Genus LISTROGNATHUS Tschek 



Townes (1970) recognized five subgenera, two of which have Nearctic species. In their tribal 

 revision, Townes and Townes (1962) erroneously treated the name Listrognathus as being of 

 feminine gender. If one chooses to ignore the provision in the Code (art. 30, [a], [i], [3]) regarding 

 the genders of Greek generic names latinized with a change in termination, it is inconsistent to 

 also ignore the scholarly work of Hopper (1959). Hopper regarded Listrognathus as masculine, 

 which is apparently explained by his statement that "a large proportion of the compounds of 

 Greek nouns are adjectives by Greek grammar and may be either masculine or feminine .... and 

 in such cases the gender must be considered to be determined by the first species included 

 whose name is of definite gender" (in this case L. comidus Tschek).
