Species ofthe genus Hydropsycheare largely distributed over the islands ofthe West Pacific.
Theyaregroupedinto4speciesgroupson thebasisofmalegenitaliccharacters.Thehitherto
known species ofthe4 groupsare listed, and thedistributional areaofthegroups isdemon-
strated.Amongthe57citedspecies 16arenewlydescribed: H.germanorumsp.n., H.staphylo-
