Etymology.
This specific is named for its similarity to
O. forcipata
Yang, Wang & Yang, 2013
.
Diagnosis.
This new species resembles
O. forcipata
in having a similarly shaped embolus and connecting tubes, but can be recognized by: 1) the absence of a conductor (vs with conductor, cf.
Fig. 44B, C
and fig.
9 in
Yang
et al.
[2013]
), 2) the presence of a mastoid-shaped apophysis on the retroventral side of the tibia (vs without, cf.
Fig. 44C
and fig.
10 in
Yang
et al.
[2013]
), 3) the blunt tip of the retrolateral tibial apophysis, with a slender branch at the base prolaterally (vs tip bifurcate, without a branch, cf.
Fig. 44B
and fig.
10 in
Yang
et al.
[2013]
), and 4) the wider, wavy-shaped posterior edge of the epigynal plate (vs narrow, M-shaped, cf.
Fig. 44E
and fig.
13 in
Yang
et al.
[2013]
).
