Synonym}' after Van Cleave and Mueller, 1934. 



Hosts : Ictalurus nehulosus B.C. Bangham & Adams, 1954 



IctalurUrS nebulosus Idaho Fritts, 1959 



Additional hosts from other areas listed by Van Cleave and Mueller (1934) 

 and Harmes (1959). 



Morphology : The adult was figured and described by Van Cleave and Mueller 

 (1934). 



Biology : Xiphidiocercariae develop in species of Helisoma and encyst in mayfly 

 and dragonfly larvae (McMullen, 1935; Crawford, 1937). 



Haplometrana intestinalis Lucker, 1931 



Synonym: Haplometrana iiiahcnsis Olsen, 1937 (Waitz, 1959)

Rana pretiosa Idaho Waitz, 1959 



Morphology: The reader is referred to the original description by Lucker (1931) 

 and Olsen (1937) for morphological information. 



Biology : Lophocercous xiphidiocercariae develop in Physella titahensis; frogs 

 serve as both intermediate and definitive hosts (Olsen, 1937). 



Lechriorchis plesientera Sumwait, 1926 



Hosts : Thamnophis sir talis Wash. Sumwait, 1926 



Thamnophis ordinoides Wash. Sumwait, 1926 



No other records of this parasite are known. The taxonomic position of 

 this form is not completely clear. Skrjabin and Antipin (1957) placed this para- 

 site in the family Ochetosomatidae. They also described and figured the form. 



Neoglyphe locellus (Kossack, 1910) Yamaguti, 1958

O. {Neoglyphe) locellus (Kossack, 1910) Shaldybin, 1954

Also reported from Russia by Kossack (1910). 



Taxonomy: Neoglyphe (Shaldybin, 1954) Yamaguti, 1958, was erected for those 

 species of Opisthioglyphe found in mammals. Doll f us (1957) and Macy 

 and Moore (1958) .still retained Opistohioglyphe and the final decision on the 

 proper designation must come later.
