Abstract

Four new species of Hurleytrematoides Y amaguti, 1954 are described: H. fl}iensis from Heniochus acuminatus pnd Chaetodon citrinellus, H. prevoti from Chaetodon melannotus; H bartolii from Heniochus acuminatus and H monoceros, and H. zebrasomae from Zebrasoma scopas. The hurleytrematine genera Hurleytrema, Hurleytrematoides, Pseudohurleytrema and Parahurleytrema are briefly discussed and their validity accepted based chiefly on the structure of the male and female terminal structures. Hurleytrema pyriforme Overstreet, 1969 and H. catarinensis Amato, 1982 are transferred to Pseudohur/eytrema as new combinations. The generic diagnosis of Hurleytrematoides is emended to include cirrus with large and extensive spines or small ones with limited distribution, and a spiny or aspinose unipartite terminal organ. A key to the hurleytrematine genera with single testis and their species is given. A parasite-host list of all monorchiid species reported to date is included.
