First Report of <i>Hemicycliophora conida</i> (Nematoda: Criconematidae) on <i>Juncus maritimus</i> in Jordan

During a study of nematodes associated with aquatic plants in Jordan, a species of the sheathoid nematode <i>Hemicycliophora conida</i> Thorne, 1955 was recovered from soil associated with roots of sea rush plants, <i>Juncus maritimus</i> 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 <i>H. conida</i> in Jordan. This sheathoid nematode's presence could adversely affect plants like <i>J. maritimus</i>, which are of industrial, medicinal, and environmental significance. The impact of <i>H. conida</i> on this aquatic and other aquatic plants in the Zarqa River needs to be studied further.
