Abstract

A new genus is proposed for Orneoascaris [ = Amplicaecum] alata (Baylis, 1947) Le Van Hoa, 1960. The new genus is defined and differentiated from Orneoascaris by the posterior position of the vulva and by the wide cervical alae. It is differentiated from Ophidascaris by fewer postcloacal papillae and spicules less than half the length of the ejaculatory duct. From both genera alata differs in the unique form of the lips and in the more extensive U-shaped enlargement of the nucleus of the dorsal oesophageal gland. It is suggested that this species is a specialized form, possibly of neotropical origin.
