The nematode Paraleptus chiloscyllii Yin et Zhang, 1983 (Physalopteridae) is redescribed on the basis of new material collected from the stomach of the Arabian carpetshark Chiloscyllium arabicum Gubanov (Hemiscylliidae) from marine waters off Iraq. Originally, P. chiloscyllii was found in C. plagiosum (Anonymous [Bennett]) from Fujian, China, but its description was rather poor and some important morphological features, such as deirids, shape and number of structures surrounding mouth, ventral unpaired papilla on the anterior cloacal lip, among others, were overlooked. It differs from its congeners in the shape of spicules and body length, although is very similar to the type species, P. scyllii Wu, 1927, only differing in the inequality of spicules. The generic diagnosis of Paraleptus was amended. Paraleptus minnanensis (Damin et Heqing, 2001) is considered a junior synonym of P. chiloscyllii and some morphological details of the posterior end of a male of P. australis Johnston et Mawson, 1943 are provided. The present finding of P. chiloscyllii in C. arabicum from off Iraq represents new host and geographical records.
