TY - JOUR AB - Cucullanus brevicaudatus n. sp. (Cucullanidae) is described from the intestine of Balistes capriscus Gmelin (Balistidae) off Rio de Janeiro, Brazil. The new species can be differentiated from its congeners in the small body length, the shape of the gubernaculum, the particular size and morphology of the tail in both males and females, the arrangement of the caudal papillae, the narrow oesophageal base, and the eggs with rugged shells. In addition, the combination of some features, i.e. number of caudal papillae, spicule length, oesophagus/body length ratio, host family and geographical distribution, can help to easily distinguish the new species from other cucullanids. Considering these features, C. brevicaudatus differs from the species assigned to Dichelyne Törnquist, 1931 which exhibit morphological proximity with Cucullanus Müller, 1777. Regarding the life-cycle of cucullanid nematodes, available evidence suggests that some species are primarily heteroxenous using invertebrates (i.e. crustaceans, polychaetes) as intermediate hosts, but in other a histotrophic phase in the definitive host replaces the intermediate host.
