Meyrick proposed Orsotricha for Topeutis venosa Butler, from Chile, 

 and subsequently associated with it Pleurota literatella Busck and 

 Orsotricha raptans Meyrick, and placed the genus in the family 

 Oecophoridae. 



Butler's Topeutis venosa, the type of the genus Orsotricha, was 

 described from a single female. Both the genitalia and the wing 

 venation, particularly the crossvein between vein 8 and the cell of 

 the hindwing, indicated at the time of the study of the Me3"rick types 

 that the species belonged in the Gelechiidae. Recent study of a male, 

 the second specimen known, confirms this relationship and I hereby 

 transfer Orsotricha to the Gelechiidae.
