Etymology.
The species name is derived from the
type
locality; noun in apposition.
Diagnosis.
This new species resembles
O. horizon
sp. nov.
in also having a transverse embolus, but can be recognized by: 1) the smaller retrolateral tibial apophysis (vs large, cf.
Fig. 56D
and
Fig. 34D
), 2) the large dorsal tibial apophysis (vs without dorsal tibial apophysis, cf.
Fig. 56D
and
Fig. 34D
), 3) the copulatory openings extending posteriorly (vs extending anteriorly, cf.
Fig. 56E
and
Fig. 34E
), 4) the thinner copulatory ducts, extending anteriorly (vs extending posteriorly, cf.
Fig. 56E
and
Fig. 34E
), and 5) the distinctly separated connecting tubes (vs close to each other, cf.
Fig. 56F
and
Fig. 34F
).
