This species was described by Travassos (1923) as the type of a 

 new genus, MacroMlharnia. On analysis, the characters given by 

 Travassos do not appear to differ sufficiently from those of the genus 

 Ormthohilharnia Odhner to justify the recognition of Macrohilharzia 

 as a distinct genus. The body ,form, the disposition of the large 

 number of small testes, and the position of the seminal vesicle are 

 the same as for species of O rnithohilharzia. Its size, admittedly, 

 is unusual for this genus, but size alone can not be regarded as a 

 character of generic value.
