The Asian tapeworm Khawia sinensis Hsü, 1935 (Cestoda: Caryophyllidea) is a large-sized (body length up to 11.5 cm) monozoic (unsegmented) parasite of common carp (Cyprinus carpio L.) that may cause mortality of young fish (fry). Since the 1960s, this cestode successfully colonized a large part of Europe, including the British Isles, North America and Japan. However, a review of published records provides evidence that the tapeworm K. sinensis, invasive parasite of carp, has become less common during the last two decades. Decline of K. sinensis may have been related to the recent introduction of another invasive tapeworm, the caryophyllidean Atractolytocestus huronensis Anthony, 1958 to Europe. Other factors that may have caused that K. sinensis is much less common than previously are also briefly discussed. A comparison of K. sinensis from feral and cultured carp, published to date, with those recently found for the first time in wild populations of carp in Slovakia did not reveal any marked differences in their morphology or measurements.
