摘要：A new species of Haematoloechus is described from the lungs of Rana boylii from Humboldt County,California. The new species is similar to Haematoloechus buttensis, Haematoloechus kernensis, and Haematoloechuscomplexus in general course of the uterus and gonad shape. It is similar to H. buttensis by having a cirrus sac terminatingmidway between the posterior margin of the pharynx and the anterior margin of the ovary, and having a smaller oral/ventral sucker ratio; to H. complexus by having the genital pore ventral to the pharynx, and it is similar to H. kernensisby having a larger oral sucker to pharynx width ratio. The new species is unique by lacking an extra-cecal longitudinaluterine loop from the hind-body. Molecularly, the new species differs 1.04–1.15% in partial 28S sequence with respectto H. complexus, and a monophyletic grouping of these specimens in a phylogenetic analysis of all available sequencedata consistent with the species-specific status proposed herein. Evidence is also presented to suggest that specimensidentified as H. buttensis in Rana pretiosa from British Columbia, Canada represents a new, but still undescribed species.The importance of conducting biological inventories of helminths, along with continued monitoring of populations, andcollections based taxonomy are related.
