Family VANHOEFFENIIDAE Attems 



Vanhoeffeniidae Attems, 1914, Arch. Naturg., Abt. A, vol. 80, p. 158; 1940, 

 Das Tierreich, Lief. 70, p. 162. 



Jeekel (1956, Beaufortia, vol. 51, p. 77) places Vanhoeffenia as a junior 

 synonym of Gnomeskelus Attems, a genus of the family Sphaeriotrichopidae. 

 As that family name has several years priority over the name Vanhoeffeniidae, 

 the latter name must be placed into synonymy. The considerable number 

 of polydesmoid genera not confamilial with Gnomeskelus and previously 

 placed in the Vanhoeffeniidae, now need a new family name. Because of 

 the very confused condition of the taxonomy of the small polydesmoids, it 

 is felt that no ends would be served by the premature selection of some of 

 the possibly available names, or by the proposal of a new one for the 

 American genera.
