The female is 433-646 $\mu\textrm{m}$ long: a＝ 29.1-37.5, b ＝ 5.1-6.4, c ＝ 15.0-21.3, vulva(%) ＝ 73.0-85.4. The male body length is 408-512$\mu\textrm{m}$ long: a＝36.1-40.0, b＝4.8-6.7, c ＝17.0-19.0, and spicule ＝ 14.1-18.0 $\mu\textrm{m}$. The stylet is 11.6-18.0 $\mu\textrm{m}$ long and the number of incisures is four.
