| Abstract |
Adoncholaimus papillatus Kreis, 1932 and Viscosia erasmi sp.nov. are described from an intertidal area of the Sundays River Estuary, South Africa.Adoncholaimus papillatus females have an, up to present, unknown organization of the demanian system: the main duct is connected with the two spermathecae by means of a strongly curved ductus uterinus. There is only one osmosium situated at the anterior part of the main duct (anteriad of the vagina). The uvette and the ductus entericus are absent. The main duct extends to the swollen part of the tail where it opens in one or two terminal pores.Viscosia erasmi sp.nov. is mainly characterized by the bifid apical part of the buccal cavity, three distinct teeth with the right ventrosublateral one the largest and by the setiform head sensilla. |
