Abstract
1. A detailed historical account of the subfamily Haplorchinae is given. The systematic position of the various species in this group is critically reviewed. The subfamily Haplorchinae and the genus Haplorchis are accepted as valid while Monorchotreminae and Monorchotrema as synonyms.2. Three species of Haplorchis are found in Kwangtung Province, namely, H. pumilio (Looss 1896), H. taichui (Nishigori 1924), and H. yokogawai (Katsuta 1932).3. Throughout the work emphasis is laid on the acetabular spines or hooks which are considered to be the only recognisable constant structure practical enough for specific diagnosis.4. It is believed that there are only four valid species of Haplorchis, namely, H. pumilio, H. yokogawai, H. taichui, and H. milvi. The validity of H. milvi, however, is in question. H. cahirinus and H. anguillarum do not fit into the diagnosis of the subfamily Haplorchinae, while H. microrchia and H. taihokui fall into synonymy with H. taichui and H. pumilio respectively.5. A key for the identification of the known species is given.
