A new species of Okamejei is described based on two adult males collected from deep waters in the South China Sea. The new species, Okamejei picta sp. nov., is readily distinguished from most other congeners in having densely scattered black spots on dorsal disc. Okamejei hollandi and O. mengae is quite similar to the new species by their spot patterns on dorsal disc, but the new species differs from the former by a combination of characters: a yellowish brown dorsal surface densely covered with small, circular to irregular-shaped black spots; blotches on dorsal disc indistinct; posterior ocellus absent; ventral disc white; disc length 45.0-47.7% TL; distance between cloaca to caudal-fin tip 53.6-55.1% TL; trunk centra 31; total basal radials 73-76, morphology of clasper terminal skeleton, and lacking component funnel at the clasper end.
本文基于在南海深海采集到的两个成体雄性，描述了一新种——Okamejei picta sp. nov.。新种与大多数近缘种的区别在于其背部盘上有密集分布的黑色斑点。Okamejei hollandi 和 O. mengae 与新种在背部盘上的斑点模式非常相似，但新种与前者的区别在于：背部表面呈黄褐色，布满小的圆形至不规则形状的黑色斑点；背部盘上的斑块不明显；后眼缺失；腹盘白色；盘长占 TL 的 45.0-47.7%；肛孔至尾鳍末端的距离占 TL 的 53.6-55.1%；躯干中心 31；总基辐射 73-76，肛前器末端骨骼形态，且无肛前器末端的组成漏斗。
