Diagnosis

This species can be separated from all other species of Oxidus by its much darker, almost uniformly dark brown body, slender base of gonopod solenophore, more clearly and obtusely emarginated posterior edge of telson; smaller postfemoral lamina l; stouter spine z; process h more erect, slender and pointed; the base of solenophore less protruded, more strongly rounded; mesal lobule distinctly separated from rounded solenophore tip.

Remarks

The species was originally described by Verhoeff (1937) under the genus Orthomorpha , then was assigned to the genus Oxidus by Takakuwa (1954).

Distribution

South Japan (Ryukyu Islands): Ishigaki-jima, Yonaguni-jima; Taiwan.
