Namely, we had an opportunity to examine the holotype male and paratype females of O. formosanus , which were borrowed from the Taiwan Agricultural Research Institute. The aedeagal knob of formosanus (Fig. 22) is noticeably smaller than that of rubicundus (Figs. 15–17); and the female peritreme is straight distally in formosanus (Figs. 20–21) but hooked distally in rubicundus (Figs. 12–14). The female spinneret of formosanus is approximately as long as broad (Figs. 18–19), while in rubicundus it is slightly longer than broad, but sometimes approximately as long as broad (fig. 2 of Ehara, 1971). In addition, the female of rubicundus is red in color but the body color of female formosanus is not known.

Specimens examined. The type series of O. rubicundus was examined, in comparison with the holotype and a few paratypes of O. formosanus (Taipei, sugarcane).
