G. Righi, A NEW EARTHWORM (OCNERODRILIDAE, OLIGOCHAETA) FROM A BRAZILIAN CAVE AND CONSIDERATIONS ABOUT BELLADRILUS, Revue Suisse de Zoologie, 102(2), 1995, pp. 361-365
Belladrilus (B.) otarion, n.sp. is described from a cave in Sao Paulo
State, Brazil. The excess of partner's spermatozoa is resorbed in the
ental part of the spermathecal duct. The Belladrilus genus and its two
subgenera (Belladrilus s.s. and Santomesia) are reevaluated. A key to
Belladrilus species is presented.
