D178525DFFECFFA6FF4B6ECD0BDCDA8B.taxon	discussion	Remarks. The new species is unique among members of the genus for having the tubercula pubertatis in xix – xxiii and clitellum in xvi – xxiii. Righiodrilus viseuensis n. sp. is similar to R. tinga (Righi, 1971) and R. schubarti (Righi, Ayres & Bittencourt, 1978) in the number and position of the spermathecae. R. schubarti differs from the new species by the position of the clitellum at xv – xxiv, and R. tinga differs from the new species by male pores in xvii / xviii. R. viseuensis n. sp. is also similar to R. tico (Righi, 1982) by having the male pores in 1 / 2 xix; the latter species differs by the position of tubercula pubertatis in 1 / 2 xix – 1 / 2 xxi.	en	Santos, Bianca Tamires Silva Dos, Bartz, Marie Luise Caroline, Hernández-García, Luis Manuel, Rousseau, Guillaume Xavier, Martins, Marlucia Bonifácio, James, Samuel Wooster (2017): New earthworm species of Righiodrilus (Clitellata, Glossoscolecidae) from eastern Amazonia.
