Etymology.
The specific name is derived from the Latin word “
impletus
”, referring to the satisfaction derived from naming this species; adjective.
Diagnosis.
This new species resembles
O.celata
in having round copulatory openings and globular spermathecae, but can be recognized by: 1) the curved, arc-shaped retrolateral tibial apophysis (vs not curved, cf.
Fig. 29C
and fig. 2B in Fu
et al.
2016), 2) the longer, upwards-extending embolus curved towards the retrolateral side of the cymbium (vs short, not curved, cf.
Fig. 29C
and fig. 2B in Fu
et al.
2016), 3) the smaller, ridge-shaped tegular apophysis (vs large, triangular, cf.
Fig. 29C
and fig. 1D in Fu
et al.
2016), 4) thinner, longer connecting tubes (vs thick and short, cf.
Fig. 29F
and fig. 1G in Fu
et al.
2016).
