Diagnosis. Dimensions 178–219 mm by 5.5–7.4 mm in x, 5.4–7.8 mm in xxx, 5.0– 7.7 mm in clitellum; body cylindrical throughout, segments 132–150. First dorsal pore at 11/12. Clitellum annular, xiv–xvi; smooth. Female pore single on xiv. Male pores on xviii, with around 7 genital markings, 8–11 setae between male pores. Spermathecal pores lateral at 7/8–8/9, 3 genital markings arranged in front at 8/9 spermathecal pore. Prostates large in xviii, extending to xvii and xxi.
Remarks. Tsai (1964) mentioned this species with the prostates occupying xviii–xxii, and 12–19 setae between the male pores. Specimens collected from eastern Taiwan have large prostates occupying xvii–xxi, and with only 8–11 setae between male pores, which slightly differs from Tsai’s (1964) description. The difference in external and internal characters may represent intraspecific variations.
