
[2012]
), 3) the blunt-tipped retrolateral and shorter dorsal tibial apophyses (vs sharp-tipped retrolateral tibial apophysis tip and long dorsal tibial apophysis, cf.
Fig. 53D
and fig. 9F in
Wang
et al.
[2012]
), 4) the smaller, oval copulatory openings (vs large and arc-shaped, cf.
Fig. 53E
and fig. 9H in
Wang
et al.
[2012]
), and 5) the smaller, closely situated spermathecae (vs separated by about one spermatheca diameter, cf.
Fig. 53F
and fig. 9I in
Wang
et al.
[2012]
).
