Criconemella a Vicenniae N. Sp. (Nematoda: Criconematidae) and Enchodel Us Coomansi N. Sp. (Nematoda: Nordiidae) Associated With the Roots of the Mangrove Avicennia Marina (Forsk.) Vierh

Abstract

Two new species of nematode associated with the roots of mangroves, Avicennia marina are described, namely Criconemella avicenniae sp. nov. (Tylenchida, Criconematidae) and Enchodelus coomansi sp. nov. (Dorylaimida, Nordiidae). Both new species were found in the Hunter River estuary in south-eastern Australia where they occur in intertidal mud-flats. Criconemella avicenniae is close to C. goodeyi and C. paragoodeyi, but has more annules than both and different body proportions. Enchodelus coomansi differs from other species in possessing a tail spike in both sexes and in the more numerous medioventral supplements in the male.
