| Popis: | Kudoa leptacanthae n. sp. was identified within the pericardial cavities of two apogonid species, Zoramia leptacantha and Zoramia viridiventer, from waters off Lizard Island on the Great Barrier Reef. The species shows a close taxonomic affinity, both morphologically and genetically, to Kudoa shiomitsui Egusa & Shiomitsu 1983 reported from a tetraodontid and scombrid, both from Japan. The infection was at high prevalences (average = 75.8% ± 0.63, n = 343) within schools of the two host species. Different sporogonic stages ('developing' and 'fully-developed') were observed in pseudocysts within the pericardium of the hosts. Kudoa leptacanthae n. sp. appears to be a persistent infection within the Zoramia species hosts. No seasonal variation was detected for this host/parasite system and the parasite did not affect host condition, when assessed using host length/weight ratio as a coarse indicator. We hypothesise that a source of infection in close proximity to the home patch reef of apogonid schools may lead to the high prevalence and intensity of infection reported in this study. |
