Abstract: | Adults and deutonymphs of a new water mite species of the genus Hygrobates Koch, 1837 (Acari, Hydrachnidia, Hygrobatidae) were found to parasitize the Hong Kong Newt, Paramesotriton hongkongensis Myers and Leviton, 1962 (Amphibia, Caudata, Salamandridae), endemic to Hong Kong and coastal areas of Guangdong Province: Hygrobates aloisii sp. nov. Males and females, as well as deutonymphs and larvae are described. A new subgenus - Lurchibates subgen. nov. - is defined to accommodate the species of the Hygrobates salamandrarum-group. The parasite-host association, infestation rate, attachment sites and the impact of mite infestation on the newts behaviour and body condition are investigated. These ecological aspects of the parasite-host association between freshwater mites and newts are examined for the first time in detail in their natural habitat. |
