.
Etymology.
This specific is named for its similarity to
O. dentigera
Mu & Zhang, 2021
.
Diagnosis.
This new species resembles
O. dentigera
in having a similarly shaped embolus, but it can be recognized by: 1) the semicircular prolateral tibial apophysis (vs triangular, cf.
Fig. 50A
and fig. 5A in
Mu & Zhang [2021]
), 2) the retrolateral tibial apophysis narrowing abruptly near the middle, with a digitiform tip (vs tapering from base to tip, cf.
Fig. 50B
and fig. 5F in
Mu & Zhang [2021]
), 3) the oval spermathecae (vs clavate, cf.
Fig. 50F
and fig. 5I in
Mu & Zhang [2021]
), and 4) the absence of glandular appendages (vs clavate, cf.
Fig. 50F
and fig. 5I in
Mu & Zhang [2021]
).
