First Report of Hemicycliophora conida (Nematoda: Criconematidae) on Juncus maritimus in Jordan

During a study of nematodes associated with aquatic plants in Jordan, a species of the sheathoid nematode Hemicycliophora conida Thorne, 1955 was recovered from soil associated with roots of sea rush plants, Juncus maritimus Lam., from the Zarqa River. Morphological, morphometric, and molecular data of recovered females and males of this nematode are included. This study represents the first record of H. conida in Jordan. This sheathoid nematode’s presence could adversely affect plants like J. maritimus, which are of industrial, medicinal, and environmental significance. The impact of H. conida on this aquatic and other aquatic plants in the Zarqa River needs to be studied further.
