Paravulvus moroccanus sp. n., collected in the Moroccan eastern High Atlas, is described and illustrated. The new species is characterized by its 1.06-1.36 mm long body, lip region offset by marked depression and 11-13 µm broad, mural tooth solididentoid and 5.5-6.5 µm long, neck 229-270 µm long, pharyngeal expansion 108-126 µm long or occupying less than one-half (42-48%) of total neck length, uterus 27-47 μm long or 0.7-1.1 times the corresponding body diameter, V = 46-56, paravulvae absent, female tail rounded conoid (21-27 µm, c = 42-64, c' = 1.1-1.5), and male unknown. The taxonomy of Paravulvus is updated, with comments on its definition, a discussion of its relationships, and the provision of a list of species along with a key to their identification and a compendium of their morphometrics.
