Orstomella yaliuensis n. sp., a xarifiid copepod (Crustacea) parasitic in the polyps of hump coral Porites lutea Milne Edwards & Haime off Taiwan

Multiple parasitic crustacean infestation on belonid fish Strongylurastrongylura

Simultaneous multiple infestation of parasitic crustacean species involving a cymothoid isopod, Cymothoafrontalis Milne Edward, 1840 and four species of copepods such as Lernanthropustylosuri Richiardi, 1880, Caligodeslacinatus Kroyer, 1863, Bomolochusbellones Burmeister, 1833 and Dermoergasiluscoleus Cressey & Collette, 1970 was frequently noticed on spot-tail needlefish, Strongylurastrongylura (Belonidae) captured from the Malabar coast (Kerala, India) during the period from April 2011 to March 2012. All the 43 fishes (Strongylurastrongylura) collected, were under the hyper-infection with parasitic crustaceans; a total of 388 parasitic crustaceans including 57 Cymothoafrontalis, 252 Lernanthropustylosuri, 31 Caligodeslacinatus, 24 Bomolochusbellones and 32 Dermoergasiluscoleus were recovered from the host fish. 4 members (9.30%) of host fish were under quadruple parasitism, in two different combinations. Seventeen (39.53%) host fishes showed triple parasitism and 20 (46.51%) members exhibited double parasitism, with four and five parasitic combinations respectively. Remaining two (4.65%) fishes were parasitized only by the copepod, Lernanthropustylosuri. The infestations by all recovered parasitic crustaceans were highly site specific. The damage caused by the parasitic crustaceans was also discussed.

Four new xarifiid copepods (Poecilostomatoida) associated with the scleractinian coral Pavona explanulata (Lamarck) from off Taiwan

Four new xarifiid copepods are described. They were found in association with the scleractinian coral Pavona explanulata (Lamarck) occurring in shallow water reefs off Yenliao in northern Taiwan. The four species are: Xarifia capillata n. sp., X. parva n. sp., X. pavonae n. sp. and X. taiwanensis n. sp. They were found together in a single washing of the host coral. Previously, 13 species of copepods have been found in association with nine species of Pavona Lamarck. More than half (7/13) of these symbionts are members of Xarifia Humes, 1960.
