| abstract | The genus Copidognathus is well represented in the marine mite fauna of Hong Kong, with 21 species obtained from samples collected in April 1989. Three species, viz., Copidognathus umbonatus sp. n., C. acanthoscelus sp. n., and C. monacanthus sp. n. are described and figured in the present paper. In addition, Copidognathus spinula (Trouessart, 1899) is redescribed, a species recorded from Vietnam and being closely related to C. monacanthus. |
