Type material. Holotype ♁, CHINA: Yunnan Province: Dali Bai Autonomous Prefecture, Nanjian Yi Autonomous County, Fenghuang Mountain (24°53′33.35″N, 100°19′42.67″E, 2294 m a.s.l.), 26 Jul. 2021, leg. Yannan Mu.
Paratypes: 6 ♀, with same data as holotype.
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).

Coloration. Carapace dark brown, with several shapes resembling flowing water droplets beside fovea.Abdomen black, dorsum nearly entirely covered by scutum, with pair of oval yellow markings near middle and two W-shaped stripes posteriorly (Fig. 28A, B). Legs yellow, with black annuli near tip of femora and tibiae.
Palp as in Figs 29A–D, 30A–C. Femoral apophysis protruding slightly, round, at middle parts of femur. Retrolateral tibial apophysis strongly curved, arc-shaped in ventral view; dorsal tibial apophysis smaller than retrolateral tibial apophysis, with broad base and thin tip, leaf-shaped in dorsal view. Tegulum slightly wider than cymbium, oval; tegular apophysis small, triangular, located at retrolateral tip of tegulum. Sperm duct distinct, tapering from retrolateral side of tegulum to embolus. Embolus short, base wide, triangular, tip curved towards retrolateral side of cymbium tip. Conductor narrow, transparent.

Carapace color and pattern same as male, abdomen black, without dorsal scutum, covered by fluff, several white spots and stripes faint in dorsal view (Fig. 28C, D).
Epigyne as in Figs 29E–F, 30D–E. Epigynal plate weakly sclerotized, posterior edge straight. Median septum absent. Copulatory openings round, located at middle of plate. Copulatory ducts not visible.
